365 authentication/login issues
Just started working at a tiny firm. I started using 365 there with one login before someone realized my account's email address was the same as a prior employee's email, which was causing issues with me receiving a lot of junk mail and confusion over communications externally. The solution to this issue was for them to change my login and email address.
Since this happened, I can't log into MS 365 apps on my PC desktop. I can access the web apps just fine, with the exception that Word and Excel are operating as "view only" apps. The error message when I go to log in reads something like
"Another account from your organization is already signed in" and prevents me from going any further.
I can access the office's One Drive from the web but not sure if desktop is accessible there either. For some reason Outlook works just fine in both formats.
Does anyone know how to fix this? My next option is to like hire my own personal IT asst. to sort this out. It's been 4 days of troubleshooting this at a new job while on-boarding and I just really need it to work.
If I just buy my own 365 to avoid having to deal with theirs, could this theoretically solve the problem? Or would the new Outlook and One Drive potentially overwrite the 2 apps I can actually use and make this worse?
Many thanks
