You may have a damaged identity especially if it is the default Main
Identity. File | Identity | Add New Identity. Create a new one and test it.
If all is well, you can import your messages and Address Book from the old
identity and delete it.

Hi

I am trying to create a sub-folder under my Inbox. This is something I
have
often done before. However when I click on "File" and "New Folder" etc
the
little hourglass appears for a couple of seconds and disappears, but no
new
folder is generated.

I had the problem some days ago. Then a few days later I tried it and it
worked!! Now it doesn't work again. Anybody any idea what's going on?

I am using Outlook Express 6 and a newly down-loaded version of IE7, if
that
has any relevance.
