Connecting to ms exchange shared mailbox via imaps using apache camel fails with error AUTHENTICATE failed

Were running Apache Camel (2.25.2) and connecting to mailboxes via imaps. Our configuration works but not for shared mailboxes. Connect string we use to connect "normal" mailbox:

imaps://srv.Domain:993?username=UserMb@Domain&password=Pass&folderName=Inbox&consumer.delay=60000&copyTo=done&delete=true&mail.imap.starttls.enable=true&mapMailMessage=true

This works fine. Camel is able to read/copy etc. mails from inbox and other folders. For connecting to shared mailbox we use same string only adjusting username=.

For example:

imaps://srv.Domain:993?username=UserMb@Domain\UserMb2&password=Pass&folderName=Inbox&...

.. and it is not working.

Ive already tried Domain\UserMb\UserMb2 or UserMb@Domain\UserMb2@Domain or UserMb@Domain\UserMb2 etc. and also

imaps://UserMb@Domain:[email protected]:993?folderName=Inbox...

All works fine for UserMb until shared mailbox UserMb2 is added.

Ive also rechecked in Thunderbird, mapping UserMb2 as shared mailbox using UserMb@Domain\UserMb2@Domain which works fine.

Ive already read something similiar here Possible to connect with a Microsoft Exchange shared mailbox via service account using JavaMail and Apache Camel Mail (IMAP)? but without a correct solution for us.

Does anyone have an idea? Thanks!
