ErrorImpersonationDenied

Domain: Exchange

Code: ErrorImpersonationDenied

Type: Configuration error (You are often able to resolve this type of error.)

Description: Impersonation denied. The connecting Exchange user does not have the “ApplicationImpersonation” role.

Possible solution: You must assign the “ApplicationImpersonation” role to the integration Exchange service account used for the integration.

If the error happens when integrating a service account, please make sure that the service account itself is within the impersonation scope since the validation of the service account is done by impersonating the service account itself.
