Thanks for the info. Now that I know what's going on, we can take a course of action to find out where it may be coming from and put a stop to it.
Does anyone have any suggestions about my other issue? I have several users whose mailboxes are growing in size every time they logon. The actual main.mbx file is small (i.e. 55 KB), but in IMail Admin it shows it as being 29.8 MB. They next they login it is 31.1 MB, etc., etc. you get the picture. This puts them way over the allotment they are give and they cannot receive any more mail. The average growth per login is about 1.3 MB. Does anyone know why this is happening? Why would their mailbox be so grossly misrepresented and how can I fix this? I have already experimented with a few things by duplicating a problem account and playing around Even if I put in a empty mailbox file, the indicator still shows the overblown amount. I am getting more reports of this by the minute. Anyone have any insight into this? Thanks. Ron -----Original Message----- From: R.
