Open the Options dialog by clicking the button in the lower right corner of the ZipOut group.
Use the button to the right of the Separate/Combine toggle to launch the ZipOut Options dialog.
ZipOut allows you to set certain options such as password and comment on a message-by-message basis. The options are reset to their default (off) state once the message is sent or saved.
Outlook 2003 only : ZipOut options can be set for the active Outlook item and that item only. If you open another item and attempt to set options on that item while the original item is still active, you will see an alert message informing you that you can only set options on the original item.
Use Password Check this box to enter a password for the .zip or self-extracting file. The .zip or self-extracting file will be encrypted according to the Zip 2.0 encryption standard. You should be aware that the Zip 2.0 encryption standard is not as secure as the DES and RSA public key formats used by programs like PGP. The Zip 2.0 encryption format is not currently subject to U.S. Government restrictions on encryption technology, and can be broken by individuals with advanced cryptographic tools.
Warning The recipient of your message will need to enter this password in order to view or extract the items in the .zip or self-extracting file. Make sure that you remember the password!
Add Comments Use this option to enter comments for the .zip or self-extracting file. The comments can be viewed when the .zip file is opened using Windows XP or a Zip utility such as WinZip. The ZipOut Viewer does not display comments.
Combine Attachments Filename Enter the filename for combined attachments on the message. Do not add an extension. For example, if you enter My Attachments in the Combine Attachments Filename edit box, the recipient of your message will receive a message with all attachments combined into a file named My Attachments.zip. The Combine Attachments Filename is not used if you have chosen to Separate attachments.
