The MDS add in for Excel will not allow me to test the connection or even connect to the MDS server when I launch Excel. I need to disable the add in and re-enable it in order for it to work. I am running add in version 14.0.3024.368. I had the same issue with the 303 release as well. Office Version is 16.0.10325.20082.
I enabled logging with the add in; however, the log is blank and does not give me any information when clicking connect.
I have confirmed that the add in is set to load when Excel is launched. I have also been able to replicate this behavior on multiple computers including ones that are running Office version 15.0.4569.1506.
Any assistance on this is appreciated.
