Teams, Block Access to Remote Tenant\Teams

We have noticed that some teams users have been receiving invites to teams sites on a different tenant.

 

It is expected that the Tenant is being used for various phising attacks, I dont want to block users from accepting invites to third party tenant\teams site, but need a way to:

 

- track this activity

- block this activity, if we suspect there is a problem

 

I suspect the answer is a combination of things, is there a specific way in which this can be achieved.

 

Thanks

    Hi, no clear answer here AFAIK. It would have to be a combo of things, as when tuning phising etc. https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/tuning-anti-phishing?view=o365-worldwide

    I’m aware of a couple of UV requests, one of them here https://microsoftteams.uservoice.com/forums/555103-public/suggestions/36352375-prevent-users-from-joining-external-tenants-as-gue
