My project has ExchangeClient 2003 implemented and configured. This was working fine until yesterday noon exactly at which time connection errors were issued. According to the sysadmin of the exchange server yesterday a new SSL certificate was issued. Could this be why the mail exchange between my project and the exchange server? If so, how to implement the new configuration? I don't remember anything about assigning SSL certificates to the ExchangeClient module.
According to the documentation
The resources folder contains a privkeystore file which is where the library stores certificates given out by the Exchange servers it connects to. You should also include the licence for the library as mentioned in the previous section.
You should add the new key in that file.
Maybe the module creates this file locally when you make a connection to the exchange server. In that case you can copy the file.
