FAQs About Outlook Not Receiving New Email

Why does an Outlook message remain in the Outbox?

A large attachment, offline mode, authentication failure, damaged message, or server limit can hold the item. Open the Outbox while offline, move the message to Drafts, reduce attachments, reconnect, and send a new test message.

How can I tell whether the problem is Outlook or the mail server?

Sign in to the provider's webmail and send a message to yourself. Compare that result with Outlook in safe mode or a new profile; this separates mailbox delivery from a local Outlook configuration problem.

Which Outlook setting should I check before recreating the profile?

Confirm Work Offline is off, review File > Account Settings > Account Settings, run Repair when available, and inspect rules, forwarding, focused inbox, junk, and mailbox storage before removing the profile.

What information should I capture for a persistent mail-flow problem?

Record sender, recipient, subject, UTC time, message trace or nondelivery report, provider, account type, and whether webmail succeeds. Administrators can use those details in Exchange message trace.
