Dynamics CRM Online System Users name changed into #, #

Question

We are facing this issue in all our environments, when an employee left our company somehow his user profile in CRM is updated like below snip.

Domain name & Windows Live ID fields turn into weird GUID@domain.com and Name fields into #

Can this be controlled in someway in DirSync ? Disabling CRM users when AD users got disabled is expected behavior but this isn't.

We do have Pre-Create & Pre-Update plugins on System User entity, but nothing to do with Name fields obviously.

Any clue to solve this problem?

After a support ticket with MS & internal analysis, this was identified as an internal cleanup exercise by AD owners due to company policy. The data removal in AD account sync to Azure AD & in turn mess things in CRM like this.

We are running a scheduled cleanup job in our side now to restore the first & last name (composite field - full name), internal email address in systemuser from associated Mailbox record using SSIS/Kingswaysoft.
