We are currently experiencing problems receiving e-mail. All incoming traffic for today seems to hang Outlook up. In the application log I am receiving errors 145 & 150 every ten seconds. I tried rebooting the system but the problem still exist. I visited event ID to research the errors, 150 is unknown and 145 is a backup conflict. We do not have any backups running. At this point I have run out of ideas. Does anyone have any new ideas out there?
