Further, I expect this prompt is not limited to email. It could very well apply to anything that is trying to access OneDrive, Teams or even OneNote data.
The problem is that Office 365 has a setting that disables access to data from third party apps and you will need to change it to allow people to setup those apps:

- Click ADMIN
- Click SETTINGS > SERVICES & ADD-INS > INTEGRATED APPS
- Place a check mark in LET PEOPLE IN YOUR ORGANIZATION DECIDE WHETHER THIRD-PARTY APPS CAN ACCESS THEIR OFFICE 365 INFORMATION
