In German universities Microsoft's mail services had the reputation of randomly swallowing individual emails like a black hole - never to be found again.

I haven't heard about issues like these for a while, but it was also difficult to recognize them in the past. Unless people expected an email, they didn't report them as lost. Most mailops I talked to expected it to be a spamfilter issue: E-Mails that got too bad of a score for random reasons were just not delivered, not even into the spamfolder.
