Hi,
Failed to add two specific email addresses. An activation email was just not sent to them.
According to a check in the firewall, the email is not blocked and does not enter spam. IPs 198.2.179.123, 198.2.179.168 and 198.2.179.86 already in whitelist in FW. I also do not see any attempt in logs to open incoming session from these addresses. 
All other users in the same domain have successfully activated their accounts.
I also have two extra licenses so it is not a problem of licenses.

I have been teaching piano/keyboard lesson using Zoom, as well as given many lectures for Yamaha using my digital piano. Last Wednesday and Thursday I was unable to hear my students instruments, and they were unable to hear mine. I would hear about 4 notes, then everything was gone. I could hear them speaking perfectly, but no instruments. I use a Windows 10 computer, and all students were on iOS devices. I pay extra for this service, and don't use the free service. What has changed, and what do I need to do to be able to teach successfully again? This is a real problem. Thank you! Lori

Even starting this topic is frustrating! I was trying to do a webinar today but because of the echo and reverberation, had to cancel a presentation minutes in. I have a MacBook and in order to play audio not only from myself but from the Keynote presentation I have used Loopback flawlessly until recently.

Got error code 10004 so I uninstalled and reinstalled Zoom. Still SIGNIFICANT echo and reverberation. I need to be able to use audio from my mic, Keynote and Quicktime player for audio and video - WITHOUT echo and reverberation. 

Can anyone help solve the problem, or does anyone know of a company/person that could troubleshoot these issues for me?

Thanks,

Just bought a new laptop and had my first Zoom meeting with it yesterday. Backgrounds were easy to set up but then I wanted to re-activate the Filters and Studio Effects I've been using for several years. They're gone!! And, when the software attempts to install updates, there is a fail error -- I think the number is 10004. I've already checked to be sure that Zoom is allowed access to the Downloads folder and it is.

I just installed Ventura. Is Zoom not up to speed?
