Here is an interesting one. When moving messages around the following error pops up, not seen it before myself before so any ideas.

whats on the back end?.. exchange/pst etc?.. could be corruption of some description?

its exchange 2003, quiet a flakey server as well. Poor thing needs constant attention as several exchange background processes are broken and mailbox sizes are reported incorrectly in system manager and amongst other things the background cleanup process is very much broken. We were about to replace it with and Exchange 2010 box but local authority funding has been cut as we all know so the old girl has to keep plodding along.

It may have been caused when we deployed IE8 round the whole estate but I cannot be sure.

It's not a back end issue, its a client side issue. The error is a Javascript error in Outlook. Probably a result of IE8 and Outlook not playing well together, this is because Outlook uses IE to render HTML e-mails and has probably generated client side Javascript that uses a function considered by Microsoft as a security risk in IE8.

I would either roll back to an earlier version of IE or look to upgrade Outlook.

BTW there is a common misconception among many folks that upgrading the Sun Java runtime fixes Javascript errors. Java and Javascript are two completely different things and Javascript is solely handled by the browser.

What version of Outlook are you running, have you got the latest SPs / Updates installed?

Also do you have any Add ins for Outlook installed, in may be worth running Outlook in no-add in mode and seeing if the issue persists.
