Help with our Outlook products<\/p>\n

Find answers about compatibility, installation, mail merge,
\nattachments, duplicate items, automatic printing, licences,
\nupdates and support for our Outlook add-ins.<\/p>\n

Important:<\/strong>
\nMost of these add-ins are designed for classic Microsoft Outlook
\nfor Windows. Please check the system requirements shown on the
\nrelevant product page before purchasing.<\/p>\n<\/header>\n

\n

General questions<\/h2>\n
\nWhat is an Outlook add-in?<\/summary>\n
\n

An Outlook add-in adds features to classic Microsoft Outlook.
\nDepending on the selected product, an add-in can personalise
\nmail merge messages, process attachments automatically, find
\nduplicate Outlook items or print incoming documents.<\/p>\n

Once installed, the add-in is normally integrated into the
\nOutlook interface. Its features may appear in the ribbon,
\na context menu or a dedicated product window.<\/p>\n<\/div>\n<\/details>\n

\nDo the add-ins work with the new Outlook for Windows?<\/summary>\n
\n

Most traditional Outlook add-ins use Microsoft Office COM
\nadd-in technology and are intended for classic Outlook for
\nWindows.<\/p>\n

The new Outlook for Windows uses a different technical
\narchitecture and does not support traditional COM add-ins in
\nthe same way. Please check the compatibility information on
\nthe relevant product page before purchasing.<\/p>\n<\/div>\n<\/details>\n

\nCan I use the add-ins with Microsoft 365?<\/summary>\n
\n

Many add-ins can be used with the classic Outlook desktop
\napplication for Windows included with certain Microsoft 365
\nplans.<\/p>\n

The Microsoft 365 subscription alone does not determine
\ncompatibility. The installed Outlook edition, Windows version
\nand product-specific system requirements must also be taken
\ninto account.<\/p>\n<\/div>\n<\/details>\n

\nDo the add-ins work with Outlook for Mac?<\/summary>\n
\n

The traditional Outlook add-ins offered in the shop are
\nprimarily designed for Outlook on Windows. They normally
\ncannot be installed in Outlook for macOS unless the product
\npage explicitly states otherwise.<\/p>\n<\/div>\n<\/details>\n

\nCan the add-ins be used with an Exchange mailbox?<\/summary>\n
\n

Many Outlook add-ins can work with local Outlook data files
\nand with mailboxes hosted on Microsoft Exchange or
\nMicrosoft 365. The exact functionality depends on the selected
\nproduct and the mailbox configuration.<\/p>\n

An Outlook add-in is different from a server-side Exchange
\napplication. A desktop Outlook add-in normally performs its
\ntasks on the computer on which Outlook and the add-in are
\ninstalled.<\/p>\n<\/div>\n<\/details>\n

\nDo the add-ins support 32-bit and 64-bit Outlook?<\/summary>\n
\n

Support for 32-bit and 64-bit Outlook depends on the selected
\nadd-in and product version. Please consult the system
\nrequirements on the corresponding product page.<\/p>\n

You can normally check your Outlook architecture under
\nFile \u2192 Office Account \u2192 About Outlook<\/strong>.<\/p>\n<\/div>\n<\/details>\n<\/section>\n

\n

Installation and configuration<\/h2>\n
\nHow do I install an Outlook add-in?<\/summary>\n
\n
    \n
  1. Close Outlook completely.<\/li>\n
  2. Download the installation file.<\/li>\n
  3. Run the installer, using administrator privileges if
    \nrequired.<\/li>\n
  4. Follow the steps shown by the installation wizard.<\/li>\n
  5. Restart Outlook after installation.<\/li>\n
  6. Enter your licence key if product activation is required.<\/li>\n<\/ol>\n

    Installation on a company-managed computer may be restricted
    \nby security policies. Contact your IT administrator if you do
    \nnot have permission to install software.<\/p>\n<\/div>\n<\/details>\n

