I created a profile using the Configurator app to add 2 E-Mail accounts with SMIME signing enabled. I added the certificates to the the profile as well and selected them in the E-Mail Accounts advanced settings. The certificates are Issued by Digicert. However even though the certificate shows up in the advanced settings and is selected my Mail app keeps telling me that:
Unable to Sign You can't send signed messages because a signing identity for the address "@.***" could not be found. Go to the Advanced settings for this account to choose a signing identity.
I tried:
- removing the profile and manually setup the accounts
- recreating the profile from scratch
- creating a seperate profile that only installs the certificates
SMIME signing is enabled and the required certificate is selected.
The same certificates work on my MAC and Windows devices. The file format is .p12.
