Anyone faced this issue with archive mailbox?

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.

  • The only time we've have run into issues with archive mailboxes and EWS is when the auto-expanding archives functionality is used.

        Not sure if there was any, as EWS seems to have limited support for auto-expanding archives, But again, that was specific for them, "regular" archives should be fine.
