I'm rearchitecting my Exchange 2010 installation and trying to do things geographically. We use SAN Certs here that only allow 15 names. I have 3 sites and some of the names overlap. Does this cause any issues? For OWA, Outlook Anywhere and ActiveSync everyone will use the same URL. For the CAS Arrays they will be different. thanks as usual Phil --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
