MS Outlook 2010 receiving attachments at winmail.dat instead of as original format.

Hello Experts

I have a problem at present with a new installation of MS Outlook 2010.

I dont use MS Exchange and I am on an office network.

When forward an email that has a Word document attached the recipient receives it as a winmail.dat attachment, and not a Word document as I sent it.

I can send the same recipient the same attached Word document from GMail and they receive it perfectly, as the original Word document format.

Any assistance is greatly appreciated.

Thanks heaps

I assume you are using Word 2010. Go into Outlook Trust Settings for Attachment handling and loosen up those settings to see if that helps at all. Make sure when you send the email you are using HTML and not trying to use RTF.

If these do not work, try repairing Office (from Control Panel) and make sure you have installed SP1 for Office and have it fully patched.

Hello Thinkpads_User

The sending seems ok, in that when I view the same email using Webmail it displays the attached document as the original Word document.

Thanks

Another thing to try is to temporarily disable your antivirus and try sending again. That may be interfering.

If Gmail and Webmail work, it is unlikely to be your network. Also, I have Office 2010 and send documents all over the place - no issues at all.

So check your Trust settings (not part of Webmail or Gmail) and also the Office Repair (again, not part of Webmail or Gmail).

If you are using Office 2010, which account are you using POP for Gmail / hotmail / yahoo?

Winmail.dat is normally an issue with the recipient domain unable to understand the format of the email and hence they encode the email with an attachment which encapsulates your original email.

As mentioned above, using RTF / HTML / Rich-text are three formats, you could experiment with and check which one of these versions is of help to you.

Hi Exchange_Geek

Hey, I disabled the the Antivirus/AntiSpam and what to you know the attachment came through ok. Enable AV and attachment didnt come through properly.

I've contacted the AV vendor to see whats going on..

I'll let you know the outcome.

So then that is your problem.  I am using (along with my clients) Symantec Endpoint Protection. I am not asking you to change, but just to let you know all this works well in some instances.

What you might be able to do is to disable the option to check outgoing mail (if one) in your antivirus.

Problem went away once I temporarily disabled the antivirus software.

Turns out there was a setting to append an 'email scanned for viruses' message to incoming and outgoing messages.

Turn this appended message off and all works ok.
