So we have installed the ArcGIS for Office 64bit on my laptop. Installed the Portal Resources for ArcGIS Enterprise on our internal ArcGIS Enterprise server hosting our internal Portal and installs worked fine. I can start Excel, log into my Portal as my self or my Admin account, Add a Map to Excel, go to the My Content drop down and select My Organization to list all our Portal layers. I then can only add certain layers that are listed and they may or may not display in the map window. If I can add a layer, and then go to add a second layer, the second layer will never display so basically I am stuck to only have one layer displayed. Working with Tech Support for over an hour resulted in them having no ideas as to what the issue is. Anyone have any thought/ideas/suggestions by chance? Anyone else run into this issue by chance?? Any help will be greatly appreciated. Thank you.