    \nWhere can I find the add-in after installation?<\/summary>\n
    \n

    The add-in normally appears in the ribbon of classic Outlook.
    \nDepending on the product, it may add a new tab, button,
    \ndrop-down menu or context-menu command.<\/p>\n

    Some functions are only displayed while composing a message,
    \nselecting Outlook items or opening a particular Outlook folder.<\/p>\n<\/div>\n<\/details>\n

    \nThe add-in is not visible in Outlook. What can I do?<\/summary>\n
    \n

    Check the following points:<\/p>\n

      \n
    • Outlook was fully restarted after installation.<\/li>\n
    • The installed add-in supports your Outlook and Windows
      \nversions.<\/li>\n
    • The installation completed without errors.<\/li>\n
    • The add-in has not been disabled by Outlook.<\/li>\n
    • Security software has not blocked or removed any product
      \nfiles.<\/li>\n<\/ul>\n

      In classic Outlook, open
      \nFile \u2192 Options \u2192 Add-ins<\/strong>. Select
      \nCOM Add-ins<\/strong> under \u201cManage\u201d and check whether
      \nthe add-in is enabled.<\/p>\n<\/div>\n<\/details>\n

      \nHow can I temporarily disable an add-in?<\/summary>\n
      \n

      Open File \u2192 Options \u2192 Add-ins<\/strong> in classic
      \nOutlook. Select COM Add-ins<\/strong> under \u201cManage\u201d
      \nand open the management window.<\/p>\n

      Clear the checkbox next to the add-in to disable it
      \ntemporarily. Select the checkbox again to re-enable it.<\/p>\n<\/div>\n<\/details>\n

      \nHow do I uninstall an Outlook add-in?<\/summary>\n
      \n

      Close Outlook and open the list of installed applications in
      \nWindows. Select the relevant add-in and start the uninstall
      \nprocess.<\/p>\n

      Restart Outlook or Windows afterwards if requested by the
      \nuninstaller.<\/p>\n<\/div>\n<\/details>\n<\/section>\n

      \n

      Mail merge and personalised email<\/h2>\n
      \nCan I personalise the subject line of a mail merge?<\/summary>\n
      \n

      Yes. A suitable mail merge add-in can insert data fields into
      \nthe email subject as well as the message body.<\/p>\n

      For example, a generic subject such as \u201cYour documents\u201d can
      \nbecome \u201cYour documents for Jane Example\u201d for an individual
      \nrecipient.<\/p>\n<\/div>\n<\/details>\n

      \nCan I add attachments to mail merge messages?<\/summary>\n
      \n

      Yes. The same attachment can be added to every generated
      \nmessage. Depending on the selected product, multiple common
      \nattachments can also be included.<\/p>\n

      Mail merge is normally prepared in Microsoft Word. The
      \nadditional email and attachment options are selected before
      \nthe final messages are generated.<\/p>\n<\/div>\n<\/details>\n

      \nCan each recipient receive a different attachment?<\/summary>\n
      \n

      Yes. A column containing a file name or file path can be added
      \nto the data source. Each record can therefore refer to a
      \ndifferent attachment.<\/p>\n

      This can be used to send individual invoices, certificates,
      \nreports, contracts or other recipient-specific documents.<\/p>\n<\/div>\n<\/details>\n

      \nCan personalised PDF documents be created and sent?<\/summary>\n
      \n

      A suitable mail merge add-in can create an individual PDF
      \ndocument for each data record and attach it to the corresponding
      \nemail message.<\/p>\n

      Depending on the product version, personalised PDF, DOCX or
      \nother documents may also be exported as separate files to a
      \nselected folder without sending an email.<\/p>\n<\/div>\n<\/details>\n

      \nCan PDF or DOCX attachments be password protected?<\/summary>\n
      \n

      Depending on the mail merge product and edition, personalised
      \nPDF or DOCX files can be protected with a password. The same
      \npassword may be used for every file, or a separate password may
      \nbe assigned to each recipient.<\/p>\n

