MS Echange 2007: Cannot send attachments ActiveSync/ Не отправляются вложения c мобильных устройств (IOS Android)

Open up the Exchange Management Console

Server Configuration----> client Access ----> Exchange ActiveSync tab.

Double click Microsoft-Server-ActiveSync Properties. Go to Authentication tab...Make sure check on Basic authentication (mine was already set to this) and check "Ignore client certificates" (default is set to Accept).

After doing this, the attachments send ok.
