Setting External access options via powershell
Hi. I'm trying to set External access for Teams, but via powershell. Specifically the "Users can communicate with Skype users" option. I can successfully set the "Users can communicate with other Skype for Business and Teams users", but I can't find a solution for the other option ("Users can communicate with Skype users"). I have read numbers of blog postings, tutorials for the mentioned subject but it just doesn't work, the option won't switch. Most mentioned powershell command for doing it, is the following: Set-CsExternalAccessPolicy -EnableOutsideAccess $False Set-CsExternalAccessPolicy -EnableFederationAccess $False Set-CsExternalAccessPolicy -EnablePublicCloudAccess $False Set-CsExternalAccessPolicy -EnablePublicCloudAudioVideoAccess $False And while the script changes the targeted parameters successfully, the switch in the GUI still remains in "ON" position. I Have set the switch to the "OFF" position by hand, but underlying parameters quoted in code block above, haven't changed (their values retrieved with Get-CsExternalAccessPolicy powershell command. So, from that, it seems that those commands aren't for that option after all.. Any help is appreciated. Br
Security Researchers Demonstrate Exploit Against Teams External Access
Security researchers JumpSec demonstrated a weakness in Teams External Access by showing how to send malware to users via a federated chat. The exploit depends on another weakness in that attackers can interfere with the set of policy controls transmitted by the Teams server to clients. It’s yet another reason why Microsoft 365 tenants should restrict external access to the set of domains they really want to chat with. https://office365itpros.com/2023/06/26/teams-external-access-exploit/
SharePoint Online External users redirected to ADFS sign-in page
Some of our external users are experiencing weird behavior when trying to sign-in. Login flow is "User browse the site url --> enter their external signin address --> Choose 'Microsoft Account' as the account type --> Enter their password --> They get redirected to organizations ADFS sign-on page --> user enter their password and keep getting the wrong userid or password message. I have checked in AAD portal and user is added as a 'Guest'. However, I can't understand why user is getting redirected to ADFS SSO page. As an external user with Microsoft account, user should authenticate with Microsoft Live ID, not with ADFS.
Not able to find external users from my organizational teams account
Hi, I'm not able to find external users (personal account) from my organizational teams account. I typed the mail address on the To box in Create a chat window. And clicked on Search for the mail externally. Still couldn't find the account. I have added screenshots of both the accounts. Am I doing something wrong to find the external user.New External Sharing Experience
Good day I have shared a library in SharePoint online with an external user, the user logs in with his Microsoft account and can access the documents, however he can only open a document in the browser and not in excel or word directly to edit. the Library and site collection is set to open in client application. External user has edit permissions. Our company is using Office 365, is there a way user can edit directly in client application and not online? Also would it be possible for the user to sync the shared library? Thank you