      For sensitive documents, the password should be communicated
      \nthrough a separate channel. Your organisation\u2019s data protection
      \nand security requirements must also be observed.<\/p>\n<\/div>\n<\/details>\n

      \nCan recipients see the other recipient addresses?<\/summary>\n
      \n

      A personalised sending function creates a separate message for
      \nevery recipient. The recipient therefore sees only the address
      \nassociated with that individual message.<\/p>\n

      This differs from sending one message to multiple addresses
      \nusing the To, CC or BCC fields.<\/p>\n<\/div>\n<\/details>\n

      \nCan I select a different sender account?<\/summary>\n
      \n

      If several email accounts are configured in Outlook, supported
      \nmail merge add-ins may allow you to select the account used for
      \nsending.<\/p>\n

      Sending as or on behalf of another Microsoft 365 or Exchange
      \nmailbox requires the relevant mailbox permissions. An Outlook
      \nadd-in cannot replace missing server permissions.<\/p>\n<\/div>\n<\/details>\n<\/section>\n

      \n

      Automatic attachment processing<\/h2>\n
      \nCan attachments from incoming messages be saved automatically?<\/summary>\n
      \n

      Yes. An attachment-processing add-in can save attachments from
      \nincoming messages to a designated folder automatically.<\/p>\n

      Rules can be created for particular senders, Outlook folders,
      \nfile types or other conditions. This makes it possible to
      \norganise invoices, orders, reports and other documents
      \nautomatically.<\/p>\n<\/div>\n<\/details>\n

      \nWhat happens to the attachment in the original message?<\/summary>\n
      \n

      Depending on the selected settings, the attachment can remain
      \nin the message, be removed, or be replaced with a link or text
      \nreference to the saved file.<\/p>\n

      Removing large attachments can reduce the size of an Outlook
      \ndata file. The external files must then be backed up reliably.
      \nDo not move or delete a storage folder while Outlook messages
      \nstill refer to files in that location.<\/p>\n<\/div>\n<\/details>\n

      \nCan attachments be compressed automatically?<\/summary>\n
      \n

      Yes. A suitable attachment-management add-in can compress
      \nfiles in incoming and outgoing messages as ZIP archives.
      \nPassword-protected archives may also be available.<\/p>\n

      Some email systems block executable or self-extracting archives
      \nfor security reasons.<\/p>\n<\/div>\n<\/details>\n

      \nCan the add-in provide access to blocked attachments?<\/summary>\n
      \n

      A suitable attachment-management function can change the list
      \nof file types blocked by Outlook.<\/p>\n

      Allowing access to blocked file types can create a security
      \nrisk. Files should only be opened when the sender and content
      \nare trusted and the change is permitted by your organisation\u2019s
      \nsecurity policy.<\/p>\n<\/div>\n<\/details>\n<\/section>\n

      \n

      Finding duplicate Outlook items<\/h2>\n
      \nWhich duplicate Outlook items can be detected?<\/summary>\n
      \n

      Depending on the selected product, duplicate email messages
      \nand posts or other Outlook items such as contacts, appointments,
      \ntasks, notes and journal entries can be detected.<\/p>\n

      Separate products may be required for duplicate email messages
      \nand other Outlook item types. Check the supported item types on
      \nthe corresponding product page before purchasing.<\/p>\n<\/div>\n<\/details>\n

      \nAre duplicates deleted immediately?<\/summary>\n
      \n

      Not necessarily. Depending on the selected action, duplicates
      \ncan be deleted, marked, copied or moved to another Outlook
      \nfolder.<\/p>\n

      For the first scan, moving possible duplicates to a separate
      \nreview or backup folder is recommended. Check the results
      \nbefore deleting any items permanently.<\/p>\n<\/div>\n<\/details>\n

