This question has been posed in several forums here, and support specialists have asked for and received multiple email addresses to look into the problem, but with no resolution yet, at least not in my case.

It seems that a number of outlook.com accounts suddenly stopped syncing contacts, and many contacts, if not all, were lost from these accounts. It's not our phones, or any user error. It's something that happened to numerous accounts near the end of last month.

Moderators and support specialists have been involved, but feedback has been poor and I know of no repair that has actually been done.

Moderators, support specialists, what's going on?????
