I am helping a small company that currently have an external hosted MAPI solution in Outlook 2010-2013. It runs on 6-7 computers and for all users their outlook takes between 15-60 seconds to start, freeze when they search and so forth. They share a small 4mbit internet connection and a desperate for a solution. On each computer there is some kind of MAPI client running, I don't know what it does.
The company running the MAPI solution have told us that is running as it should and that it can not be improved.
Therefore we are in need of some kind of solution. I haven't used MAPI solutions before, so I have no experience with it, but we tried to move the archive data away from the MAPI and host it on an GMAIL, just to be able to compare speed, and also to see if the MAPI would perform better if we removed 50% of all data on it. Sadly there were no improvement for the MAPI solution, but the gmail works as fast as always.
I read that using MAPI should be fast and work great with outlook, but it doesn't in this case.
Would it therefore be a good idea to switch from MAPI to GMail (or another IMAP service) or am I missing something the could be tweaked in outlook to make the MAPI-email run fast.
Any ideas are much appreciated :)
