Having the Host Key change every single day is a HUGE disruption to our business. We have hundreds of week-long classes that run and having to send each instructor a new Host key every day is UNACCEPTABLE. This is a terrible idea. Please change this back immediately.
Host Key Rotation was introduced as a security feature in 40.10
Whilst we do not encourage it, host key rotation can be disabled for your webex site
Please open a service request/TAC case if you wish to disable this feature
Could you please provide some details around what type of meeting you are scheduling, where are you scheduling the meeting from, and are you using recurring meetings and creating exceptions to the recurring meeting?
