This is a continuation of the Office 2019 Home & Business not updating problem. Now it updates fine (Now a 64-bit install vs previously 32-bit Office). But after a few hours, it will stop saving files to the network. Document not saved. SFC /scannow fixes it every time, but it can happen twice in a business day. Running CHKDSK /r now. Have run DISM twice already. This is the only user to ever have the problem. 20+ users all using the exact same server. 5 of them have the exact same version of Office 2019 (This is now the only 64-bit version) and exact same laptop. It doesn't matter if she connects wired or wireless. She does have offline files enabled on her personal drive. But it can be any mapped drive on any server will produce the same result. Local save does work.
