Question: For some reason CRS says “Hey, nothing is scheduled today.”, even though I do have four meetings scheduled. We are using Exchange 2010. In CRS my Exchange URL is set up as  which I can paste into the browser on that machine and it takes me to (which I have also tried as the Exchange URL in CRS), I can see the mailbox – and I can then click on Calendar and my appointments show. 

Answer: It looks like you may be entering in the outlook Web Access url and not the exchange Web services one. They are different and serve much different purposes.  They are also both controlled/enabled by the exchange admin... You may need to contact your exchange admin for the right url. Typically it ends in EWS/Exchange.asmx”.
