Question

Answer 1

I captured the calls to Azure Active Directory (AAD) with Fiddler and found a JSON response that included the access_token, expires_in and expires_on, id_token, refresh_token, resource, scope and token_type (Bearer).

The expires_on equals 1398790050. So I went to Wolfram Alpha, queried how many seconds this was after 1970 and added 2 hours (I'm in the UTC+2 time zone). The access token is valid for 1 hour. In the TechNet forums it is mentioned the expire token is valid for about 80 days.
