I'm working with a big Unity Connection deployment. It will exceed 10,000 users by year end and will likely hit 20,000+ users in about 18 months. I have two mailbox stores currently and I know I will need at least two more in the future.
My concern is which disk partition the mail stores reside in. My expectation is they reside in the common partition, in which case I have plenty of space. If the exist in the active partition, I only have space for one more mail store. I've scoured the Unity Connection SRND and Sys Admin guide but have found no answer to this question.
