For a few years, I have been syncing my Outlook contacts and calendar via a Microsoft Account with no problems. Am currently running Outlook 2013. When trying to access my contacts in Outlook 2013 from my desktop computer (Windows 8.1), i first see no contacts, then see the syncing starting and many contacts appearing but not all. My Windows Phone (7.5) also is experiencing syncing issues and shows an error 86000106. Futhermore, my tablet computer (Windows 8.1) and Outlook 2013 started the same problem today. So, I know this is a Microsoft server issue, not something on my devices. Am interested in knowing if others are having the same experience.
