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. https://outlook.office365.com/owa/), 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.
