Error Code 202

I am having the same issue. Windows 10 and 11. Edge and Chrome. Multiple users. Have tried:
1. Verify Browser Settings:

Pop-up Blockers: Ensure that your browser allows pop-ups for Zoom and OWA. Pop-up blockers can interfere with the authentication process. 

Third-Party Cookies: Some browsers block third-party cookies by default, which can disrupt SSO. Adjust your browser settings to allow third-party cookies or whitelist Zoom's domains. 

2. Update the Zoom Add-in: An outdated Zoom add-in might cause authentication issues. Consider removing and reinstalling the add-in: 

Remove the Add-in: 

In OWA, click on the gear icon (Settings) and select "Manage add-ins." 
Locate the Zoom add-in and remove it. 

Reinstall the Add-in: 

Go to the Microsoft AppSource and search for "Zoom for Outlook." 
Follow the prompts to add it back to your OWA. 

1 is easy and didn't help. 2 instructions are wrong but I did find how to manage apps in Edge and was not able to remove the Zoom app. I am using v 2.10.0.0 of the app like everyone else.
