Opening Outlook 2003 Forms In OFT Files

Issue: Revert back to old behavior to allow .oft files to open.

Quick: Make changes to the registry

In the old days you could open outlook forms as .oft files from Outlook without installing them. Due to security issues Microsoft changed the behavior so that you now have to install the form before you can open it. There are times that it may be helpful to revert back to the old behavior. For one thing it can save a lot of mouse clicks if you work with oft files a lot.

Here is a link on how to revert Outlook 2003 to old behavior.

Not recommended: Re-enable the ability to create properties
Three registry keys can be deployed to client computers to disable the blocking of custom properties and revert Outlook to its previous behavior. These registry keys are supported by group policies. The following registry keys can revert Outlook 2003 to its previous behavior:

Note The following registry keys do not revert Outlook 2007 to its previous behavior.
AllowTNEFtoCreateProps (HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Options\Mail] "AllowTNEFtoCreateProps"=dword:00000000): If the value is 0, TNEF/MIME cannot create new non-Outlook custom properties. This value is the default value. If the value is 1, TNEF/MIME can create new non-Outlook custom properties.
AllowMSGFilestoCreateProps: If the value is 0, .msg files and .oft files cannot create new non-Outlook custom properties. This value is the default value. If the value is 1, .msg files and .oft files can create new non-Outlook custom properties.
DisallowTNEFPreservation: To ease migration to this new behavior, Outlook preserves the original TNEF when custom properties are not created. The original TNEF is saved in a binary stream on the item that is saved. Outlook uses the following property tag to save the stream:
The HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Options\Mail] "DisallowTNEFPreservation "=dword:00000000 registry setting controls whether Outlook creates the PR_TNEF_UNPROCESSED_PROPS property.

Note The PR_TNEF_UNPROCESSED_PROPS property is removed from a message when you embed a message into another message as an attachment. The PR_TNEF_UNPROCESSED_PROPS property is also removed when you forward a message or reply to a message.

Copy this text (between dashed lines) to a file called OFT.reg
Windows Registry Editor Version 5.00

Save it and then double click on it to upload the registry changes.

On my computer exist numerous different files. But most of them are outlook files. And one day something happened with theirs. As has turned out all of them had been crashed after virus attack. For luck I found an exit in this condition - recover ost files. It helped me and I advised it for my friends. I have received some gifts from my friends for this utility.
