As of yesterday afternoon (Jan 27, 2016), office Mac users could not use Outlook 2011 for Mac to access our Comcast Hosted Exchange server. Similar issue with Apple Mail on MacBooks, but NOT for iPhone Mail users. Windows users with Outlook 2010 had no problems. Browser-based Outlook Web Access users had no problems.

    • Method: User Name and Password
    • User name: sunetid@stanford.edu
    • Password: your SUNet ID password
    • Configure automatically: checked

  5. Click Add Account.
  6. A message displays asking whether you want to allow the Outlook autodiscover server to configure your settings. Check Always use my response for this server and click Allow.
  7. Your Exchange account settings display. Close this window.

  • Mac Mail would show “Account Error” which read “Unable to connect The server returned error: Connections to host mail.contoso.com on default ports failed.” The error is somewhat misleading as when you look at EWS logs on Exchange server, you see that the server rejected the request with HTTP error 400 which translated to “bad request”.
  • Jun 12, 2020 The existing Outlook Mac uses Exchange Web Services (EWS) which is being phased out. Outlook on Windows generally uses MAPI over HTTP, perhaps the nearest thing to a native Exchange protocol. Microsoft is not happy with either and for its 'modern' mail client in Windows 8 and Windows 10 it developed a new sync protocol.
  • The issue can be due to error in connection of Outlook with the correct Exchange Server. You should check it once to confirm if this is the issue. Follow this process: Go to Tools Accounts in your Outlook for Mac and check over the Exchange Account. If there is an orange indicator against the added Exchange account, then it means there is some issue with it.
