Contact people outside the company

If your employees often work with people from other companies, you can add them to contacts or give them access to corporate communication channels.

External contacts

To enable your employees to find people from other companies in Yandex Mail, Calendar, and Disk, you can add them as external contacts. Such contacts won't have access to the corporate data — they'll just appear in your contact list. How to add contacts

Guests

Guests are people outside your organization who can join work chats in Yandex Messenger. You choose which chats to add them to. They can't message employees on their own, create chats, or leave them. To add a guest to your company, send them an invitation. How to invite

Federations

To enable smooth communication between employees from different companies on work-related issues, join the companies in a federation. The employees of these companies will gain access to shared contacts in Yandex Mail, Calendar, and Messenger. How to create a federation
