"Error in Import File Row 1: Failed to update User with username..." message in SendPro Enterprise

The error "Error in Import File Row 1: Failed to update User with username XXX. Unable to set property:User.UserName = XXX, from element: User.UserName.." occurs because the import file is case-sensitive.
Products affected: SendPro® Enterprise

Issue

When importing Users into SendPro Enterprise via the Supervisor App or the Data Management app, a message like the following appears:

"Error in Import File Row 1: Failed to update User with username XXX. Unable to set property:User.UserName = XXX, from element: User.UserName.."

Cause

The import file is case-sensitive. The UserName must match exactly as entered into SendPro Enterprise.

Resolution

Make sure that the UserNames in the import file match the UserNames in SendPro Enterprise exactly, including the case.
