I am having the same problems as someone on a previous thread however none of the solutions seemed to have worked, I can’t delete items from the inbox and it keeps resending emails in the outbox without deleting them?
I have attached the related thread here - http://www.experts-exchange.com/Applications/MS_Office/Outlook/Q_20942599.html
• When I try to delete a mail message I get the error message: “The messaging interface has returned an unknown error. If the problem persists, restart Outlook”
• After the down loading has stopped I get the following error messages for all the mail boxes where there are messages waiting to be downloaded: Task ‘EMAIL ADDRESS’ - Sending and Receiving' reported error (0x8004060C) : 'Unknown Error 0x8004060C'
• A message which is sitting in my outbox (addressed to myself as a test) is uploaded every time and use the send and receive function. However the message is not moved over to the sent folder after the upload and is therefore uploaded again the next time the “send and receive” function is performed. Messages are sent to the sender but appear stuck in the outbox….
• When I try to move a mail message from one folder to another I get the error message: “Cant’ move the items”
Thanks so much, Natalie
