For the past 2 weeks I suddenly can not send or forward emails from any of my accounts on my phone. I can receive though. It dosnt matter if it' WiFi or data either.
Ive seen gliches like this before that usually self resolves @Helen2504
If it does not then if all the settings and preferences settings look Ok then i'd be tempted to clear the cache of the email app.
If no joy I would delete the email accounts off the phone then reboot the phone by turning the device Off and On and then re enter the email accounts back into the phone.
You could also try another email app.
I also have not been able to send emails from my Samsung email app for the past 3 weeks all of a sudden. This has been a major problem for me and I have tried have all suggested fixes like above but nothing is working. My email has worked fine the past 2 years on this phone till now and I have no idea how to fix it.
I had a similar problem and solution was uninstalling Samsung E-mail app i reinstalling it again. Not logging out, but completely uninstalling the app.
I am having the same problem with my S8+. I can receive but not send emails. It has been about a month. I have deleted the acvount and restarted, no good, i have cleared cache and data and restarted, no good. You can not uninstall email on S8+/S8. Tried imap, pop3, and exchange, all no good.
Out of ideas.
Unfontuantly steps one and two were performed after hours working on phone and the account having issue on my exchange server.
2nd step I believe resolved as the out box emptyed, and a send of outbound held e-mail was confirmed.
Had the same issue. It was resolved by contacting the Samsung Help desk. Prior to contacted them, find your server settings from your e-mail provider, both POP3 and IMAP. The Samsung agent will want control of your phone in the process so download this app - Smart Tutor for Samsung. The agent will assure that the settings are correct for your phone. At least it worked for me. If you have the information for the Samsung help desk agent, you'll be able to reply to messages in just a few minutes!
