Hello All,
I have a very strange problem in my office. At the new years eve, there was a disconnection in our Internet from our ISP and everything came back online again after 1 hour. before this happened everything was working fine such as externally all the mobile devices were able to connect to exchange 2013 and event owa was working fine and laptop devices as well. All was good, but once the disconnect happened, i am only able to access my emails over 3 G connection but not over the ISP connection, what i mean from that is that if i try to connect to owa or my outlook from home DSL connection i cannot connect but with my 3g connection on my phone i can connect and everything works fine. i have re issued the certificates and installed them again, but still the same thing, after every hour or sometimes less the exchange 2013 sort of disconnects and starts working when i restart the CAS server where the traffic is routed to.
Has any one faced this issue, please help, i was thinking that something wrong with my firewall as i was not even able to connect to my ssl vpn so i thought that firewall is culprit, but i have replaced the firewall as well and still the same issue.
Please help, i am trying to troubleshoot this problem since last 10 days but with no luck.
Thank You.
