We have a customer with hybrid environment with primary mailbox on-prem and archive in the cloud (o365).
Heretofore, we have been able to get a mailbox DN and server DN from EWS User Settings in order to pick up the info needed to establish a MAPI connection to an impersonated archive using the CreateStoreEntryID/OpenMsgStore mechanism.
But in this user environment, the DN values returned by EWS are both empty. The only relevant value is the smtp address of the could mailbox.
Is this expected?
Should the DN's be populated at the customer site config?
If these can be bona fide empty, how can we connect via MAPI?
Thank you very much.
