How to connect Meeting Room Schedule in a Exchange Hybrid environment?

You can connect to your Microsoft 365 (formerly known as 0365)/Microsoft Exchange resource calendar using multiple options. The Meeting Room Schedule allows you to connect to a calendar associated with a user account as well. This entry shows how to connect to a resource directly. The direct method to connect to a resource to Microsoft 365 (formerly known as 0365) or Exchange is described here. It’s very straightforward and should work for 90% of business environments. It needs a visit in the 0365/Exchange directory where resources are listed and delivers the credentials needed by the door display solution. Reset the password and you’re done. The average skilled Administrator should be able to do this within 5-10 minutes. Check our blogpost about Delegate Access if you prefer to connect using a more advanced concept. If the user is not allowed to give consent, and admin approval is required, then how to send an approval request is described here.
