Can multiple Unity servers reside in an AD domain and point to the same Exchange cluster? The reason I ask is because we are nearing our 512 CSS length limit and figure that if we can have 2 Unity CSS (1 for each server) then this may be a viable work-a-round for the limit. Any other suggestions regarding a work-a-round for the 512 character limit?
yes, you can have several unity servers in the same exchange cluster, even pointing to the same server. but if you have several exchange servers it's a good idea to have different partner servers.
the limitation of CSS is 1024, 512 in line CSS and 512 in device CSS.
if this helps, please rate
