Inboxed + Outlook and Microsoft 365
Connect Microsoft 365 mailboxes over SMTP and IMAP; Microsoft sign-in through Graph is built and waiting on the server’s Microsoft app.
Microsoft 365 mailboxes connect over SMTP (smtp.office365.com:587) and IMAP (outlook.office365.com:993). Many tenants turn SMTP AUTH off by default, so an admin may need to allow it for the mailbox.
Microsoft sign-in is built too: it sends through Microsoft Graph with Mail.Send and Mail.ReadWrite, and appears once the server has a Microsoft app.
What you can do
- Send campaigns from Microsoft 365 addresses
- Bring replies into the team inbox
- Move warmup emails out of Junk
Set it up in 3 steps
- Ask your Microsoft 365 admin to allow SMTP AUTH for the mailbox if it’s off.
- In Inboxed, open Mailboxes → Any other provider and enter smtp.office365.com:587 and outlook.office365.com:993.
- Inboxed tests both logins and starts warmup.
