Microsoft 365 error 7q6ch , can't login to my microsoft account
Microsoft 365 for business account, getting a microsoft popup box everytime I open office to login. I enter my email address and the next screen is always an error "7q6ch" . I can login to office.com no problem. This error will not go away no matter what I do and here's what've done-
removed all microsoft credentials, logged out of microsoft account, removed all accounts in settings, signed out of office, rand scannow, ran the fixes to delete the folders in app data, online repair, quick repair, ran the cmd promp and powershell fix, made a new profile, I uninstalled and reinstalled office, keep getting this popup.
The only option I'm seeing is to wipe my computer which I really don't want to do. It's a windows 11 pro laptop I downloaded the office setup file from my office account and it's up to date. I believe this stems from microsoft making me enter an account in order to setup my computer and since it doesn't allow work email addresses I had to use my personal account which then logs in to app automatically and the computer get confused. I need help please, any suggestion or fixes are appreciated, thanks

I would not wipe Windows. This pattern points more toward the Windows Web Account Manager sign-in component than the personal Microsoft account used to set up Windows.
First, open Get Help, search for "sign in to Microsoft Office," and run the Microsoft 365 sign-in troubleshooter.
Then open PowerShell as administrator and run:
if (-not (Get-AppxPackage Microsoft.AAD.BrokerPlugin)) {
Add-AppxPackage -Register "$env:windir\SystemApps\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\AppxManifest.xml" -DisableDevelopmentMode -ForceApplicationShutdown
}Get-AppxPackage Microsoft.AAD.BrokerPlugin
This checks and repairs the Microsoft Entra WAM package used by work accounts. Restart Windows afterward.
If the command returns an error or the issue remains, have your Microsoft 365 administrator review the failed sign-in in Microsoft Entra sign-in logs and confirm that the account has a license that includes the desktop Office apps.
I would not disable WAM or Modern Authentication as a workaround, since Microsoft does not recommend that configuration.
Same problem here with one of my PC. Hopefully Microsoft will fix it. Thanks for reporting it, I will not try all your steps for nothing.
