Outlook 2003 Error Msg (0x8004010F)

[Apota]

Sometimes when send emails on my Hotmail account with Outlook Connector I get
a pop up window with the following error message:

Outlook Send/Receive Progress
Then under the error tab,
! Task '(e-mail address removed) - Receiving' reported error (0x8004010F) : 'The
operation failed. An object could not be found.'

Does someone know why I'm getting these error messages and what I can do to
correct it? Thank you for your help and time.
