Unable to open, send, receive emails

Hello

 

we switched to Office 365 thru Godaddy and some of our emails are received as Winmail.dat files and they cant be opened.  the problem is that some web based emails, yahoo and aol are not liked my microsoft.  after 2 months of searching, i found the cure and checked it with the folks that had issues and they were able to open the attachments with no problems.

 

you need to make sure you log in from your main email address that the office365 is set to.

 

but here is the link for the cure, so far !!
