Our company has recently moved to Office 365. When I try to login from home I come to the correct login page:

When I try to login from within the company I get this page:

- It's impossible to login from this gray site. It never accepts my password.
- This is regular Office 365 (i.e., but it uses our company login.
- Both machines has Mojave 10.14.6 and no Safari extension. And exactly the same Safari preferences (I've even tried on a guest user)
- The login works perfect with Chrome and Firefox (it shows the correct login page, not the gray site).

Does anyone know how I could troubleshoot this? I'm basically the only Mac user so I can't check with other folks.

If the login works with Firefox,
DOES NOT work with Safari,
Use Firefox to login.
