Exchnage Server 2010 Users sending attachments but recipients are getting WINMAIL.DAT files?

Hi,
We have recently deployed Exchange 2010 within our organisation. All clients are using either Outlook 2007/10.

A number of clients, not all have reported that attachments sent to users outside our organisation are receiving windat.dat files?

I have checked that they are sending in HTML text format and the same seems to be happening.

Is this a server configuration issue.

Stumped.

Cheers

Yes, easiest resolution is to create a remote domain for each domain that you have issues with and dissable Exchange Rich-Text format on the Message format tab otf the remote demain.
Thats in EMC  Org config - Hub Transport - Remote domains.

Thanks

I added the domains affected and disabled the Rich-Text Format.

I also did the same for the default domain.
The outlook settings were set to HTML. For the users affected I also changed them to use Plain Text.

Looks like either way is valid fix as the users can now send attachments without them being converted into windat.dat
