Find Guests in Office 365 Groups and Teams Where Guests are Prohibited

You can apply an Office 365 Sensitivity Label to control different aspects of Groups, Teams, and Sites. One of the settings controls whether guest users are allowed in group membership. We explain how to use PowerShell to search groups assigned a label to block guest access for existing guests, just in case you want to remove them.

Teams Removes System Messages from the General Channel

Teams is removing system messages from the General channel in teams. System messages tell users about events like new members, but they’re really not that interesting, unless you’re fond of tracking the comings and goings of members, much like a noisy neighbor behind a curtain. Uncluttering the General channel is no reason to let it degrade, so keep it for important stuff and force conversations into other channels.

Why Teams Can’t Schedule Meetings with (Some) Teams

You can use Microsoft 365 Groups and distribution lists to schedule meetings in the Teams calendar app, but sometimes you can’t schedule meetings with Teams. That sounds odd, but it’s because of the way that Teams selects groups from the Exchange Online GAL to show to users in the “picker” control to select meeting attendees. You can make changes to have Teams show up in the GAL, but that might not be enough if you want everyone in the team to receive meeting invitations.

Teams Meetings and Group Chat Limit Increased to 300

Microsoft is raising the limit for Teams meetings and group chats to 350 participants. The group chat limit was increased to 250 in early May. The new increase is temporary and Microsoft will review it in September to decide whether to keep it at 350. The update is already rolling out and should be available worldwide in mid June.

Limiting Who Can Present in Teams Meetings

A new setting available in Teams meeting policies allows Office 365 tenants to have per-user control over who can present at meetings. You might want to do this to stop guests presenting. or to limit some people from inviting others to present. I’m not quite sure what the use case is, but no doubt some people will find great value in the new setting.

Using Microsoft Whiteboard with Teams

Whiteboard is a digital canvas application that can be loaded into Teams meetings to allow participants to share and develop ideas. The app available in Teams isn’t the most functional way to interact with Whiteboard, what whatever version you use can draw and sketch ideas to share with team members and other people within an Office 365 tenant.

Using Teams Compliance Data for eDiscovery

For compliance purposes, the Microsoft 365 substrate captures copies of Teams messages in Exchange Online mailboxes. The compliance records are indexed and discoverable, which means that they can be found by content searches. However, Teams compliance records are imperfect copies of the real data, which is a fact that seems to have escaped many people.

Teams Improves Analytics in Desktop and Browser Clients

An item in the Teams release notes tells us that analytics are now available for channels. You can find out how many topics and replies are posted within a channel. You’ll probably know what channels are in heavy use anyway, but seeing how little traffic some channels get is a good way of knowing that maybe your teams don’t need those channels.

Teams Meeting Recording Fails Without Stream License

It’s very convenient to be able to record a Teams meeting and have the recording processed and stored in Stream. But what happens when the recording fails to be processed? Usually it’s because the account that starts the recording (the owner) doesn’t have a Stream license. Fortunately, the situation is easily rescued.

Microsoft Delivers Control for Teams Background Blur and Effects

Microsoft has updated the Teams meeting policy to introduce a new control over video filters in Teams meetings. The VideoFiltersMode setting controls if people can use background blur and background effects, including the ability to upload custom images. A client update is needed to respect the new setting. It will come at the end of May.
