Why does Microsoft say I need admin approval?

Your organization lets only approved apps read company mail, so Microsoft stops the sign-in. Ask your IT admin to approve Inbox Triage in Microsoft Entra, then choose Connect on the inbox again.

What happened?

Microsoft 365 organizations decide whether users may allow apps to reach their mail. If yours does not, Microsoft shows a "Need admin approval" page, and nothing is connected. If you go back to Inbox Triage, it says "You did not allow access at Microsoft, so nothing was connected" (or "Microsoft did not finish signing you in"), with Microsoft's details underneath.

What do I ask my admin for?

Ask them to approve Inbox Triage for your account or organization. It asks for these permissions:

  • Mail.ReadWrite: read and change your mail, such as drafts, archive, and junk.
  • Mail.Send: send a draft, after you approve it or under Send on my behalf if you turned it on.
  • User.Read: read your name and email address.
  • offline_access: stay signed in so syncing keeps working.

Point them at our Security and Privacy pages.

What do I do after approval?

Open Inboxes and choose Connect on the inbox again.

Connecting a Microsoft 365 mailbox over IMAP with a password is not a way around this. Microsoft has turned off password sign-in for IMAP on Microsoft 365.
