Original product version:   Team Foundation Server
Original KB number:   3192409

Symptoms

You discover that the Team Foundation Server 2015 Office add-in doesn't work because it's not signed by a trusted publisher. This issue occurs when the following conditions are true:

  • You're running a 32-bit version of Office on a 64-bit computer.

  • You have a version of Team Foundation Server that's earlier than Team Foundation Server 2015 Update 3.

  • In your Office settings, the Required Application Add-ins to be signed by a Trusted Publisher check box is selected under File -> Options -> Trust Center -> Options.

Cause

This issue occurs if there are quotation marks in the add-in's Location field. This prevents Office from verifying the publisher. To confirm that this is the cause of your problem, go to File -> Options -> Add-ins, select the Team Foundation Add-in, and then view the Location field to see whether the location path is inside quotation marks.

  3. Right-click the (Default) entry, click Modify, and then delete the quotation marks at the beginning and end of the value in the Data column.
