I think it had something to do with secondary smtp addresses and which one was set as reply address but don't quote me???
-----Original Message----- From: dave mcnulty [mailto:[EMAIL PROTECTED]] Sent: Friday, April 19, 2002 12:56 PM To: MS-Exchange Admin Issues Subject: Instant Messaging Helo I have installed IM in a win2k domain using one exchange 2k. The IM clients are failing to authenticate - the error message when logging onto the im server the client states that the "user does not have permission to use the specified email address. Please supply an email address and logon credentials for that address." I have the appropriate SRV record in DNS to allow users to logon using [EMAIL PROTECTED] and have given the IM server permission to handle logons - in fact i have followed technet and e2k resource kit advice exactly (maybe that's where i went wrong :-) ). Has anyone come across this before? Or can anyone point me to a URL?
