Modifying existing Users with Office 365 Connector


i have the folloewing Problem:
I used to have UCS (4.1-5) connected to Office365 via a Delta sync and the AD-Connector.

After a failed Upgrade to a newer Version, i had to restore my installation from an Backup. This led to my Delta Sync not working anymore.
I upgraded my restored System to Version 4.4-5 and i use The Office 365 Connector now, unfortunately i can not alter the already existing Users in AD.
Following error is in the listener.log

Hello @ppwieseckel,

UCS 4.1 is not maintained anymore. Please consider an upgrade to UCS 4.4 first. There have been changes in the app in the meantime because of API changes at Microsoft and they are not provided for UCS 4.1.

Best regards
