I implemented the Azure AD SSO on mobile apps and used ADAL Nuget package. I had few queries from my clients on the expiration of the refresh-token. After going back and forth with Azure Engineering team, and trying few things, here are my findings. I have documented the details in a blog post here:

1. Azure AD SSO Access-Token expires in 1 hour.
2. You could use Azure AD Refresh Token to refresh your AccessToken.
3. The Refresh Token expires in 72.
4. Azure allows an access-token to be refreshed using the refresh-token for a maximum period of time of 90 days (from the initial date of issuing the token). This means after 90 days, Azure will authenticate the user to login again. (Cannot confirm any changes to this)
5. The expiry time of the refresh token is set to 72 hours by default. This is now configurable. You can change this value as per the discussion here
