PROBLEM
Users cannot access other users mailboxes anymore, although necessary entries had been made in the past under Configuration > Access Control.
One or more entries under Configuration > Access Control contain GUID like entries. For example: [6fd8bd7a5cb1724580e80aaa3436e94b] (deleted)

The debug log ..\Core\Debuglogs\AdaEngineADDSHostplugin2.log or DirectoryEngineAD.log shows logging as below referring to the very same GUID number as the one showing:
"IsUserInGroup[8ef97447a9fc324d9f1ca7ff15e665e9][6fd8bd7a5cb1724580e80aaa3436e94b]: >>"
"ERROR: IsUserInGroup: exception while enumerating user groups[There is no such object on the server.;]"
ENVIRONMENT
- GFI Archiver
- All supported environments
SOLUTION
- Open the web page
- Navigate to Configuration > Access Control
- Remove any entries which are displayed as [GUID] (deleted) within a column that refers to groups, for example: [6fd8bd7a5cb1724580e80aaa3436e94b] (deleted)
- Re-add any Access Control entries as desired (create new groups in Active Directory if need be)
CAUSE
Groups which had been configured under Configuration > Access Control have been deleted from the Active Directory.
