Is there any way to share contacts between 2 seperate Tenants

Question

Our company is doing frequent business with another company, and it would be greatly beneficial if we could see a contact list of users from their directory.

Does B2B or any other Microsoft Solution make it possible to sync/search contacts between 2 tenants easily? Some way to make collaboration between the two organizations more seamless and search for each others users in Teams and Outlook.

Take a look at the recently announced Cross-tenant sync feature: https://learn.microsoft.com/en-us/azure/active-directory/multi-tenant-organizations/cross-tenant-synchronization-overview
