Starting about three months ago, Office 365 is requiring me to activate the Word or Excel document that I am working on. It has become frustrating and annoying. I have Googled help on the internet, but the responses have been complex, and not working for some people. I have both gmail and msn internet accounts, and I don't know whether that is confusing the Office login.

I went to Keychain Access, Login, Passwords, and found Microsoft Office Credential.

I hit Get Info, Show Passwords, and saw the letter M. What is this all about? I changed the password to something that I use frequently, but don't know whether this will make a difference or not.
