Developer Tenant External User Messaging Issue
Hi everyone I have a Microsoft 365 Developer Tenant which includes 25Microsoft 365 E5 Developer licences. I have been messaging a friend who is external to this tenant and it has been working fine up until around 2 weeks ago. Having looked into it, this seems to have coincided with Microsoft enforcing the policy to block federation with Teams trial-only tenants. Am I right in thinking that my developer tenant is considered a trial-only tenant in this instance?Cannot Leave Foreign Organization / Group
Hello, I was added to a university organization for a meeting with my personal email address. After speaking with the group founder, he removed my user from the group. The group founder is not the admin of the organization. Afterward, I noticed the following changes: My Teams still shows the foreign organization. The button to leave the organization is now active, and I can click it. Previously, my personal email address was visible, but after leaving the group, I now see a different email address. Now the interesting part: To sign out of the organization, I need to log back in. However, this does not work with my personal email address, but it does work with the address that became visible after I was removed from the group. Unfortunately, I don’t have a password for this address and no way to reset it. The group founder doesn't know what else to as he doesn't see my user nor my email address in the system anymore. What can I do?
How to Improve Security in Teams to Prevent Unauthorized Recordings and Anonymous Access?
Hello, We’ve faced multiple incidents in Microsoft Teams sessions where unauthorized AI recording apps were activated, and anonymous users joined. We’ve tried using Lobby Mode, restricting recording permissions, and blocking third-party apps via App Permission Policies. However, these measures have limitations, such as requiring constant monitoring of the lobby and users returning after leaving. Are there additional features, configurations, or third-party tools within or beyond Microsoft Teams (e.g., Teams Premium) that can provide robust security to: Automatically block unauthorized apps during sessions? Prevent reentry of removed participants? Enhance privacy while minimizing the burden on presenters? If Teams cannot address these, what alternative platforms offer better security for large 1-to-many sessions? Thank you!
How to remove cached guest account data from teams
Hi. We have a problem with cached external organization guest account data with some of our users. The problem is that users from an external organization have been using our teams with guest accounts and everything was fine until this external org had to start a new tenant while continuing to use their old domain suffix. Obviously their old guest accounts stopped working in our tenant after they switched in to their new tenant, but the problem is that even after we have deleted their old guest accounts from our Entra ID some of our users are not able to invite them as new users. The old guest profiles of this external org are cached somewhere in our users teams and when they try to invite users from this external organization again, the teams client (Desktop and Web) just digs up the old guest account info from somewhere and the invitations fail. If some one who has not been working with the users from this external org before are able to invite users from that org. We have tried to clear the teams cahce (both the classic and the new) but that doesn't clear those old guest account infos from the users teams. Of course we could invite them from the Teams management portal etc, but there are lots of them and the best solution would be that we get that cached guest account info cleared from the users that are affected by this, becaouse they are the ones who know who to invite and in to which team. -Tomi AaltonenRemoving guest account from Teams personal
Hi, I was once a long time ago added as a guest to my now-previous employer's Teams, via my personal Teams account (using an@live.com account).However, the employer is not longer trading and I cannot get them to remove me as a guest. Until recently this was not a problem as it was just another option hidden away in a menu that I could ignore. However in the last week, Teams has defaulted to using this guest account so I have been trying to delete this guest account from my account. All of the solutions I can see rely on on accessinghttps://myapps.microsoft.com(e.g.https://myapps.microsoft.com), but as my personal account is not valid for that site, I am hitting a brick wall. Please could you advise how I can either fully remove this guest account from my account, or at least stop it being selected as the default app for Teams? It's frustrating that in order to use my own Teams now, I have to have two separate Teams windows open!
Creating a link to opt-in to Teams Meetings/add to Outlook calendars
We're a trade union and host a number of meetings each month that we advertise to our members. Our members list is confidential, so we can't add members to the events in the way you normally would for work events. Instead, we create a teams meeting and invite the named officers (whose membership is public knowledge). We then copy the meeting link to each of the meetings and send them to members via email. Members then have to remember to manually add this to their Outlook calendars. Some use out-of-organisation emails to access these meetings. With the barrage of emails that are sent, many forget to add meetings to their calendars and then subsequently forget that the event is happening. Is there a way that colleagues could add themselves to an invite? Is there a link or perhaps power automate tool that could add this event to their diaries if they were to click a link that we sent? It would need to be opt-in as some don't want their membership known and don't attend meetings.
How to ensure all "Guest" participants can join Teams meeting as "External" instead of "Unverified"
I run a Teams meeting w/security setting "People in my org, trusted orgs, and guests" can bypass lobby. The meeting link is added to an Outlook meeting and sent to people outside my org. All the external users are members of a MS Entra group owned by my org. Some of these externals can join the meeting properly - by credentialing via MS Entra, bypassing the lobby, and entering with (External) next to their name. Others however cannot bypass the lobby and have (Unverified) next to their name in the Teams meeting. What is missing for the Unverified users (they should be the same as the External users)?
