Outlook calendar on mac not showing up

[Amanda_Val]

I'm using a Mac (macOS Big Sur version 11.0.1) and using Microsoft Office 365 (Microsoft Outlook for Mac version 16.43).  Email is working (and syncing) fine to my Yahoo and Gmail accounts.  However, recently I have lost the function of the Calendar.  It is essentially blank. 

I've tried reinstalling Outlook which did not change anything.  Any ideas?

@Amanda_Val Definitely sounds like a outlook profile issue.
I would do a complete clean of everything that has to do with Outlook for mac and then re-configure it to get a totally clean installation and profile.

@Amanda_Val did you find a solution to this? I have the same problem I think maybe after an update.

@DKairyNo, I had to reinstall the OS with the help of an apple rep.
