Error 4503

I just started getting the same errors today, never have had this problem before. I got a message that recurring meetings have to use a generated code and not a personal ID in order for an occurrence to be changed.

The basic things you can try are:

Check your Internet connection.
Power cycle your devices.
Check for Available Zoom App Updates.
Reinstall the Zoom App.
Join in a Browser.
Go into your Windows Firewall setting and changing the protocol for TCP 6 and UDP 17 and changing them to ANY.
Create a new Windows account.

I am getting this same error did you ever figure this out? 

I'm getting the same error when trying to reschedule one instance of a recurring meeting. The recurring meeting was already using a generated code and not a personal ID. 

I am also getting this same error when trying to change one meeting instance of a recurring meeting.  

I am getting the same error. Any suggestions yet?

Hi everyone!

Can you please provide the version of Zoom that you are currently running so that we can investigate further? Thank you!

I had the same issue but only with old weekly meetings. the new ones worked fine.

I first uninstalled the Zoom Client and then tried to edit ONE of the weeks and it worked. then I installed the latest Zoom Client and it worked too.
