for over 2 weeks now i cannot send/receive messages using windows live mail 2012.

the following error message is shown:

" Unable to send or receive messages for the ... account.

Server Error: 3204
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x8DE20003 "

i read several users with similar problems, and tried different ways to recover and fix the issue, but nothing worked.

at first it was the issue of being stuck in "updating calendar". then i found a way to solve this by changing the name of the calendar folder and messing with the windows time.

i uninstalled and reinstalled live essentials.

i removed and re-added my hotmail account in windows live mail.

other email accounts work fine in wlm.

no changes had been made to my internet setup.

i did clear cache and temporary internet files.

i am using skype, now signed in via my microsoft account (if that makes a difference - but i had been using this before the problem started).

i am using a blackberry smartphone that is set up to receive hotmail emails - thats relatively new, but also, happened before the problems started.

please help!

thank you!

UPDATE: i did a system restore (windows 7) and this seems to have solved the problem. but im afraid to click on calendar in wlm, because i dont want to be stuck in "updating calendar" again...but as far as emails, it works.
