I have the same problem. Started a few weeks ago. As you say, its fixable if
you delete the Hotmail account and recreate it. A while later it does it
again.

I also cant find a clue from any forum .

Hey Microsoft - can u fix it for us please??

I deleted my hotmail account from outlook and added new again...it worked.
HOWEVER, a few days later I had the same problem. There is apparently a bug
but I don't know how to address. I searched Microsofts web site for the
error code and they don't even show any official results.

yes. i'm having the same problem as well. Now I can't check my hotmail inbox
anymore from outlook 2007. I think i should just delete the acount and then
add it back.

Hi All,

About 3 weeks ago, I started getting this error message (Folder:Inbox
Synchronizing headers. 'reported error (0x80040604) : 'A folder by this name
already exists.') in Outlook 2007 when trying to sync up a couple of hotmail
accounts I have. Figuring it may have just been a random error message, I
restarted both Outlook and my machine, but to no avail, the error did not go
away. Anyone seen this message before and know how to resolve it?

Thanks,
Drew
