Connection issue with Exchange Server 2010


I am using eM Client 6.0 and my Exchange Server version is 2010. When I do sync I am getting the following error:

8:50:22 AM … [Exchange Web Services] MailExceptions.ConnectionException: Couldn’t get server version.
8:50:22 AM at MailClient.Protocols.Exchange.ExchangeAccount.get_ExchangeService()
8:50:22 AM at MailClient.Protocols.Exchange.ExchangeGenericCommand.Execute(WorkerStatus status)
8:50:22 AM at MailClient.Commands.Command.Process(WorkerStatus status)

Thanks in advance!


Hi, we have implemented some exchange synchronization tweaks in this version… please update to it and let me know if it works.


Thanks for the reply.

I uninstalled my previous version of eM Client and installed new one from the URL… but still having the same issue. See the screenshot.



I will need your Exchange Web Services logs, go to tools - settings - advanced, check Exchange Web Services under your account, apply and restart eM Client.

Simulate steps that leads to your issue and after that send logs… to [email protected] together with this topic’s URL in subject.

then you can turn logging off.


I sent log to your email [email protected]

hi, could you try newest version? It was released yesterday… it might help you as we have implemented some fixed to Exchange synchronization issues,



Thanks for the update.

My eM Client license was expired. So I tried to get free license key from URL but nothing happens after button click.

this is meant for new license only, it will not work if you have used your email once before (one free license per one email), try to use this link…
