Outlook duplication.
Signed in to Outlook yesterday - and was told that I had 1560, 250 Mb, of e-mails to download, took 4 hours and duplicated every e-mail that I have saved in various folders over the past couple of years and started a new folder of Unread e-mails for the lot of them.
Yes, I could have stopped it but was fearful that it would started up again next time, so just sat and watched.
If I delete anything from this new folder, it also deletes it from the original folder that it has harvested it from.
WTF ?
