I am migrating from our current mailserver to Exchange365 and have been testing Kayako mail queues with exchange. I can successfully send/receive mail via a full Exchange account, but have problems with a shared Exchange mailbox. Using the credentials: firstname.lastname@example.org\shared_account_alias and the password: user_password via SSL/TLS will send & receive mail from the exchange shared account using Thunderbird, but using identical credentials with Kayako does not collect mail. The Kayako verify connection test passes all tests, but reports 0 emails (I verified there are [unread] emails in the account). To save my sanity, has anyone configured Kayako to work with exchange365 shared mailboxes successfully? Thanks in advance!
