Issue with saving files to redirected drives in terminal server

Hi all,

I have 2 Terminal servers with different reader versions, 1 has Adobe reader XI and the other has Acrobat Reader DC version 2019.010.20098

When I login to the server with XI and I want to save a file from the program to a redirected drive I have no problems. However, when I try the same on the server with DC I get this alert: "The document could not be saved, access denied".

On the problematic server I am able to save files to that location by copying and pasting or even from office apps saving new \ existing files to the redirected location.

Also, these servers are used to work with SAP. On the problematic server, when a user tries to save a file from SAP to the redirected drive it gets the alert about "disk used for temporary files is full".

Any help would be appreciated.
