Collaborator and Outlook
I personally started getting an issue. When I click on the envelope next to a review participants name, I get the error shown below. When I select 'email all', that works fine.
This is a new error, and seems to affect my only - others are not getting the issue. The outlook app is indeed at the path shown in the error box. Outlook is still a local app (not 365 yet) so that's not an issue.
Wanted to get the community's thoughts first, as when I go to IT they will just blame SB. 🙂
