Hello all! I would love some help on this issue. According to my boss he quit receiving email last night around 10:30PM. You can send outbound mails to something other than our domain and it works fine. You just can't get inbound mail.
I went into our Exchange Management Console to see if I could fix the issue and found some information out. I used the queue viewer tool and it looks like all of our inbound mail is there, it's just not being routed or transported to the proper mailboxes. I have restarted the server 3 times. Did a hard shut down once. Started and stopped all Exchange services. I just don't know what else to do to fix it.
Nothing has changed on our Exchange Server in months. We are using Exchange Server 2010. Any help any of you fine expert folk could provide would be so very appreciated. Please just let me know if you need any further help and thanks again.
