There are two methods to connect Azure mailboxes to a sequencer: OAuth and IMAP/SMTP.

We upload the mailboxes as IMAP/SMTP mailboxes to unsupported sequencers by default. They might be displayed with a generic email symbol 📧 rather than a Microsoft logo. That’s not an issue however, and you will have the same great deliverability because the sending path is identical to a mailbox connected via Microsoft OAuth.

If you want the mailboxes connected as Microsoft OAuth mailboxes, please reach out to your Deliverability Advisor to discuss options.
