When attempting to send Exchange email on an enrolled iOS 7 device, the Mail client does not send the note. Devices on iOS 6 appear to send email successfully. Both devices can receive and read email.
No error is displayed.
A generic EAS configuration profile sends an email value in the format of "domain\firstname.lastname@example.org" to the iOS device. In iOS 6, the Mail client synchronizes with the Exchange server and changes this email address into one of the valid SMTP addresses for that mailbox. In iOS 7, the device does not change this address and is unable to send email.
As one possible workaround, organizations that use their email address as the enrollment URL during SMM agent enrollment can place the email variable into the EAS profile. This will explicitly send the users enrollment email to the device as their Exchange account email address. By sending this address, the iOS7 device should have a valid SMTP sender address and be able to send mail.
Please see www.symantec.com/docs/HOWTO77270 for details about using the email address as the enrollment URL in the SMM agent.
If users have enrolled using their email address, put the email token into the "Email Address" field in the EAS configuration profile. See article www.symantec.com/docs/HOWTO79497
In organizations that do not use the DNS TXT record and email address for enrollment, the "user" token may provide another workaround. If the enrollment username matches the username in the user's email address, the "user" token could be placed in the Email field. You would then append the proper email domain to the token in that field. The result Email value would be your variable username@domain you specified.
This issue is being fixed as part of the SMM 7.2 SP3 release.
