i cant friend someone who i deleted his contacts

Hey @Griffpatch_zoom were they an internal or external contact when added? And apologies for the delay in response, are you not able to re-do the following:

1. Click Invite a Zoom Contact.
2. Enter one email address at a time.
3. Click Invite.
   • If the person has a Zoom account, they’ll receive a contact request within their Zoom Chat client. Once they accept the request, you can start chatting with them.
   • If the person doesn’t have a Zoom account, they’ll receive an invite email. Once they sign up for Zoom, they’ll be added to your contacts directory so you can chat with them.

Were they an internal or external contact when added? 

Hey @Griffpatch_zoom, just reaching out on my reply! Was this helpful? If so, great! Just don't want you to forget to click the Accept as Solution button. Otherwise, more than happy to help further troubleshoot!
