I have an Exchange 2003 Server running in clusters. I have many stores on the exchange server. I recently had some users that were unable to connect and found an error relating to MAPI limitations met at 32 connections. I failed over the cluster to clear out the connections and that fixed the issue for now. I was told by Microsoft that they were certain this is why people were being denied access.
My question is what is the recommended solution to keep this from reoccurring. We have users with mobile devices, BBs, and attaching to multiple shared calendars.
Is the limit per store or per server? If I set a MAPI limit of 32 does that only effect the store or the server as a whole?
We have probably hundreds of users so we are not the largest environment.
