Hi Team,
We are using MAPI to connect to office 365 mailboxes. While retrieving the mailbox content through MAPI call OpenMsgStore we are getting error 'Error in MAPI section: 0x80040111. Details: The information store could not be opened'.
On office 365 tenant, modern authentication is enabled.
Can anyone please confirm if MAPI call OpenMsgStore works with Modern Authentication or not ?
