I'm writing an ASP page that is going to run on an IIS server (versions 4 and 5). This ASP page needs to be able to look up the SMTP address(es) for a specified mailbox alias on Exchange 5.5 and 2000. I wrote some code to do it using LDAP and Active Directory for Exchange 2000 but I'm struggling to find a way to do it in Exchange 5.5. Anyone do this before or have any ideas? Also, is there a way to programmatically determine if I'm connected to an Exchange 2000 server or an Exchange 5.5 server? Thanks, Mike _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
