Office365 Migration
Hello, On Friday December 28th we started our Office365 tenant to tenant migration. On the old tenant we disabled dirsyn (Azure AD Connect) and then uninstalled the tool altogether from our on-pr...
- Yes, can imagine the frustration!
Let me know how the password reset on AD goes for an impacted user and if this resolves it. If not, here is the WAM override method which worked for another community user not too long back.

Let me know how that goes.

Hi,
I have seen very similar things to this when doing tenant mergers in a past role.
Are you using exactly the same domain in the new tenant? It would mean the credentials to log into the new tenant are exactly the same as the old (considering you are using AADConnect). The point is this may cause issues with the credential manager.
Have you considered, with an impacted user, flushing their credential manager on their Windows machine and then resetting their AD password so their login credentials to the new 365 tenant are different from previously? Would be good to hear how this goes.
Other than this, you disabled GPO but have you checked the impacted users hosts file (anything there?).

- Hello,
Yes same domain name from the old tenant to the new. We had to change the usernames on the old tenant in order to remove the domain name to move to the new tenant.
We have tried wiping out credential manager as well, however we will try it again. We've come across various forum threads regarding registry keys to disable the Windows 10 WAM (Web Account Manager)
We might have to try this as well. We're an organization of 120 and roughly 25 users having this ongoing issue. Very frustrating.- Yes, can imagine the frustration!

Best, Chris- Just so everyone knows, password reset worked.
Having users change even once character on their on prem AD account and allowing sync to finish resolved the issue.
Bizarre issue for sure.
Based on your description, those machines seem to be joined to Azure AD, which is where WAM starts playing its role. While great technology in theory, it's NOT intended to be used with multiple tenants on the same device and is known to cause all sorts of issues. So yes, disable WAM and test, just to be on the safe side.
