Hotmail, Outlook, Office365, or Live.com Slow Response Times

If you have an account hosted by Microsoft, such as Hotmail, Outlook, Office, or Live.com, and Postbox is taking a long time to load messages (showing you a spinner), this is because Microsoft recently changed the name of their incoming server to outlook.office365.com.

To fix this, update your incoming server name in account settings.

macOS

  1. Go to Preferences > Accounts
  2. Select the account that is experiencing the problem
  3. Set Incoming Server to: outlook.office365.com
  4. Close the Preferences window

Windows

  1. Go to Tools > Options > Accounts
  2. Select the account that is experiencing the problem
  3. Set Incoming Server to: outlook.office365.com
  4. Click OK
