I installed CCleaner yesterday and ran the Cleaner and Registry fix. Subsequently, when I go to outlook, I am unable to see anything in my Sent mail folder. All other folders are ok. Mail is still being sent, but shows in Outbox despite it being sent. I use AOL through Microsoft Outlook and have not had any problems before. Not sure what happened. Can anybody help? Thanks.

Did you make a backup of the reg entries you deleted? I'm guessing you let it delete something along the lines of
HKEY_CLASSES_ROOT\MailFileAtt
HKEY_CLASSES_ROOT\mapifvbx.object
HKEY_CLASSES_ROOT\mapifvbx.object.1


or something else that is needed.

If you accepted the prompt to make a backup of the registry entries you were going to delete using the registry cleaner, now would be a good time to restore them.

They are kept by default in ''my documents'', right-click and choose merge.
