Weird Exchange 2013 mobile send issue

[Django x2]

I'm guessing not much people have had chance to play with Exchange 2013, or even installed it into production yet, so this request might fall on deaf ears.

Basically, greenfield Exchange 2013 domain. OWA works fine, Outlook works fine, all mobile device accounts can be created but these are the issues:

iPhone:
Account creates fine
Emails received but only headers
No send (errors)

iPad
Same as above

Android
Account creates fine
Emails received (fully)
No send (errors)

Not sure what to check now. I've tried the mobile logging feature but that returns very little.

Ah, this is the thing, currently we are only running self signed. We did the same with Ex2010 and that used to work fine however. Perhaps something has changed regarding the use of certs in 2013?

I'm thinking it's probably a cert issue. That and I just found out there's no autodiscover.domain.com in the external DNS which I've just added. Who would you recommend, GoDaddy? Do I then just do a new certificate in exchange, copy the key, download and complete the request?

Thanks for your help so far

no just the one server with all roles. As I say, all other forms are working fine, OWA (internal / external), internal Outlook, etc

Yeah, I knew about the local hostnames. That's going to screw up some very large companies I know.

Got the issue resolved as this:
Company owns to external domains (one of which is also their internal domain to tie in with the changes due in 2015). However, their main external domain for mail is not that one.

So, they have domain1.com and domain2.com (and domain2.com is also their internal domain). I'd added domain1.com as an accepted domain and somehow had set it to be the default domain. I reverted the default domain back to domain2.com and mail from the mobile devices worked again. I also set up a 5 domain SAN too so that's all good for OWA, RPCoHTTPS, etc.

Thanks guys
