Over the past few days e-mail messages disappear, can't find them, after I've ticked the box to close them they just disappear. Luckily I printed out an e-mail confirmation from easyJet before it went. This never used to happen, but I've changed ISP's and some of the settings may have been changed. Any ideas? Thanks
Try changing the destination that they are saved to.
To change the storage location for your Email Folder, go to Outlook Express, Tools, Options, then Maintenance. Click the Store Folder Button and you will be able to change it to another folder/location.
