This happens with old emails.
For example:
An email sent 7/6/2004, has a date created of 19/7/2005??
Any ideas what this could be?
I also note that if you put back an item into a folder from the deleted
items, it gets the date that it was created in the folder. (I dont
think this explains the above situation though).

The item could have been copied, imported, moved (move is a Delete and a Copy at least some of the time), etc.

If the CreationTime property is linked to the Windows File CreationTime,
then it could be simply that your file has the same name as an old file.
