Go Daddy Hosted Exchange Winmail.dat

Hi all,

When utilizing Go Daddy Hosted Exchange through a reseller account, some recipients (mostly Yahoo/AOL) get attachments and only attachments as Winmail.dat.

Things to note:
This only occurs when sending attachments
The actual attachments never go through
Go Daddy is 100% hands off on the issue
Mail is being sent with HTML formatting (not plain text or RTF)

Many guides I've attempted to look up have said to either send all mail out as HTML or plain text.  HTML is what the mail is already being sent out as, and I am testing sending mail as plain text.

Any help is much appreciated on this issue, as this is effecting productivity.

Did you checked Outlook setting?

Yes, the Outlook settings are set to send as HTML.
I've requested that this question be deleted for the following reason:

Not enough information to confirm an answer.
This is still an issue and there has been no resolution found by Go Daddy or myself.
Do you type the email address of the receipent manually or there is a suggested contact for the said receipents?

Have a look of the link above. Winmail.dat problem is normally caused by the properties of a contact which has been set to sendby  email by RTF format instead of letting Outlook to decide the email format. Just change it to "Let Outlook decide..." and the problem will go away.
WINMAIL.DAT is sent when an email is using RichTextFormat (RTF) which can easily happen when the Outlook user is using Word for composing.
Here are several methods to fix that problem: https://support.microsoft.com/en-us/kb/278061
The lack of an attachment is probably due to another issue, altogether.

The winmail.dat is HTML formatting for Outlook, so when sent to non-Outlook clients you will get the formatting attached as winmail.dat.  The phone utility is awesome and does work, and for most clients RTF formatting is fine.  Also the other web based services like AOL, Gmail, Yahoo, are much better and handling this now than just a couple of months ago.  The calls coming in for this issue has completely halted.  Thank you all so very much for all of your help.
