we have some of exchange server (for example A, B, C, D)
we have only one BES server
all users in one of our exchange server (for example exchange server C ) cannot send and receive email

C is located in other town, phone provider said that they have no problem since
all users can do browsing to Internet and phone number not blocked
I did test using blackberry with Wifi but the email problem still exist

we did hard reset, rebooted exchange server ( c ), rebooted BES server
any troubleshooting suggestion will be appreciate
thank you

thank you

What versions of BES and Exchange are you using?

Does Exchange server C have the same versions of mapi32.dll and cdo.dll as the others?

[knottyrope]

What version are all the mail servers?
What version CDO.DLL on BES?

What is you ping time on C?

How many BES users on each exchange server
