    OK, if you disable an AD user which is synced to O365, the O365 user will then be blocked from signing in too.

     

    If you sync an AD account to O365, then move the AD account to an OU which is not synced, the O365 account will be deleted on the next scheduled sync pass.  The result of this is that the O365 account will be moved from the Active Users folder to the Deleted Users folder.  It will remain recoverable for 30 days, then it will be permanently purged and not recoverable.

     

    So no, neither of these are options for you i'm afraid.

     

    If you sync the disabled users OU, then the O365 user will not be deleted at the next sync,  but would of course still be blocked from signing in.
