Accessing a page with a office365 macro will cause a login redirect

[oanalavinia]

Steps to reproduce while logged in with an admin user:

1. Go a page, let's say Sandbox.TestPage1
2. Edit it, add a {{office365/}} macro call and save it
3. Access the page in view mode

Expected result:
The macro works or an error message is displayed in case of problems.
Actual result:
The page is redirected to the microsoft login page

I tested on XWiki 11.10 and 14.4.7, with Office365 1.10 and Microsoft Azure Active Directory Single Sign-On 1.5.7

In case the office365 macro call is actually added on the home page Main, it will cause problems to the XWiki login. After you click on the login button, a redirect is done automatically to the home page and this will now cause another redirect to the microsoft login page. An workaround for this is to try to access a different page and only then to try the login, since the redirect will be done to this page instead of the home page.
