I have a Samsung Galaxy S8 with Android 7.0 installed.
An exchange account is configured with push notification using the Samsung Email 18.104.22.168 app.
When I receive emails I get a notification and if I read the email on my phone the notification goes away.
If I read the email from another device the notification does not go away and my phone keeps indicating that I have a notification by flashing an LED.
Exchange is configured to sync with my phone via push.
Someone else had a similar question but it is now out of date as it was asked in 2010: Exchange Email Notification doesn't clear
How can I configure my phone so that if I read the email on another device the notification goes away?
