I have my work outlook account synced on my Samsung. For the first month, sending and receiving emails from my phone worked fine. Currently, I am able to receive emails but when I try to send them I get the error "Unable to sign or encrypt message. Certificate not installed" and I can no longer send on my account.

Does anyone know how I can fix this?

There's a known issue on Samsung devices. Please see here: http://webcazine.com/7630/how-to-solve-unable-to-sign-or-encrypt-message-certificate-not-installed-error-on-galaxy-s4/

It'd be nice if you could detail what, exactly, the "known issue" is. If that link stops working there's no information here. –  Al E. Nov 15 '13 at 18:37
