I wonder if others have this same "feature?" I can duplicate this bug on both my desktop and notebook, so it appears to me to be a bug.
This involves Exchange Server 5.5 with public folders. Right-click on a public folder you are an owner on and then click the Permissions tab then OK. Repeat about 4-6 times. Outlook complains it is out of memory, then you get a dialog box where it says that Outlook has had an error and needs to be restarted.
It will let you determine if you want to restart or just shut down with a check box. Any draft open, etc. is gone!
