Outlook Add-in Requirements

  • Make sure you’re either on Office 365 and using a Microsoft Exchange 2013 protocol (rather than an Exchange Active Sync protocol, for instance).

Important: According to Microsoft, POP and IMAP email accounts in Outlook do not support Office Add-ins.

Troubleshooting: New Outlook

If you’ve recently switched to the new Outlook for Mac, you may need to reinstall the DocSend Outlook Add-in for it to appear in your email composer.

  1. Click the “more options” menu in the Outlook toolbar.
  2. Select Get Add-ins.
  3. Search for DocSend and click Add.

The add-in should then be available from the “more options” menu when composing a new email in the main Outlook window.

Important: Currently, the add-in dropdown is only available in the main Outlook window of the new Outlook for Mac. If you choose to continue the message in a new window, the email composer will not include the add-in dropdown.
