This blogpost is more a note to self, but sigh, I hate it when it does this…. show the 412 Cookies are Disabled error message when trying to open the Exchange Admin Center (EAC) in Exchange Online:
I’m not sure if this issue shows up every time, but at least it shows up when you want to configure an Exchange Hybrid Configuration and you select Hybrid in the On-Premises EAC and select Sign In to Office 365.
To solve this, select the Tools menu in Internet Explorer, select Internet Options and click the Privacy tab.
Lower the slider just one click to Low and click Apply or OK.
Now when you refresh the page in Internet Explorer it should continue with the Hybrid Configuration page:
In my previous blog post I explained about an Exchange 2013 hybrid configuration, and what the prerequisites are for such a configuration and how to implement and configure one (or more) Exchange 2013 Hybrid servers.
In this blog post we’ll continue with the Hybrid Configuration and we will run the Hybrid Configuration Wizard (HCW) to actually create the Exchange 2013 Hybrid configuration.
Note. For simplicity I assume your Exchange 2013 is fully operational without any (certificate) issues on the Internet, which means you have configured all your Virtual Directories, Outlook Anywhere and Autodiscover. Everything must be working correctly to prevent any issues during configuration, possibly resulting in a misconfigured and not working hybrid configuration.
Run the Hybrid Configuration Wizard
Configuring Exchange 2013 is relatively easy and can be started from the Exchange Admin Center (EAC). The wizard that’s used here is known as the Hybrid Configuration Wizard (HCW) and in my experience a very stable (although there have been some glitches with the HCW in earlier CU’s of Exchange 2013) and efficient wizard, providing you have met all prerequisites of course.
Login to the Exchange 2013 Hybrid server and start the Exchange Admin Center locally. The reason for doing this locally on the server is that during the wizard some additional software needs to be installed for the OAuth part of the Hybrid configuration.
In the Exchange Admin Center in the navigation pane select hybrid. In the hybrid setup window click the enable button to initially enable the hybrid mode in your organization. The option My Office 365 organzation is hosted by 21Vianet should be left unchecked. Office 365 in China is hosted by 21Vianet so this option does not apply to us (unless you are in China and your organization is hosted by 21Vianet of course).
