This appears to be associated with an ongoing worldwide Exchange Online incident tracked as EX1467029 and affecting many customers, and has started to be reported in the press (e.g. Cyber Security News).
- Update · UTC
Our provider Forward Email has confirmed the issue and is in communication with Microsoft to resolve it.
- Identified · UTC
We are aware that email forwarded from @cl.cam.ac.uk and @cst.cam.ac.uk addresses to Exchange Online (e.g. @cam.ac.uk addresses) is currently experiencing long delays.
We believe that this is due to Microsoft misidentifying our email forwarding platform as a source of spam. We have contacted the operator of that platform to see what they can do about this.
No email is being lost at present (except spam), but it may be delayed by several hours. Mail sent directly to @cam.ac.uk addresses seems to be unaffected.
