I sent a small pic to the MAC user and it was received. I sent a message from MY domain (TTE) as a test to see if the problem was in my client's setup or the MAC users'.Sending to the same MAC user from my domain (also office 365 and outlook 2010).Setting up their mail in my Outlook (outlook 2010).I have been told the problem is on the other end (the mac user's end), but I have a hard time believing that ALL of the MAC users (hundreds) are the problem, especially when it sends and receives fine from OWA. After doing that, they can receive an attachment if they REPLY to the MAC user and then INSERT an attachment. "reply with changes" i put a ck mark in the box "add properties to attachments to enable replay with changes". In looking for some setting in Outlook that could be causing the problem, I went to File, Options, Trust Center, Trust Center Settings, Attachment Handling, and under If they use the Outlook Web Mail interface, they can send the attachments with no problem. They receive the email, but no attachment. When the email ANY of their clients that use a MAC, the MAC user does NOT receive the attachment. They use Outlook 2010 as their mail client.
