Zimbra & BES, failed synchronization

[InesKa]

Hi all.

I'm a SysAdmin and I implemented Blackberry Enterprise Server 4.1.6 with Zimbra Collaboration Suite 6.0.1 Network Edition.
Everything was perfect for one year, but 3 days ago, after restarting Zimbra, all devices have failed to synchronize.
In BES everything seems fine.

I tried to resend service book, shutdown..etc, but the devices still don't receive mail. It does not work either.
I know this way works: wipping device, add user again to bes and activate mail in device, but I would not do it manually in 30 devices...

Any procedure to try from BES?

Are all the services running? Have a look in the log files for any errors (and search the forums for a resolution) and you should also check if your certificates are still valid (and regenerate them if necessary): Administration Console and CLI Certificate Tools - Zimbra :: Wiki

Thanks.

All services running ok and certificates are valid.

I see this in the log:

16-08-2011 15:11:10.371 [5052]: *699* ERROR: Zimbra::Rpc::Connection::SendRequest - failed on WinHttpSendRequest(...), Error Code: 12029(Unable to connect.)

Hi all.

First:
When I try to clean 2 Blackberrys and reconfigure corporate mail, I need try this too many times until it works, 8 attempts, 9....

And, mysteriously, after 4 days, two users have begun to synchronize mail on their devices, ( I have not done anything..., not clean devices, not reconfigure mail)

I don't understand...

Whe changed a proxy for the zimbra-proxy.
Maybe this affects the communication and RIM, Bes or Zimbra need some time to refresh any information..??

Any idea?

(Sorry for my english)
