FYI Def permissions related.
Something to do with having partial mailbox access. If I view an account who has not had Adaxes added as a mailbox adminthere is no UI corruption, but if I view an account that has we get the issue.
In this event, even though we have granted mailbox access we get the following error under the Delegation tab (which strangely we don't get when the service account hasn;t been granted the access rights):-
"Failed to get mailbox rights. Some or all identity references could not be translated."
I'm checking whether this is because there are references to our parent domain in the delegation list (where Adaxes is not permissioned), and/or something else.
To help track down any issues, can you confirm the minimal rights that the Adaxes service account needs in Exchange? Currently we are granting full access on a per-mailbox basis during the testing, and the Adaxes service account is also a member of the Exchange organisation admins account.
Many Thanks
