When I send an email from my GroupWise 22.214.171.124 server to my Exchange 2000 server (different domain), the Exchange server shows the from address very funky (for lack of a better word). In Outlook 2002, the From shows this: "Eric Lanyon" <elanyon@xxxxxxx> [[rfi.com]];.elanyon] If I hit reply, it shows the same thing in the To field. If I send the email, the Exchange box comes back with the following header: From: System Administrator Sent: Date and Time To: '"Eric Lanyon" <elanyon@xxxxxxx>' Subject: Undeliverable The following recipient(s) could not be reached: "'Eric Lanyon" <elanyon@xxxxxxx>' on date and time stamp. The email address could not be found <mail.exchangedomain.com #5.1.0> If I manually enter my GW address, elanyon@xxxxxxx, it works perfectly in Outlook. Not sure if this is an Exchange/Outlook problem or a GW problem. Any ideas?
