Problem

thinkcell fails to send an email on macOS 10.14 and later

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

Explanation

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.

Solution

To authorize thinkcell on macOS 10.14.2 and later, tick the Mail checkbox in System Preferences > Security & Privacy > Privacy > Automation.
