I have recently had a problem with my Hotmail account and calendar within Windows Live Mail 2012.
A few days ago my Hotmail account stopped downloading messages with an error message (which I no longer have a record of). I have since removed the account from Live Mail. If I add the account again, I get the message "Windows Live Mail is synchronising this account. Check again in a few minutes to read your messages" - this message never disappears, and my emails do not download. My emails are fine if I get them direct from the live.com website.
More importantly, about the same time my calendar appears to have a problem. It keeps updating the calendar continuously - this then stops it from rechecking my other emails. If I close Windows Live Mail down and restart it, it'll check emails, then the calendar without a problem, but then after a short while it'll say 'updating calendar' / 'your calendar has been updated' all the time.
I have tried repairing the installation. I have also tried uninstalling and reinstalling it - same problem.
Does anyone have any ideas? I'm not too bothered about the hotmail emails, but the calendar is quite annoying!
