We have just switched to Office 365 and are moving all of our users from our former mail server. We have our own domain.
I have set up three users with iPhones using exchange. The first two went no problem after entering user name and password they verified and sync'd. The third user successfully verified and sync'd. I sent him a test email and he received it. However, when he tried to reply or send an email to another address the iPhone can not find outgoing mail server.
Any ideas?
