meeting requests to external recipients accept/decline status not updating

We have a handful of external domains that, when we send meeting requests to recipients at these domains, we either do not receive any meeting accept message back or we do get the accept message but it is missing the message.ics embedded portion which seems to be required to update the meeting attendde's status.   We have confirmed that the recipients are receiving the meeting requests and accepting them.  Something seems to be blocking the accept responses and/or the message.ics portion of the email.  I do not believe the blocking is on our side since it is only three domains we have this issue with.   The recipient domains are also using Exchange.  I've searched for days, no luck.  Any insights?

are you using RBLs, SMSMSE, anything like that? Also, does it work fine for other domains?

Turns out this was caused by the winmail.dat embedded attachment being blocked by the external recipient's system(s).   Winmail.dat contains the data which Outlook will process to update the acceptance status in the meeting organizer's Outlook.
