unable to save to Offline Folder from Office 365 Desktop products

We are having an issue with Offline Folders disconnecting when saving from Office 365 2016 products. I'll use Word 2016 as the example. Word is version 1708 Build 8431.2250, Windows 10 pro is the OS, Version 1709 build 16299.431 Server is 2008r2 all updates. This seems to have started with April's Office updates.
Steps to reproduce: Open an explorer window to a location set to "always available offline", then open an existing word doc or create a new word doc an save it to the same Offline Folder synced with Sync Center that you opened in explorer, you should see the status go to offline. I've been able to reproduce this at will on multiple computers. The folder will automatically go back online in a few minutes.
I am able to drag and drop to the offline folder with no issues, and I am able to save from Adobe Acrobat Pro and Bluebeam among others with no issue. I only have a problem with Microsoft Office products.
Any help is appreciated.

Unfortunately the issue is still on going, I have a support ticket open with MS that has gone no where.

why are you saving it to the offline folder if you are online? Or are you opening the file from the share, disconnecting the nic and then saving the file?

When the user is in the office and connected to the LAN, he saves an MS Office document to a synced folder, that's when the folder goes offline. After about a minute or two, the folder will go back online. Drag and drop works fine, adobe products work fine. It is only happening on Office 2016 products. I can easily reproduce the issue on any of my windows 10 machines with office 2016.

when you say synced folder is this a onedrive4business folder on the computer?

This is Offline folder synced with a windows server. If you right click on a server folder there is an option to "always available offline". That is how these are synced
