Good morning. I work in a group that frequently uses SharePoint 365 libraries and favor accessing materials through Windows Explorer (rather than navigating through the Internet Explorer webpage links). We are able to map network drives to specific SharePoint 365 folders but are constantly forced to "re-establish" connection with the SharePoint site because the mapped connection breaks. The workaround is to go into SharePoint, access the library, click "Open in Explorer", click several layers into the folders and then the mapped drive will work again. It's a major pain point... any thoughts on what we can do to resolve?
There are some third party tools that can help with this, but the reality is that this is working "as designed". User cookies expire periodically and lock the users out until they are refreshed.
There is some PowerShell that can be run to help, but to be honest, I haven't seen it make much difference.

I believe the general guidance is to use the next gen OneDrive for Business sync client to sync the content down to the local machine. Using the NGSC, you can selective sync folders you want so you don't have to pull down the entire structure.
