Many of the issues reported here are definately with the service, and even teh basic functions are either broken or intermittent. I was able to easlily populate my MM contacts with Outlook data, including Groups, yesterday, and they all came down into my iPhone just fine. But after several unsuccessul attempts at syncing up a second computer I basically had to manually consolidate and organize contacts spread over the two machines, and start from scratch. Now, I can't get MM to populate at all. The only support article says to log out then back in again, and from posts here, I've also tried different things. It would be nice to have some communication from Apple what the known issues are, and when certain features are down.
