I have a problem with one of my two Exchange accounts.
One is working OK, but the other refuses to work at all.
It just keeps saying "Internal server error". The only difference which exists between two servers is that the second have self-signed certificate. Could that be a problem and what could be done in that case?
Thanks in advance!

Update: It seems this is is the same problem with certificate already described many times in this thread. Are there any news about solution?
