I am not recieving any emails

Work through these checks in order to restore mail delivery:

1. Confirm internet and sign-in

• Open a browser and verify general internet access.
• Sign in directly to the mailbox in a browser (for example Outlook.com or Outlook on the web) and check whether new messages appear there. If mail is visible in the browser but not in Outlook, the issue is with the Outlook client, not the account.

2. Check storage and account status (Outlook.com / Microsoft account)

• If using Outlook.com, verify that Microsoft cloud storage and mailbox are not full. When storage is full, no mail can be sent or received and messages sent to the account are bounced and unrecoverable. Use the mailbox storage page referenced in the documentation to see what is taking up space and free it if needed.
• If sign-in has been unusual recently, the account might be temporarily blocked. Use the unblock flow described in the Outlook.com article to restore normal operation.

3. Look for messages in other folders or views

• In Outlook.com:
  • Check the Other tab (if Focused Inbox is enabled) to ensure messages are not being sorted there.
  • Check the Junk Email folder and, if legitimate messages are found, right‑click and choose Mark as not junk to move them back to Inbox.
  • Make sure the message list is sorted by Date (Filter → Sort → Date) so that new messages are not hidden by an unusual sort.
• In Outlook desktop:
  • Confirm the Inbox view is not filtered to an old date range (for example, a Favorites Inbox showing only earlier days), and clear any filters so that “Today” and the latest items are visible.

4. Check rules, forwarding, and blocked senders

• In Outlook.com or Outlook on the web:
  • Review Junk Email settings and the Blocked senders list; remove any sender or domain that should be allowed.
  • Check for rules that move or delete incoming mail, including rules that might divert messages to unexpected folders (such as RSS feeds). Disable or delete any rule that redirects normal mail.
  • Check whether email forwarding is enabled and, if so, confirm it is configured correctly or turn it off if not needed.
• In Outlook desktop (such as Outlook 2016):
  • On Home → Junk → Junk Email Options → Blocked Senders, remove any legitimate senders or domains.

5. Verify connection and sync in Outlook client

• In Outlook for Windows:
  • Ensure the client is connected to the internet (no “Working Offline” or “Disconnected” status).
  • Use the Sync button on the View tab to force a manual sync and watch the status message at the bottom of the message list.
• If only one device is affected, and the mailbox works elsewhere, remove the device partnership from the mailbox as described in the Outlook.com sync guidance, then re-add the account on that device.

6. Check account configuration (desktop or Mac clients)

• In Outlook for Mac or other POP/IMAP setups:
  • Confirm the account settings (email address, username, password, server names, ports, SSL) match the provider’s requirements.
  • If the account previously worked and recently stopped, verify that the incoming server and port are still correct; some providers require specific POP/IMAP ports.
  • If using a third‑party provider, ensure it supports modern authentication and IMAP for use with Outlook; if POP/IMAP are enabled and causing issues with a connected app, follow the provider’s guidance to adjust or disable them.

7. Repair Outlook or profile if the client is corrupt

• In classic Outlook for Windows:
  • Run an Office repair as described in the Office repair article.
  • If issues persist, repair the Outlook profile or create a new one using the profile repair guidance.
  • If add‑ins might be interfering, start Outlook in safe mode (outlook.exe /safe). If mail flows correctly in safe mode, create a new profile and disable problematic add‑ins.

If, after these steps, messages still do not arrive anywhere (web and all clients), contact the email provider or administrator to confirm the mailbox is active and not blocked or removed.
