our landlord phone system sends voice mails to email via a wav file attachment. we were able to listen to the wav file in all places, i.e. Outlook, OWA, and iPhone/iPad before moving email from SBS 2008 (exchange 2007) to Office 365.
other change at about same time iOS 7 upgrade.
the current chain goes like this Phone system send to the landlord Exchange 2010 server > the exchange 2010 sends to our Office 365 (exchange 2013) > emails to devices.
Now, we can listen to the wav file on Outlook and OWA but cannot listen on the iPhone/iPad. it shows as a MIME attachment.
the strange thing is that if your forward the email from Outlook to yourself the wav file will play on the iPhone/iPad.
any searches regarding the MIME attachment generally says that you do not have an app for the file type but of course there is one.
I am thinking it lies with Exchange or office 365 but have been through both the exchange 2010 and O365 and can't find anything actionable.
any help would be greatly appreciated.
