Teams Room "Cannot Fetch Calendar"
Good day,
I have just finished setting up our Lenovo ThinkSmart Hub500. Creating the room and users account as per MS instructions is all done and Teams Room is logged in. I can start a new meeting and project but no meetings are showing up. At the top it says "Cannot Fetch Calendar".
What are we doing wrong?
Thanks.
Hi,
Are you running Exchange Online or if you are running Exchange On-Premises are you running a version later that Ex 2013? It could be DNS problems, that your MTR can't connect to autodiscovery for Exchange.
- Hello,
We are running exchange online. Do we need to change anything?

Hello, I hope you've solved your problem.
Just to provide you additional information.
The main cause is that your Microsoft Teams Room has no access to https://outlook.office365.com/ews/excahnge
A good way to analyse is to follow the potential causes provided by Jimmy Vaughan

I've encountered another cause
The root and intermediate root certification of the https://outlook.office365.com certificates were not trusted. Add them to you Trusted Root Certification Autorites and Intermediate Certification autorities.
I tried to solve it in various ways and I found quite a bit of material If using the Local Network it does not connect and it says calendar error, I tried it with another network, (sharing from my cell phone, which is open network), and if the error does not appear, it is DNS of the local Network adapter, the internal DNS, justo changing the DNS for 8.8.8.8 it´s fineIf the problem continues, it is not the local DNS, it is in external DNS in other cases, how to know, creating an account in the native domain @ onmicrosoft.com, if it does not give a calendar error, it is then the external DNS linked to the domain account @ domain from company.com, usually the problem is in the autodiscover

I have been struggling with exactly the same problem and have gone through all the instructions on the internet without success....
After running the teams connectivity test I came to the conclusion that the SSL certificate from the domain controller is not installed.

After installing the SSL certificate on the device I was able to access the Teams calendar.- I have the same problem . how to installing the SSL certificate.
- You need to head into the desktop admin side of the MTR to install the cert. It should be deployed when domain joined IIRC.
