So as not to have a new post about this every other day:

Yes, the Microsoft weather has not been updating for about the past month now.

Yes, this is for both FSX and FS 2004.

There have been brief outages in the past and weather has always returned. At this time there has been no official word from anyone about the future of the MS weather.

In the meantime there are plenty of 3rd party weather programs, either freeware or payware, for our use. A search of the forum will provide plenty of information about said utilities.
