Good morning,
I have a sbs2011 server with exchange 2010. We recently, as of 12/1/2017, started to have issues with our server locking up during the backup process. Because the server goes unresponsive, I am forced to perform a hard shutdown of the server by holding down the power button. Once the server is brought back up, and we log in, noticed that the time is off. Have that issue resolved now but we are not able to send or receive emails from inside or outside of our domain. I can login to the outlook web app without issues. Internet is working as well. Any ideas?
