Technical Description and Importance

Managing sanctioned Teams collaboration domains ensures that Teams communication is restricted to approved organizations. By carefully controlling which domains are added or removed, organizations can enhance control over external communication while enabling essential business operations. This process supports potential compliance requirements and reduces the risk of accidental or unauthorized data sharing. Routine domain management promotes seamless collaboration with trusted external partners while limiting unnecessary exposure to unsanctioned domains.
