Hi,
Anyone using EWS faced this issue before?
Failed to get mailbox session - ErrorNonExistentMailbox
This is for archive mailbox.
The Following checks have been made:
Archive Mailbox exists in OWA (Outlook Web Application)
Mailbox username is added to Global Address List
Mailbox has adequate License
The above are the most common recommendation I could gather from articles online, have already tried.

@Vasil Michev Many Thanks for that insight!
Was there any successful resolution to that?
