Office 365 Migration Error
We saw this error after the migration had processed around 50% of the migration batch, So we are using the same migration account, so how can it fail to logon ?
The error is a little misleading.
We tracked this error down to an issue with Server 2008 or higher where the number of AD logons per account is limited.
To resolve this issue:
edit the following registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS
