My company has Office setup so we have to reset out passwords on an interval. I was using the Outlook 365 desktop client for Mac just fine before this. Now that the password needs updating, I went to do that. When doing that, now the desktop client says it cannot perform the action. So I had my administrator reset my password in the admin panel. After that, the desktop client says when trying to reconnect the account:
Your account can't sync because your Office 365 subscription hasn't been activated
I click activate, login through the window and it then says
No subscription
Your account can't sync because your Office 365 subscription hasn't been activated
It was working JUST FINE before all of this.
