"Outlook blocked access to the following unsafe attachments..."  Can I retrieve this file?

I received an email with an Access MDB file attachment.  The attachment is unaccessible and the email contains the following message:

"Outlook blocked access to the following unsafe attachments: Christmas2009.mdb."

I'm reasonably confident that Christmas2009.mdb contains no threats (it's from my wife). Can I retrieve the file?

Was it blocked by Outlook or by an Exchange server? If it's exchange then there's nothing you can do about about it. MDB is an dataqbase format, were you expecting a db file?

You can try suggesting to your wife that she zip the file up before sending it to you.

No Exchange server.  Just a plain ol POP3 connection.  Is it retrievable?

Here is how you get your file.

1. Close Outlook.
2. Open the Registry Editor.
3. If you using Office XP/2002, expand the branches to HKEY_CURRENT_USER Software Microsoft Office 10.0 Outlook Security
4. If you using Office 2003, expand the branches to HKEY_CURRENT_USER Software Microsoft Office 11.0 Outlook Security

5. Create a new string value by selecting New and then String Value from the Edit menu.
6. Name the new value Level1Remove.
7. Double-click the new Level1Remove to edit it, and enter the filename extensions you'd like to stop Outlook from blocking. Extensions should be typed in lower case, without the dots (.), and separated by semicolons . For example, type
to allow .exe, .mdb, and .vbs attachments, respectfully.
9. Click Ok and then close the Registry Editor when you're done.
The next time you restart Outlook, you'll now be able to open previously-blocked attachments. (If an attachment is still blocked, you likely got the filename extension wrong.)

Make sure that you do this TEMPORARILY!

It worked perfectly!  (And it's now turned off.)
