Just an fyi more than a question.
I've been using Pro for almost 3 years now. I have always kept my projects on a network storage drive and worked off the NAS as well.
In the past, I have been able to add a folder connection to my project by right click on folders in the catalog tab and navigate to the folder I want to add (\\networkdrive\projects\project\data). It's worked that way for 3 years. Today when I started a new project and went to add folders in the usual manner, I get a popup "network error cannot access \\networkdrive\projects\project\data". Same results if I use the windoes mapped drive location.
Checked all permissions. Nothing has changed. ArcMap 10.6.1 has no issues connecting to folders on the same drive. Did lots of searching. No answers.
When reviewing documentation on adding folder connections, one of the options is to drag and drop from file explorer to the catalog tab. I thought no way will this work. But it did and I am glad but it leaves me scratching my head! 🙄
We have the same problem with our users. Coming from 2.7.3 to version 2.8 gives error: Network Error cannot access R:\ArcGIS\MyGISData. Reset users to 2.7.3 and they can get back to their share. Reported to ESRI NL but they have not been able to reproduce it yet.
(R is also a NAS share, underlying path is \\lnv.intern\home\H\name)
Well, version 2.7 appeared to work in that it would connect to the folders on the network storage through the right click on folders. But, any edits that I do to a shape file corrupt the file. I can fix them using shape file checker but that isn't efficient!
I received a feedback from ESRI NL, the translation below from Dutch, seems that there may be a bug in 2.8. To be continued.
Thank you for your additional information.
You were the first to ask us the question, but you are no longer the only one.
I'm going to pass the case on to my American colleagues, as I can't reproduce it myself (we don't have a network drive available this way).
