As long as you created a Team Today account by using the Office 365 or Google sign up button on the website it should instantly work with no need to change settings.
It's important during sign up with Office 365 or Google that you allow Team Today edit access so it can write the events to your calendar.
You can also check that you are receiving emails in the Settings area of Team-today.
Whilst logged into Team-Today.com go to Settings > Personal Preferences > and make sure that “Add events to your work calendar” is switched on.
If you are still having issues then you may have created an account with a personal email and password during sign up. If that's the case then we’ll need to get you swapped over to an Office 365 account or Google account. Contact us at email@example.com
