think-cell is not authorized to send mail


think-cell fails to send an e-mail on macOS 10.14 and later

When I click Send Selected Slides..., Request Support... or Invite to think-cell trial..., think-cell displays an error message saying "think-cell has not been authorized to send mail" and a link to this article.


On macOS 10.14 and later, macOS asks if you want to authorize PowerPoint or Excel to send Apple Events to Mail. You may have denied this request in the past.


To authorize think-cell on macOS 10.14.2 and later, tick the Mail checkbox in System PreferencesSecurity & PrivacyAutomation.

mac security and privacy dialog

Prior to macOS 10.14.2 you can authorize think-cell as explained below:

  1. Open the Terminal application.

    In the Finder, go to Applications and then Utilities.

  2. In the Terminal, type tccutil reset AppleEvents and press Enter
  3. Now open PowerPoint and click on Send Selected Slides..., Request Support... or Invite to think-cell trial... again.
  4. A message box will appear saying "Microsoft PowerPoint" wants access to control "Mail". Allowing control will provide access to documents and data in "Mail", and to perform actions within that app. Press OK to confirm.
