To sign back into Microsoft 365 on your iMac and resolve the issue with saving your Excel spreadsheet, follow these steps:
- Open Excel: Start by launching Excel on your iMac.
- Sign Out: If you see your name or profile picture at the top, click on it and select Sign out.
- Sign In: After signing out, click on Sign in and enter your Microsoft 365 credentials (make sure you are using your Work or School account).
- Check License: Ensure that your Microsoft 365 subscription is active and that your account has the necessary licenses assigned. You might need to check this in the Microsoft 365 Admin Center if you have admin access.
- Restart Excel: If you still encounter issues, try closing Excel completely and reopening it to see if the sign-in process completes successfully.
If you are still unable to save your work after signing in, you might want to check if there are any issues with your account or if the application needs to be reinstalled.
