Working a set of our TLC Creative show computers I had this frustrating error when attempting to open the MS Teams based presentation:
I confirmed MS Teams was logged in with my credentials. Confirmed I can access the Team, folder and file. I also confirmed I was able to open the PowerPoint file in the Teams viewer and web-based browser version of PowerPoint. But I did not confirm PowerPoint/MS Office was logged in with my account – the user seen in the upper right of PowerPoint.
Each time I went through the process of logging myself as the profile for Office to use, the above error taunted me (argh!!). The solution, which I have confirmed works on yet another computer having the same Microsoft seizure, is to SIGN OUT of all profiles. Then sign in with your credentials. I have no idea why Office errors out when trying to login your profiles sometimes, but it does. And I now have a solution that works (but sorry to everyone else that needs to also use that computer and must go through the login profile process vs. just clicking to change profiles…).
