I have a wierd one here. We have two email domains on one Exchange server. The folks who have an address in both domains need to be able to send messages so that they are reflected as being from a particualr domain. To accomplish this, we set up a seperate account for each of them for their email in the second domain, set up their outlook client for their primary address, and gave them the mailbox of the second address to be able to view there. They were made delegates of the second box with owner rights to it, and then we enabled the "from" field in the Outlook message composition window. This has worked flawlessly to this point. The user simply composes the message and puts the second address in the "from" field. Ok, that's the background. I just had to give one of these second addresses to a new user. I set it up the same as all the others. But when she tried to send a message putting ehr second address in the "from" field, the server kicks back an undeliverable message, saying she doesn't hav epermission to send to the recipient. It gets worse - I logged into a test machine in my lab as her, and set up the email client the same way, and it works fine. There's something screwey on her workstation, but I'll be darned if I can figure out what it is.
