The Messaging Interface Has Returned An Unkown Error

[PTS]

Hi,

I am having issues with one user who manages multiple Calendars and is
always getting the following error:

'the messaging interface has returned an unkown error'

This happens when she tries to view someones shared calendar. Closing and
re-opening Outlook solves the issue but it keeps coming back. Please can
someone suggest something to try or at least an explanation as to why this
keeps happening?

Enviroment:

Office 2003 Pro
Outlook 2007
Exchange 2007

If you require further information please get back to me.

Many Thanks

PTS
