That would be a router change made around noon on Friday. I made a blanket change to the ICMP (ping) blocking for residence halls at that time on Friday, and this caught the ACD router as well, by virtue of the 35.11.x.x IP addresses. In addition to the ICMP blocking, port 135 was blocked. I have removed these blocks now for ACD, so Outlook should be functional again.
