outlook email.

For Outlook on Mac, these are the supported next steps for not receiving mail across Apple devices:

1. Check whether Outlook is offline.
   • In Outlook for Mac, open the Outlook menu.
   • Make sure Work Offline is not checked.
2. Verify the account connection.
   • Go to Tools > Accounts.
   • Select the account in the left pane.
   • For Exchange accounts, if the connection indicator is orange, there is a server connection problem.
   • If mail is available in Outlook on the web, that helps confirm whether the issue is with Outlook for Mac or the server connection.
3. Confirm account credentials and settings.
   • In Tools > Accounts, select the account.
   • Verify the email address, user name, and password.
   • If the password was changed recently, update it in Outlook.
   • Some accounts require special settings such as SSL or non-default ports.
4. If the account is POP or IMAP, check outgoing server authentication.
   • In Tools > Accounts, select the account.
   • Under Outgoing server, choose More Options.
   • Select the correct authentication type and enter credentials if required.
5. Check network-related causes.
   • Confirm the Mac has Internet access by opening websites in a browser.
   • If using a restricted network, the ISP or network firewall may block the SMTP server.
   • A proxy server may also be required on that network.
6. If this is an Exchange account and mail is not syncing, empty the Outlook cache for the affected folder.
   • Caution: This deletes any information not synchronized with the Exchange server, including contacts' mail certificates. Back up Outlook information first if needed.
   • Make sure the Mac is connected to the Exchange server.
   • In the navigation pane, Ctrl+click or right-click the Exchange folder.
   • Select Properties > General > Empty Cache.
   • Outlook will download the items again from the Exchange server.
7. Check whether mailbox or Microsoft cloud storage is full.
   • If storage is full, sending and receiving mail can stop.
8. Use Microsoft support contact options if self-service steps do not resolve it.
   • In Outlook.com, select Help, enter the issue, and if self-help does not solve it, go to Still need help? and select Yes.
   • To contact support in Outlook.com, sign-in is required.
