Azure AD Office 365 Your Password Has Expired

[DannyVLRS]

Started happening about a month ago users would change password after being prompted but the prompt keeps on returning. (Not happening to everyone but I'm unable to find a pattern)

Troubleshooting

We've logged out logged back in again restarted  etc

Access Work or School Account > Info > Sync

Company Portal > Setting > Sync

Reset the password myself via 365 admin Center

Check for updates > Check for updates

Provisioned with autopilot and we use intune everything cloud based

I believe the below has something to do with things not working

Have you checked in the azure portal the sign-ins logs for those users?

I believe the issue may have been the passwords not syncing correctly.

Password constraints on local and online are different which is why they wouldn't sync.

User password satisfied one constraint but not the other not a problem we could see so very hard to figure out

@FredG93 Nothing there Fred :(, I got a bit creative and removed and re-added the E5 licence but that didn't help either.
