How to force Outlook to allow MDB and EXE attachements
From ArticleWorld
By default, Outlook will refuse to attach EXE and MDB files to the messages you send. This is done as a security measure, since EXE and MDB files can have malicious content.
However, if you feel this is annoying and you are sure that you are not attaching anything dangerous, here is how to force Outlook to accept these.

Steps
- Close Outlook completely.
- Go to Start, Run, and start regedit.exe.
- Go to HKEY_CURRENT_USER\ Software\ Microsoft\ Office\ 10.0\ Outlook\ Security (or HKEY_CURRENT_USER\ Software\ Microsoft\ Office\ 10.0\ Outlook\ Security if you are using Office 2003)
- Go to Edit, New, String value. Name this new value Level1Remove.
- Double-click the value to edit it, and enter a semicolon-separated list of extensions you wish to be able to use. For example:
exe;mdb;doc
- Click OK and close the Registry Editor.
- Restart Outlook and try to see if it works.

Notes
Do note that this is a security risk.
Also, you should make sure not to do any mistakes while editing the registry. Keep a backup of the registry files at hand, just in case.
