You sign in to the Office 365 portal in Office 365, and then you try to access the Exchange Admin Center. However, the Exchange Admin Center isn't displayed on the page as expected. Instead, you experience the following symptoms:
  • The Exchange Control Panel from the earlier version of Office 365 is displayed on the page.
  • The web browser session doesn't show your user account as the user who is signed in. Instead, it shows the last user who signed in and accessed the Exchange Control Panel.


Access to the Exchange Admin Center is processed as a separate sign-in. By default, credentials from the existing web browser session are used to access the Exchange Admin Center. If the current browser session was used to access the Exchange Control Panel in Office 365, the Exchange Control Panel is displayed again when an administrator accesses the Exchange Admin Center in Office 365. This behavior occurs even if the administrator who had previously signed in explicitly signed out of the Exchange Control Panel. 


Use a new web browser session when you sign in to Office 365. To do this, do one of the following:
  • Close all web browser windows, and then open a new browser window from which to access the Office 365 portal ( for Office 365. 
  • Use a new InPrivate Browsing session to access the Office 365 portal for Office 365. For more information about InPrivate Browsing, go to the following Microsoft website: 
    InPrivate Browsing
