When I reply to an email from the email address of an contact entry on the Global Address List, Outlook 2002 aborts with a "We're sorry...". The details show Outlook.exe ver 10.0.6863.0, module mso.dll ver 10.0.6858.0, offset 0000399b. Exception code is 0x00000ca4.
I can successfully send to the same contact by either typing in the email address or by clicking on the "to" button and selecting the contact from the Global Address List. There is no problem replying to others not listed as a contact in the Global Address List. This problem does not occur when tested with an Outlook 2003 client.
Both clients are running on WinXP Pro computers with hotfixes up to date. The mail is handled by Exchange 2007 on SBS 2008, recently upgraded from Exchange 2000.
I have tried deleting the contact and the reply then works. If I add the contact back, reply starts to fail again. I need the contact because I am using it for automatic forwarding on one account.
Any ideas on how to fix this?
