Hi.
I'm Pizzalover28 and I will be glad to be assisting you today.
Are both your zoom and outlook versions up to date?
If not, please update them.
Aditionally, you can try uninstalling and reinstalling both apps again, or rebooting your computer.
Also, it may be good to check if your computer's software is up to date too.
Kind regards:
