Outlook Calendar on Samsung Galaxy S7 will not sync I have just bought a Samsung Galaxy S7 (running Android 6.0.1) and installed the Outlook app. Email syncs fine but I see nothing on my calendar. When I tap the top left burger (?) menu "Kevin's calendar" is almost always unchecked. I check it but still nothing shows.

I have also tried resetting my account by going to the calendar settings (cog in the top right, opening my @hotmail.co.uk account and pressing RESET ACCOUNT).

I've also tried uninstalling and reinstalling the app.

It worked fine on my Android S4.
In the hope that this will help someone else.


Uninstall the Outlook app
Go to "Settings" > "Accounts" and remove all accounts relating to hotmail.co.uk
Add a new "Microsoft Exchange ActiveSync" account and enter your details.


Once successful you can view your email by using the pre-installed "Mail" app and you can view your calendar entries by using the pre-installed "S-Planner" app.

If you want to use the Outlook app then follow these further steps


Reinstall the Outlook app
Open the Outlook app and follow the instructions in the setup wizard. Choose "Exchange" account when given a choice between "Office 365", "Outlook.com" and "Exchange".
You'll have to enter your username and password several times and accept all permission prompts.


You should now be able to see your calendar entries in the Outlook app.

(strictly speaking I don't think you need to do step 3 if you carry on doing steps 4 - 6, but I'm not prepared to go through all that again to prove it)
