I setup an Exchange 2013 server for the internal network only. The disk I had everything was getting full, so I moved the database and log directory to a different drive.
After that, accounts can send emails but not receive them. I know it sends because emails go to the Send Items folder and disappear without receiving an error.
Maybe this is completely unrelated to moving things to a different drive, but I am not sure.
Please advise.
EDIT: I see that the Logs are not being written to the new drive because of permission error. However, I did grant full access to the Administrator.
