Windows 10: Office 365 sign in issue

The first time it happened was yesterday. One User at the office had purchased a new laptop and I loaded our company Office 365 on it using their company email account that the license is tied to. They later added their Gmail account to Outlook and I think this is where the problem started.

They were having many of the same issues in this thread and when checking i happened to notice that under "File/Office Account" instead of showing their Business email, it showed their Gmail account. All of their problems disappeared when I logged them out and back in using the correct account for the license tied to their copy of Office 365.

I do not know how this happened in the first place. They can still access their Gmail in Outlook and they deny chaning anything other than simply adding their Gmail account.

I checked some other systems and found several that showed the users not signed in at all to any Office Account. Yet these people were not having any problems to speak of. Is this some new setting for Office that if never setup in the first place can continue to work with no account configured and only presents problems if the wrong account is used?

On that same topic. On new systems that come 'pre-loaded' with Free Trials for Office 365 Home, should I uninstall the trial to acoid someone accidentally clicking it after they already have the Small Business Version Installed?

product key for office 365 please

Hi Kim, Office 365 generally does not come with a Product Key, it is locked to your Microsoft Account . . .

If you need to reinstall Office 365:

Go to Office 365 Login | Microsoft Office and if you're not already signed in, select Sign in.

Sign in with the account you associated with this version of Office.

On the Office home page, select Install Office - Install

If you are experincing another issue, please let me know . . .

 

Windows 10 Profile File Corruption

Windows Ticket # 1416827528 / Office 356 Ticket #7610400 | A few weeks ago, suddenly, Windows 10 failed to load a BSOD appeared with error message "Unexpected Kernel Mode Trap", then restart. this cycle continued until the computer was powered down.

Working with the Windows team the computer became stable but Office 365 had disappeared. Windows team recommended that I contact the Office 365 team. After numerous Office 365 uninstalls & installs, functionality returned but sign-in would not occur, the
latest Office 365 techie (a very nice person) determined that the Windows 10 Profile had become corrupted & proceeded to help setup a different Profile & Office 365 sign-in completed. Now, Office 365 will not load in either Profiles & the problem is not solved.
Should I uninstall & reinstall Windows 10 to solve the issue?
