hi

is there any point in setting up a CAG when you only have 1 CAS server per AD site.

i am not using loadbalancing and only have 1 CAG, just wondering whether it makes sense to use CAGs' or not? the only advantage i can think of are

a) add more CAS servers in future
b) replace CAS server with new CAS server and you don't have to change outlook profiles for mapi connections?

would you agree or just leave the outlook mapi connections to connect to the FQDN of the CAS server instead of a CAG ip address?

i do have a 2nd AD site with a DR setup (CAS/HUB and mailbox server) with their own namespace so i would have to setup a separate CAG there as well if i would do the same in the production site

many thanks

By CAG I assume you mean CAS Array??? If you only have one CAS per site then I really do not see why you need to create it. Might as well wait until you setup a new CAS server just to avoid any possible issues.

yes i meant CAS array sorry  . I found an technet article that suggest even if you only have 1 cas server to setup a cas array anyway, sadly i can now no longer found the article having searched for the last 30 minutes. but i did read it, it makes it easer to later on add a new cas server and or replace your cas server.

I would setup a CAS array even if you only have one CAS. Simply because all it requires in a DNS alias to start with. If you want to add in another CAS server and load balance you don't have to worry about outlook profile troubles.

I know the technet articles you speak of, but also can't remember where they are :)
