I have used outlook.com with Outlook 2013 for many years. I have many subfolders and many emails in each folder. I was recently upgraded to the new version of Outlook.com and have been having synchronization problems. I deleted my previous OST file, and the account began to resynchronize, but some some subfolders are not showing all emails. Other folders (inbox for example) are showing unread messages on Outlook.com despite showing no unread messages in Outlook 2013.
I have set "Mail to keep offline" at "All".
Thank you,
David
