executing configuration script task failed with the following error:
Method add_user calling failed. Reason:SubscriptionOutOfSeatFault Method: SetUserSubscriptions
Office 365 subscription is not synced with MOP. It means that most probably customer created users and assigned licenses to them directly in MOP. As a result, OA does not know anything about this and 'thinks' that there are still unassigned licenses.
SetUserSubscriptions means that OA tries to assign license to the user and fails. How to troubleshoot such situation:
Check MOP side and OA side - compare users having assigned/unassigned licenses and try to manually sync subscription with MOP by deleting/unassigning license from users in MOP
Check if there are 'Deleted' users in MOP with licenses assigned. Users, marked as 'Deleted' do not take part in synchronization process
- Try to run synchronization script (cancel failed 'executing' task and corresponding 'finalizing' task before you start).
Real life example:
- license was assigned to user A in MOP, license limit is 1 in the subscription
- sync was not done yet, and the same license was assigned to user B via OA CCP
- task for assigning license to the user B failed with
The solution for such case will be to deassign license from user A via MOP.
