I am the Email Admininstrator for a company with a single Exchange 2003 SP2 server that houses approximately 300 mailboxes on it; our clients access their email with Outlook 2003 from their desktops.
A number of our users have Cached Exchange Mode loaded in their Outlook profiles.
We normally set a mailbox cap in Active Directory to force our users to keep their mailboxes under control; however, a growing confusion is occurring regarding apparent discrepancies between the folder sizes as reported in the Mailbox Cleanup Wizard; i.e., the folder sizes differ between the local folders and the server folders (which I suppose is to be expected, though I'm not sure why); the bigger confusion, however, appears to be which set of folder sizes the user should "go" by in determining which folders should be pared back via archiving and/or deleting of data - the local folder sizes or the server folder sizes, in light of the fact that the 2 are synchronizing with each other. Logic would suggest the server-side size of the mailbox would be triggering the mailbox size warnings, but I'm not sure that Outlook isn't reporting information back to the Exchange Server that might be launching the warning messages based on the local file data sizes. I just would like to be sure so that I am not leading my users astray on this.
Could someone provide me with a brief explanation or point me to a possible source of information on this? I've been searching around but haven't found anything that addresses this issue. Please advise; thanks.
