(Referred here from http://answers.microsoft.com/en-us/office/forum/office_2010-outlook/error-4202-when-synchronizing-outook-2010-with/dbd93cad-84ca-4cf4-b11f-11186c7696c3)

I get the following error when I try to synchronize Outlook 2010 with my live.com email account:

[from Sync Issues folder]

...

15:23:09 Synchronizing server changes in folder 'Junk E-mail'
15:23:09 Done

15:23:09 There is an error synchronizing your mail account. Please verify your account is configured correctly by first accessing your mail on the web.

15:23:09 Error: 4202.

My safe senders shows as the same in Outlook 2010 and on outlook.com, and my blocked senders list is empty. I've tried clearing the safe senders list both on outlook.com and in Outlook 2010, and they sync, but the error is still reported. Interestingly, I have two PCs running Outlook 2010 that synchronize with this email account, but only one of them sees this error. I've tried deleting my OST file and resynchronizing from scratch, but the error returns after a couple of syncs. I am running Microsoft® Outlook® Hotmail® Connector 32-bit ( 14.0.6123.5001 )

Is there something that needs to be done on the server to fix this problem? Or is there some additional state on the client that I can reset?
