MS Outlook 'Messaging Interface Error'
I am using MS Outlook 2002 and have started receiving the error message 'The Messaging Interface has returned an unknown error. If this persists, restart Outlook'.
This error occurs when I try to delete the messages that are sitting in the Sent box - they have been sent multiple times already but will not transfer to Sent.
I also have about 140 odd emails sitting out there waiting to be downloaded to the inbox which isn't happening.
I have tried running the detect and repair function but to no avail.
I have also deleted that backup .pst file as it was approaching 2gb.
I've restarted Outlook, restarted Window and still nothing is happening.
Is there another .pst file I need to delete other than the back up file that I manually run?
Thanks in advance.