      \nCan multiple folders be compared?<\/summary>\n
      \n

      Yes. Supported products can search selected folders or compare
      \nitems across multiple Outlook folders.<\/p>\n

      Depending on the Outlook environment, this may include local
      \nPST files, cached Exchange mailboxes and shared or public
      \nfolders. The first scan of a large mailbox may take additional
      \ntime.<\/p>\n<\/div>\n<\/details>\n<\/section>\n

      \n

      Printing emails and attachments<\/h2>\n
      \nCan incoming emails be printed automatically?<\/summary>\n
      \n

      Yes. A printing add-in can monitor selected Outlook folders and
      \nprint new messages automatically. Outlook rules can first be
      \nused to move matching messages into a monitored folder.<\/p>\n

      This can be used to print orders, invoices, reports or status
      \nnotifications automatically.<\/p>\n<\/div>\n<\/details>\n

      \nCan messages and attachments be printed separately?<\/summary>\n
      \n

      Yes. Depending on the configuration, the message, its
      \nattachments or both can be printed. A particular printer can
      \nbe selected, and processing can be restricted to specified
      \nfile types.<\/p>\n<\/div>\n<\/details>\n

      \nWhich attachment formats can be printed?<\/summary>\n
      \n

      Commonly supported formats include PDF documents, Microsoft
      \nOffice documents, spreadsheets and image files.<\/p>\n

      An appropriate application or printing component usually needs
      \nto be installed in Windows for each file type. Printing can be
      \nlimited to selected file extensions, such as PDF only.<\/p>\n<\/div>\n<\/details>\n

      \nCan documents stored in archives be printed?<\/summary>\n
      \n

      A suitable printing add-in can extract files from supported
      \narchive formats and print the documents stored inside them.
      \nSupported archive types may include ZIP, RAR, GZ and 7Z.<\/p>\n

      Encrypted archives require the correct password and may not be
      \nsuitable for a fully automatic workflow.<\/p>\n<\/div>\n<\/details>\n<\/section>\n

      \n

      Licence, updates and support<\/h2>\n
      \nCan I test an add-in before purchasing?<\/summary>\n
      \n

      A time-limited trial version is available for many Outlook
      \nadd-ins. The availability and possible limitations of a trial
      \nversion are shown on the relevant product page.<\/p>\n

      Use the trial period to check compatibility with your Outlook
      \ninstallation, mailbox and organisational security policies.<\/p>\n<\/div>\n<\/details>\n

      \nHow many computers can I use the add-in on?<\/summary>\n
      \n

      The permitted number of installations depends on the licence
      \nmodel of the selected product. A single-user licence,
      \nmulti-user licence and server licence may provide different
      \nusage rights.<\/p>\n

      The product description and applicable licence terms are
      \ndecisive.<\/p>\n<\/div>\n<\/details>\n

      \nHow do I receive product updates?<\/summary>\n
      \n

      Depending on the product, updates may be provided through an
      \nintegrated update check, a customer download area or a new
      \ninstallation download.<\/p>\n

      Before installing an update, check whether your licence or
      \nsubscription includes the new version. Close Outlook before
      \nstarting the update installation.<\/p>\n<\/div>\n<\/details>\n

      \nWhat information should I include in a support request?<\/summary>\n
      \n

      Please provide the following information where possible:<\/p>\n

        \n
      • Name of the add-in<\/li>\n
      • Order number<\/li>\n
      • Installed add-in version<\/li>\n
      • Outlook and Windows versions<\/li>\n
      • Exact wording of any error message<\/li>\n
      • Description of the steps that caused the problem<\/li>\n
      • A redacted screenshot, if helpful<\/li>\n<\/ul>\n

        Do not send account passwords or publish your full licence key.
        \nPersonal information in emails or screenshots should be removed
        \nor obscured before submitting a support request.<\/p>\n<\/div>\n<\/details>\n<\/section>\n
