Synchronization error 0x800488EB

There are many users who are suddenly facing error 0x800488EB when trying to synchronize an HTTP account (i.e. one with an inbox at http://mail.live.com). It might be helpful for those trying to find out what's wrong to have some information about the accounts that are failing to synchronize. If you are experiencing this problem, please click Reply with quote under the post below this one and fill in the blanks in the Your data column. If you have more than one failing account, please fill in a separate form for each one.

Here are some tips for finding the data to enter:

1.   How to find out the version of Windows that you are using

2. & 3.   Which version?

5.   Visit http://mail.live.com and sign in with the failing account. The server cluster is given as the first part of the URL in the browser address bar: http://dub129.mail.live.com/Default.aspx

Type any additional comments in the white field below the blue box, then click Submit.

Thanks to everyone who filled in forms. This made it possible quickly to rule out a number of contributory factors. The MS engineers are working to find a solution which will be put in place as soon as possible. In the meantime, I'll post a couple of workarounds.

Thanks for this hopefully helpful grid for Microsoft to use.  Hopefully they *will* use it!  If I misunderstood any of the questions and answered them wrongly, let me know.  I'm not much of a techie person.
