I read that Exchange 2016 does not support CDO-MAPI. But if I am using an Outlook-2013-MAPI-profile, will this still work with mfcmapi?
A first connection test is successful, but if I want to open other mailboxes via GAL, I get
Code: MAPI_E_CALL_FAILED == 0x80004005
Function OpenOtherUsersMailboxFromGal( lpMAPISession, lpAddrBook, &lpMailboxMDB)
ExtendedRights "Receive-As" were set (it worked on Exchange 2013).
Now I am not sure if this is still a misconfiguration or If Exchange 2016 does not support this feature.
