Unable to Delete Outlook 2003 EMails in Inbox when Sorted by Sender - Vista Home Prem

[M. David Petrella]

Hi;

When trying to delete emails in the inbox, I receive the following message:

The messaging interface has returned an unknown error. If the problem persists, restart Outlook.

This occurs when I try to delete more than one email, after I've sorted them by sender.

I have ...

1) re-started Outlook (as directed by the msg)

2) run Microsoft Update (to see if I'm up to date)

3) run "Detect and Repair" (to see if I have bad files)

So ...

I'm just wondering if anyone else has seen a similar situation; and / or if anyone knows where I might look for a resolution to this ..?

TIA!

p.s.

Microsoft Update installed SP1 for me; but this problem occurred before SP1, and now still occurs after SP1.





Grrrr!!! Just lost a reallly long edit ....



So here goes a very brief edit .... sorry ....

1) I can delete msgs as long as they're not older than 09/2007

2) Can't move old msgs to a Folder (just get a small pop-up w/ an "X")

3) RULES fail for older emails


Is this related to "[u]on this machine only[/]" restriction??
