TNEFEnabled Question - Sending invites or sending attachments

    Question

  • We created several room mailboxes for our conference rooms in Exchange.  When our end users send invites to these conference room to internal attendees, we do not have any issues.   When they send invites to these rooms to external attendees, this email gets caught up in the exchange submission queue.   After doing a lot of research, I was pointed to: Set-RemoteDomain Default -TNEFEnabled $true.  This worked great, those invites aren't getting caught up in the submission queue.

    Now, I have other end users, who email attachments to external people, who say that they don't get that attachment but a winmail.dat attachment. I tried it myself, and yes but only to certain organizations like AOL and AT&T (Yahoo) - to just name a couple.  however if I send the attachment to live.com or gmail.com the attachment comes through fine.   Also when I:  Set-RemoteDomain Default -TNEFEnabled $nul - all organizations I tested came through just fine.  However, the invites get caught in the submission queue.  

    Is there a solution to this?

    Thank you,

    Scott.

  • Niko -

    I'm still getting these messages caught in the submission queue.  Is it normal for a business of over 150 users or for that matter any business to have their employees forward calendar meetings as an .ics to the external attendees?

    Are there alternatives?

    Scott
