outlook 2010 winmail.dat

Hi

I have a customer whose program sends emails with PDF attachments via Outlook 2010 (32bit) on a windows 7 64bit notebook - he uses an external (cloud) Exchange server

Unfortunately his clients receive the attachment as WINMAIL.DAT that can't be read
I tried renaming the extension to PDF but that didn't help

I also tried setting Outlook's default format to "text only" or "HTML" but the situation remains the same.

Any tips, ideas ?

thanks
yann

The problem is to do with something called TNEF and how Exchange / non-Exchange systems interact.

You can fix this by configuring Exchange to disable TNEF when sending emails for specific domain names by running the following Exchange Management Shell commands per domain:

New-RemoteDomain -Name RemoteDomainName -DomainName remotedomainname.com
Set-RemoteDomain RemoteDomainName -TNEFEnabled $false

Thanks Alan, but the client doesn't actually have access to the Exchange server settings

Well - if they don't have access to the server to make changes, or they can't ask the hosting company to make the changes, then there isn't anything they can do other than point the recipients to an App that will enable to unwrap the winmail.dat attachment and extract the attachment from the email.

The alternative, is switch to something like Office 365 where they do have access to be able to disable TNEF for specific domains.  It may even be cheaper than they are currently paying!
