Allow guest access in MS teams for particular domain

I wanted to achieve allow guest access in MS teams for particular domain rather then to allow for all external domains. Ms teams givens option to enable guest access only not any option to add domain...

i agree but still concern is same, if We allowed guest access for two domain from azure then MS teams is needs to enable the guest access, if yes then it would allow for two domain or all domains. if it would allowed guest access for all domains then how AAD would restrict for teams guest access?

Hi Rakesh_Chaturvedi,

Me and my organization is trying to achieve the same thing that you posted here, to allow guest access in MS teams for certain domains. You are also correct that External access is for federation and only applies 1:1 chat or 1:n chat.

But have you tried following adam deltinger response? I did that It worked. Yes, enabling MS teams guest access will allow all domains outside the organisation to be invited as guest in MS teams. But MS teams relies in AAD policy to be specific in O365 groups, by tweaking the allow/block policy in AAD this will override the "Allow all domains" when enabling guest access.

In short enabling guest access in ms teams will allow all domains, but if you manage the guest access to Office 365, you will be able to achieve your goal.

PS. sorry for my bad english.
