Yesterday morning I realized I did not get any mails over night so something must be wrong with the sync of my Windows Live/Hotmail account. After checking my Windows Live account under settings –> Email+accounts I could see the message “account is not up-to-date”. By tapping on the Windows Live account I got the following error message.
Windows Live error Not updated We're having a problem synchronizing with m.hotmail.com Last tried [xx] seconds ago Error code: 8600108
After searching the web for some time I found the solution, the problem only appeared when I was syncing E-Mail. After unchecking the E-Mail check box the sync worked fine, except the mail sync of course. Now after it seems that this had to be a problem with a email. I deleted the latest messages on live.com and check the checkbox for E-Mail in my Windows Live account on my phone again the sync worked fine again.
From support.microsoft.com:
This error can indicate a back-end mail server issue, which may be caused when Windows Live tries to sync an email with a large or problematic Word document such as an attachment. There could also be a temporary service outage.
