This article explains how to resolve the error in Salesforce Outlook Integration where a user sees the message: "We encountered a problem. Contact your administrator and mention that your Exchange account is already associated with another Salesforce login" when attempting to log in. This error occurs when the Exchange account is already connected to a different Salesforce user in the Outlook Integration user mapping.
The following steps help an administrator identify which Salesforce user has already connected to the Exchange account, so the duplicate mapping can be removed and the correct user can connect.
