Sorry to know about this and if you continue to experience an issue, you can either use the link below and download a lower version rather than the current ones which is on 16.111.

    Hello, good day and thanks for your question. Sorry to know about this and I understand that you have encountered an issue with regards to Microsoft 365 apps on your iMac.

    May I check and confirm if there is a specific error being shown when you are trying to use any of the Microsoft 365 app/s like Excel, Word or Powerpoint?

    Also, you may check and confirm that your account still has an active subscription by going at account.microsoft.com/services and login from there.
