After we migrate a user to Exchange 2013 SP1 from Exchange 2010 SP3, a users signed email message can't be viewed from their mobile device.
The users receive the following message:
"This encrypted message can't be displayed because this version of Exchange Server doesn't support encrypted S/MIME messages on mobile phones. To view this message, you need to open it on a computer using Outlook."
Is there some additional commands I need to run to allow this through ActiveSync?
I've run this command for OWA S/MIME already:
Set-SmimeConfig -OWAAllowUserChoiceOfSigningCertificate $true -OWACRLRetrievalTimeout 10000 -OWAEncryptionAlgorithms 6602:128
