I contacted Samsung and used their remote service to access the phone and they couldn't find a problem and thought it might be a carrier issue.
I can access the internet and receive emails using data I just cannot send emails unless connected to wifi which can be an issue if I'm out of the office and need to reply on the go. Help!!
That's odd. Normally that problem is the other way around. Commonly people can send email on data but not over wifi. Usually an issue if using an @telus.net email address with old settings on a non Telus wifi connection.
Are you trying to use a work email address or an @telus.net address? What error message do you get?
Has this problem been present since you got the current phone or has email previously worked over wifi on it? You've checked the SMTP (outgoing server) settings as well? Some times it could be something as minor as one little setting that's off.
