| | BES with multiple exchange servers in different physical locations
Please Login to Remove!
we have an environemnt of 2 exchange servers and 1 BES. all located under the one domain.
exchmel is located in Melbourne and hosts melbourne users mailboxes and exchsyd is located in Sydney and hosts sydney users mailboxes, and BES is also located in Melbourne.
this has been implemented for some time and is all working fine.
recently we had an outage whereby the connection between the sydney office and hence exchsyd was cut off from the melbourne office.
during this outage, sydney blackberry users were unable to send and receive emails to their blackberry.
i presumed that if one exchange server was down then the other would effectively take up the slack. hence all blackberries regardless of which exchange server the user's mailbox is tied to, would still be able to send and receive emails. however as mentioned this was not the case.
is there somthing i can check or need to do? or is this simple a limitation of the architecture
