We are running BES 4 with SP3 HF3 connecting to multiple exchange servers loacted in Australia. One server is located in UK..
Having issues with Wireless activation and delayed delivery for UK users, Australia is mostly OK.
I have been told the issue is probably latency, and logs seem to indicate that we are losing MAPI requests to UK users
I've seen alot of contradictory info on latency in the forums and RIM site.
What i have been unable to find is any definitive information on WAN requirements, e.g.
How do I measure the latency between a BES and Exchange Server.
What is the RIM recommendation/ Requirements for Links
I'm not going to be able to improve the WAN link unless I can show definitively (and testable) that the current link is the issue
