3. Stop third-party applications that access MAPISVC.inf file

The ‘Metered Connection Warning’ in Outlook issues can also be caused by third-party applications that access MAPISVC.inf and prevent Outlook from setting up the Account Manager.

To mitigate this situation, we need to stop the applications and processes that may be affecting MAPISVC.inf.

Use Process Monitor to see the processes that are accessing MAPISVC.inf. If a process displays a SHARING_VIOLATION on MAPISVC.inf, it indicates that the associated application is likely to be responsible for the issues. For instance, RepMgr.exe (C:\Program Files\Confer\RepMgr.exe) is an application that is known to cause these issues.

We have to stop this process if we see it in Process Monitor.
