The Blocked Senders registry key is damaged.

1.. Close OE and then In Regedit, navigate to this key:

|--HKEY_CURRENT_USER
|-----Identities
|--------{GUID}
|-----------Software
|--------------Microsoft
|-----------------Outlook Express
|--------------------5.0

where GUID is the Global Unique IDentifier for your Identity.

2.. Under that key, you will find the following sub-keys, among
others:

|-----------------------Block Senders
|-----------------------Rules
|-----------------------Signatures

Select the Block Senders Key and delete it. Blocked Senders will be empty,
but you can rebuild it now.

I recently installed then uninstalled IE7. Now I find that my Blocked
Senders list in OE6 has been de-populated and, if I add to it, the sender
will appear in the list as long as OE remains open. However, if I exit OE
and then return later, the entry has disappeared. Does anyone know how to
resolve this, please?
