Hi all We are running Exchange 5.5 Enterptise Edition on a Windows 2000 member server in an NT 4 domain. We will be migrating to Exchange 2003 in a Windows 2003 domain. Can anybody recommend a good archiving system that will be compatible with both versions of Exchange? I am currently looking at Legato EmailXtender Archiving Edition and IXOS-eCONtent. Any suggestions will be appreciated. Regards Mel
