After migrating a server to hyper v exchange database was corrupt and fixed with esutil. Email started flowing but there were issues with connecting mobile devices. One user had an issue where they would receive spam email to their junk folder, and can send email, but email all other email is not delivered to their inbox. Several users users stopped receiving email at 4pm yesterday. Application logs stop at 8pm so i cannot see events that happened at 4pm. There are excdo 8199 errors in the application logs today.
I have turned town the SCL but that just allows more spam through.
