The Document Routing Agent requires a manual refresh of it's Azure service token every 90 days to enable its connection to D365 F&O. This is regardless of if the DRA is run as an application or as a service.

If the DRA is ran as a service and Azure service token expires, it will continually attempt to connect to re-authenticate and generate endless files in the user's INetCache\IE folder. Consequently all extra space on the machine where the DRA is installed can and will be consumed if left unchecked.

Two possible solutions:

-Allow the Azure service token to be refreshed automatically or at least via script instead of manually through the application (preferred solution)

-Limit the DRA's attempts to re-authentication when the token is expired. If a manual refresh is required, the DRA shouldn't be attempting to connect endlessly.
