Exhange ECP, I can't get into the admin panel, what's the reason?

Question

Microsoft Exchange

When I log in to https://email.example.com/ecp , I'm redirected to my profile settings page, not to the admin panel.
Until today everything was ok.
Where to look?

Answer 1

autodiscover settings

Answer 2

Because you were deprived of your rights. Or limited.
PS
If you are an admin, then add yourself to the "Organization management" group. If not, ask the admin.
