The Office Suite is powerful enough to support both Windows 10 and Mac users, but that does not mean that it does not come with its fair share of problems.

A while ago, Microsoft had released an official web page with the most known issues concerning Office and Windows 10 and has provided a couple of fixes for the aforementioned.

We’ve decided to add some more to the list. So without further ado, here are some useful methods to solve Microsoft Office 365 known issues.

How to fix common Office 365 issues and errors

I. Microsoft Office 365 login issues

1. Check your credentials and try changing the login format

Also, the issue might come from a Generic Credential with a Persistence set to Session. So, you will need to find the problematic credential and delete it.

Here’s how to do that:

  • Press Windows Key + S and enter the Control Panel.
  • Select the Credential Manager.
    Locate the problematic credentials and recreate them.

2. Use a third-party software
