Hi
The reason behind this error could be your Outlook.com updating to Outlook Mail. It means the Outlook.com account migrated to the new servers on Office 365.
Thus, you need to re-create your account as the old profile is not supported by Outlook Mail. Use auto account setup to re-add the account to the profile. This will connect using Exchange.
Note: Because Outlook 2007 doesn’t support multiple Exchange accounts in a profile, any users with Outlook.com and an existing Exchange account in the current profile will need to use two profiles.
Now you don’t need the connector and you can uninstall it from the Control Panel -> Programs and Features.
Hope this solves the problem
Thanks & Regards
Henry
