Hello,

When I try to send an email with my Outlook.com email account via Microsoft Office Outlook 2010 the following error message appears:

"Task 'Outlook.com' reported error (0x80004005) : 'There is an error synchronizing your mail account. Please verify your account is configured correctly by first accessing your mail on the web.  Error: 4202. '"

From reading other threads I have discovered that this issue is caused by invalid addresses/domains in the Safe and Blocked Senders list on the Outlook.com web client. My Blocked Senders list was blank, but I had several hundred addresses/domains in the Safe Senders list. I tried deleting the whole list, and everything on the list deleted fine except for three invalid domains that contain non alpha-numeric characters or don't have an "@" symbol. Whenever I try to delete them, they are still there upon page refresh.

Could you please manually remove the invalid domains for me? If a Microsoft representative can PM me I can give my affected email address.
