We have had a strange instance where a user has been enabled for Exchange Integration, but as soon as they are, Exchange Integration crashed. Errors in the logs give things like, potential memory leak and unable to establish connection to Exchange Integration server.
For info - the user has a double barrelled last name and their email contains a hyphen "-".
Found that no other users that are currently enabled have double barrelled last names in their email.
However, as soon as that user is disable on Exchange Integration again, all starts working again with no issues.
Tried to replicate the issue by enabling a user that does have an email in the same format (e.g. [email protected])
but Exchange seemed to work fine and reported no issues.
Has anyone else had anything like this where a single user was causing Exchange Integration to crash, but once disabled, all starts working fine again?
