Using the New Outlook for Mac for personal email and calendar
The most likely causes in this scenario are:
- A hidden inbox rule or forwarding setting left behind after the compromise Attackers commonly create rules that delete, move, or redirect incoming mail. Since mail is missing in Outlook on the web as well, this points to a mailbox-level setting rather than an iPhone or Mac sync issue.
- A temporary inbound restriction after suspicious activity After an account is compromised and used to send unauthorized mail, incoming delivery can be temporarily affected even after the password is changed.
- A mailbox setting that is moving mail out of view
In Outlook.com, also check:
- the Other tab
- whether Filter > Sort > Date needs to be restored
- whether any email rules are still preventing messages from appearing
- Junk or blocked handling is not the only place mail can be diverted Even if Inbox, Junk Email, Deleted Items, Archive, blocked senders, and storage all look normal, mail can still be redirected by rules or forwarding.
Because the issue happens in Outlook on the web, the strongest next checks are:
- Re-check Mail > Rules and remove anything unfamiliar, especially rules that delete messages, move them to another folder, or forward mail.
- Re-check Mail > Forwarding and confirm forwarding is off. If that page still will not open, that remains a strong indicator to resolve because forwarding is a known cause of missing incoming mail after compromise.
- Check the Other tab, Junk Email settings, and confirm there are no filters or sort settings hiding messages.
- If no suspicious rules or forwarding are found, allow some time for the account to settle after the security event. Community guidance in similar cases notes this can take up to 48 hours.
- If mail still does not arrive, use Outlook.com support from the Help menu or the support contact option, because a service-side restriction may still be in place and cannot be cleared from mailbox settings alone.
