When running the MailEnable Diagnostic Report the FAIL error of "IME_ADMIN is not a member of IIS_WPG group" error shows.
The reason that the IME_ADMIN error is coming up is due to a problem with the MSC interface. If you run the Diagnostic Report outside of the ME Admin MMC it works (Start->Run->MEDIAG). So the issue is not that the error exists but that the Diagnostic Report within the ME Admin MMC is being affected by the way it does the lookup.
Run the Diagnostic Report outside of the ME Admin MMC.
The main thing with this error is to firstly make sure that the IME_ADMIN account is a member of the IIS_WPG group of your machine. If the group does contain the user then this error can be ignored.
There is an internal issue within the MailEnable issue register for this problem to be reviewed and resolved.
