Remove and re-add your Exchange credentials:
1. Close Microsoft Outlook.
2. Open Control Panel.
3. Select Credential Manager.
4. Select Windows Credentials.
5. Remove any existing credentials relating to your Exchange mailbox.
6. Select Add a Windows credential.
7. In Internet or network address, enter: *.outitgoes.com
8. In User name, enter your full email address.
9. In Password, enter your Exchange mailbox password.
10. Select OK.
11. Select Add a Windows credential again.
12. In Internet or network address, enter: *.exchange-outitgoes.com
13. In User name, enter your full email address.
14. In Password, enter your Exchange mailbox password.
15. Select OK.
16. Open Microsoft Outlook and try to connect to your mailbox again.
