We are a Exchange 2000 site, running Outlook XP client.

Some users can invoke a rule that enables server based
replies. Many others can not - getting the ubiquitous and
utterly useless error message "you don't have appropriate
permission to perform this operation".

The only KBA I can find is 316536 which says "Exchange
Server cannot perform the "Have server reply with
specific message" Inbox rule if you change the mailbox
that is indicated in the From box" and offers two
completely useless "workarounds" - ie have a client based
rule or acquire third party software.

If the rule breaks because the "From" field is changed,
then how do you "unchange" this field??

Can anyone offer any advice, or is this just buggy
software?

regards...
