Administration Mode Enabled. Only system administrators and system customizers can sign in at this time in CRM 2015 Online.


After we copied our Dev instance to another Sandbox instance we got this message on opening CRM.

To disable it.

Go to Office 365 Administration Section

Select your sandbox instance.

Select Admin

Uncheck Enable Administration Mode

Hope it helps.
