EWS - timout while processing EWS request

Question

Hello,
I search in mailbox by criterium and getting an itemlist with the IDs.
Then I am looping thru this list and make an ews request by GetMessageInfo(Id, EwsItemFields.Info) to get additional Metadata from the message, or doing some other things like export, delete

On tests with many messages (e.g. >50) I often get an timeout while calling GetMessageInfo(Id, EwsItemFields.Info).
The timout is 2 minutes

ErrorMessage:

Rebex.Net.EwsException: Error while executing request. ---> Rebex.Net.EwsException: Error while executing request. ---> System.Net.WebException: Error while processing request. ---> Rebex.Net.HttpException: Error while processing request. ---> Rebex.Net.HttpException: Response reading timeout.

Hello,

I just sent you an email with a link to newest beta build of our components. It contains some improvements in HTTP core for EWS. Please give it a try and let us know if it helps. If you encounter the issue again, please, create a VERBOSE log (you can turn it on after you connect and login, just before the get-list / get-message-info code) and send it back to us to our support email. We'll see if the info from the log can help to understand what is going on.

Hello, can you please create a log as described in my answer and send it back to us to our support email? Also, can you share some more info what are you trying to do? What kind of CF/windows mobile device you have?
I can see that you actually communicate with some web service that is not an EWS service.

Thank you for the log. This is the reason you are unable to communicate with the web service as found in your log:

GenerateContactless Error InEx2:Unable to resolve hostname.
GenerateContactless Error InEx3:No such host is known

Please make sure your network connection works properly. You can check your URL in IE browser within your device. Also make sure that the URL is not misspelled in your application.
