Allowing external users in Teams and the security issues

I need to share groups I created on teams with my clients who are external users to the exchange server.

However our IT team is concerned about security and do not want to allow me access to invite guests to the groups.

Can you maybe explain the real risk in security and if it is a concern or not.

Kind Regards

Hi IIse,

The guest experience has limitations by design. There are many functionalities that aren’t available to a guest in Microsoft Teams:

 1.    OneDrive for Business
 2.    People search outside of Teams
 3.    Calendar, Scheduled Meetings, or Meeting Details
 4.    PSTN
 5.    Organization chart
 6.    Create or revise a team
 7.    Browse for a team
 8.    Upload files to a person-to-person chat
 9.    Currently, Teams supports only State 1 and State 2 types of guest users as defined by Azure B2B

For a full list of what a guest can and can’t do in Teams, you can refer to this link: https://docs.microsoft.com/en-us/MicrosoftTeams/guest-experience#comparison-of-team-member-and-guest-capabilities.

With guest access, organizations that use Teams can provide access to teams, documents in channels, resources, chats, and applications to their partners, while maintaining complete control over their own corporate data. All guests in Teams are covered by the same compliance and auditing protection as the rest of Office 365, and guests can be managed securely within Azure AD.
