Winmail.dat Problem

Hi there,

We have a user in our organization who, when she sends an email with an attachment, the recipient gets 'winmail.dat', instead of the attachment. I know the normal causes of this, which we've checked out already (rich text vs. html, etc.). The thing is, she can forward an email with an attachment to someone else in the organization, who can send it out fine to the recipient, who gets the correct attachment.

At the suggestion of another technician, we created a new account in Active Directory for this user, and she started using that instead, but the problem remained. We have an inhouse exchange server (2003), if that helps.

Thank you for any help you may be able to provide,
Peter J. Squicciarini

A more specific fix that worked for me before:

Reference from: http://email.about.com/od/outlooktips/qt/et121705.htm

Disabe Winmail.dat Stubbornly Going to Particular Recipients No Matter the Default
The standard settings for outgoing mail formats in Outlook can be overridden per email address. So, on a per case basis  when somebody complains about an inexplicable "Winmail.dat" attachment after you have made all the right settings changes , you may have to reset the format for individual addresses:

:: Step by Step Screenshot Walkthrough
Search for the desired contact in your Outlook Contacts.
Double-click the contact's email address.
Alternatively, click on the desired email address with the right mouse button and select Outlook Properties... from the menu.
Make sure either Let Outlook decide the best sending format or Send Plain Text only is selected under Internet format:.
Click OK.

vacnet,

I tried all steps in the MS article, as well as the specific fix for contacts. All the settings were already set that way, so I didn't change anything.

I'm assuming the affected User is sending email through Outlook. Can she access webmail? If so, try sending through webmail to see what happens.

The user affected is using Outlook 2007. And when she sends through webmail, the winmail.dat problem doesn't happen. All works fine in webmail.

Just wanted to confirm that you did change the Outlook Properties for sending via "Text Only" regarding that "specific" recipient in the Address Book.

Yes, those settings were already set. We didn't change anything.

This small suggestion may seem a little petty but it's worth a try. Have the user attach the file using the attachment button (paperclip icon), instead of dragging the attachment into the email.

I haven't tried it but there's a decoder designed specifically for attachments like winmail.dat.

Or try:

1. Export a .pst file from the effected account.
2. Create a new profile in the Mail tab in control panel.
3. Setup profile and import the .pst file you made.

as mentioned in:

I can have her try the 'attach button' option...
We really can't deal with a decoder or anything - we need to just resolve the issue so nobody gets these winmail.dat files. It definitely seems like a problem on her end, because someone else in the same domain was able to send...

Since we gave her a completely new account, do you really think the new profile in Outlook would make much difference? I can try it if you really think it will help, but otherwise it's a pain.

Thanks for your help so far,
Peter

Sounds good psquicciarini. Go ahead and try the solutions and let us know what you find. I know how much of a pain profiles can be sometimes; but this winmail.dat has definately became a bigger problem than expected. I think after many days and failed attempts, anything is worth trying at this point.

Well, she seems to have fixed it herself. I'm not sure as to what she did. Sorry for the inconvenience.  The points will go to vacnet for at least trying.

Thanks Peter. If you get a chance, I'd like to know how she fixed it. Seems this is a very common problem with minimal success in many attempted solutions.

Cheers,
