Hi @IBN ,
I don't know much about Webex and can not do some tests about the Teams meeting room because I don't have such resources:(
But I found these documents about the Webex meetings on Outlook and Teams, you can see if these could help:
https://help.webex.com/en-US/article/c15vr2/Schedule-a-Meeting-in-Microsoft-Outlook-for-Windows
https://dispatch.m.io/connect-microsoft-teams-cisco-webex/
Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.
Best regards,
Lou
