If I can run multiple mail servers while seriously lacking in A levels and no desire for a degree (my partner has one in chemistry and is now a well paid bean counter, i have lots of random technical qualifications over 25 years and we are on a similar wage / just under £100k between us) is it so hard to expect a university to do it...
Read the small print, the student run servers amongst other things include 'lifelong email forwarding after you leave the university' that's nice. I expect the university will still be there long after MS has disappeared. The students will probably invent the next best thing and still be pushed aside because corporate greed.
Anyway since when is it OK for all our email to be read by our American overlords? Huawei are not allowed to do it.
