How To Fix Samsung Galaxy S9 Cannot Send Email After Android Pie Update

Problem: Hello, Since last week, I am facing an issue on a S9, updated with Pie, and the samsung mail app. Here are the details of issues and all I tried already to fix it… any idea on how I could then fix the issue, without the need of changing mail app? (as I liked the features of the Samsung one)… *3 accounts set up on the Samsung email app, 1 is exchange activesync (so main), 2 in imap *the 2 imap account work perfectly (send/receive). *exchange activesync is receiving emails, contacts are synchronized, calendar synchronized BUT impossible to send any email. They stay stuck in the sending folder (outbox), if I am forcing the send, then it tries to send for hours but nothing is going out. I then need to restart app to use it again.

I tried:


  • *restart phone: no success
  • *delete accounts and recreate them: no success
  • *empty cache + data app then reinstall account: no success
  • *internet connection OK, issue in wifi and 4G
  • *activesync supplier contacted and have no found issues on their side
  • *exchange mailbox OK on webmail
  • *installed another mail app (gmail, mail one, outlook): exchange account worked perfectly with all of them (but then more difficult to synchro correctly calendar)

Any idea on fixing then this bug which seem linked to the Samsung native mail app? Thanks a lot. Best Regards

Solution: Before performing any troubleshooting steps on this phone it’s best to make sure that it is running on the latest software version. If an update is available then I suggest that you download and install it first.

As this issue is most likely caused by a software glitch we will be concentrating our troubleshooting efforts on the software side of the device. Follow the troubleshooting steps listed below which are recommended for this particular problem.

Perform a soft reset

The first thing that you will need to do in this particular case is a soft reset. This will usually fix issues caused by minor software glitches as it will refresh the phone software. This is also called as a simulated battery pull as it disconnects the phone from the battery.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Check if the issue still occurs.

Clear the cache and data of the Mail app

There’s a possibility that the problem could be caused by corrupt temporary data within the Mail app. You need to get rid of this data by clearing the cache and data of the app. Once this is done you will need to setup your email accounts again.  

  • From the Home screen, swipe up on an empty spot to open the Apps tray.
  • Tap Settings > Apps.
  • Tap the desired application in the default list.
  • To display preinstalled apps, tap Menu > Show system apps.
  • Tap Storage > CLEAR CACHE > CLEAR DATA > DELETE

Setup your email again then check if the issue still occurs.

Check if the issue occurs in Safe Mode

An app you downloaded in your phone could be causing this problem. To check if this is the case you will need to start the phone in Safe Mode since only the pre-installed apps are allowed to run in this mode.

  • Turn the phone off.
  • Press and hold the Power key past the model name screen appearing on the screen.
  • When SAMSUNG appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

In case the issue does not occur in this mode then it’s likely that the problem is caused by an app you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

The phone system cached data is used to speed up the access to your phone apps. Sometimes this data can get corrupted which results in issues occurring on the device. To check if a corrupted cached data is causing the problem you will need to wipe the cache partition of the phone from the recovery mode.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key to highlight “wipe cache partition.”
  • Press the Power key to select.
  • Press the Volume down key to highlight “yes” and press the Power key to select.
  • When the wipe cache partition is complete, “Reboot system now” is highlighted.
  • Press the Power key to restart the device.

Check if the issue still occurs.

Perform a factory reset

One last troubleshooting step you should consider is a factory reset. This will revert your phone back to its original factory condition. Make sure to backup your phone data before doing the reset as it will be deleted in the process.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

After the reset you will need to setup your email again. It’s very likely that the problem will be fixed by now.
