Windows XP Oulook 2003 Outbox blocked by read receipt

[lindarollo]

I currently cannot use Microsoft Outlook with Virgin Media blueyonder account.

The Outlook 2003 outbox is blocked by read receipts which I can't delete. I used the info in www.outlook-tips.net/howto/delete_rr.htm

Where the instructions say Choose Delete, I have done this (using OutlookSpy). The message I get is

IMAPIFolder:eleteMessages() returned MAPI_W_PARTIAL_COMPLETION

and the read receipt is not deleted.

Has anyone got round this problem?

I use IOLO spyware, firewall and antivirus.

Thank you
Linda
