A few of my AD 2003 user permission on SELF keep missing even if I have set it over and over again via the AD user and computer console. The same goes to "allow inheritable permission" check box, it would go unchecked again and again ....
As u can see in the attached picture, I have actually checked the "send as", "receive as" and "read account restriction" permission 1 hour before this, everything seems ok when I test sending and receiving emails for that user. However the permissions will go missing after 1 hour or so. The same goes to "allow inheritable permission" check box
I earlier thought it could be due to the level of administrator privilege I was using, like a lower level permission administrator cannot undo the settings done by a high level administrator. So tried using the Enterprise administrator, it didn’t help .. the permission got reset after 1-2 hrs.
