I can report my personal experience and others I know: Università Politecnica delle Marche (located in Ancona) used to adopt a self-hosted Squirrelmail soultion, now It's migrating to Microsoft Hotmail; Università degli studi di Ferrara is using Gmail; Università degli studi di Parma is using Gmail; Università degli studi di Bologna is using Microsoft Hotmail.
Bern University in Switzerland also unfortunately migrated from a well-functioning Unix mail system to Microsoft Exchange a few years ago. I tried very hard (as an employee at the time) to find out how and why this happened, but nobody would tell me and nobody I knew cared one way or the other. Of course it suited users of Microsoft Outlook and also many more people started using the Outlook Calender in a Browser.
