Thanks CF - both accounts are running the same.
Thanks Jordi- I've tried copying, after saving to My Documents, to my external drive but kept getting an Error message (which disappeared when I closed down Outlook!).
Have now managed to save to the external, and have imported the emails etc back to the original User. This of course means that I have duplicates of each email!
Still better that way than losing all of them, I suppose,
Thanks for your help........
