I'm guessing these are the special sync folders that Outlook has to show issues between the online folders of your email provider and the offline copy that Outlook keeps on your computer. Generally, Outlook works with the online email but stores an offline version so that you still can see the emails if you don't have internet access.
I get these messages occasionally. I think the errors are related to internet connections being dropped while a sync is happening. I've never been able to prove there is an actual problem as I think Outlook is able to solve the issue the next time the connection returns.
If you have multiple computers or devices all doing this (I do), then it's possible it could be more of an issue.
Sorry, not a lot of help other than to say some amount of these messages seems to be normal.
