New teams created using Teams clients are hidden from Exchange Online, but those created using administrative interfaces are not. The result is potential confusion. in this post, we describe a PowerShell script to find any team-enabled Microsoft 365 Groups which are visible to Exchange and hide them. It’s easy scripting, but you need to run the script periodically to update the settings for new teams.
How do you create a report of all the Teams in a tenant and their SharePoint Online sites? As it turns out, a two-line script does the job. We make the script slightly prettier, but it’s still simple. And because it’s PowerShell, anyone can change the code to make it work the way they want it to.
Microsoft is changing the way new teams are created in the Teams admin center to make sure that their settings are consistent with teams created in other interfaces. It’s a good idea because it means that all teams are then created equal. Organizations who wish to use different settings can update teams once they’re created using either PowerShell or the Graph API.
Microsoft 365 Groups are used by applications like Teams and Yammer. The PowerShell Get-UnifiedGroup cmdlet finds groups, but can it find the groups enabled for Teams and Yammer? Here’s some idle musing on the topic which might or might not interest you.
The Microsoft Graph collects huge amounts of signals about Office 365 user activity. Some of that data is used to generate insights into information that might be interesting to users. You can already disable insights in Delve, and now Microsoft allows you to disable insights elsewhere in Office 365. The downside is you’ve got to patch the Graph organization settings to limit insights, and that might just be outside the ability of the average tenant administrator. Unless they use the Graph Explorer to do the job.
Once Microsoft 365 Groups and Teams reach the end of their useful life, it’s good to archive them so that their data stays online and available for eDiscovery. A recent request looked for help to archive 600 Groups at the end of the academic year. The script described here might help solve the problem.
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.
PowerShell is a great way to get work done with Office 365 data. The downside is that PowerShell can sometimes be slow, which is why we look for ways to speed things up, especially when dealing with some of the “heavier” cmdlets like Get-UnifiedGroup. The good news is that switching loops to use the ForEach method can speed things up. The bad is that you might only squeeze an extra 5% performance out of your code. Is that enough to bother? Your call…
It’s easy to create a list of group-enabled SharePoint Online sites using the Get-SPOSite cmdlet. But it’s much more interesting to probe a little deeper to uncover extra information about the group using the GroupId property returned if you specify the Detailed parameter. This post explains a PowerShell script written to examine the possibilities, including how to highlight sites belonging to deleted groups that are kept by retention policies.
One of the great things about Teams is the way that it orchestrates Office 365 resources like SharePoint Online sites. The downside is that a tenant’s valuable SharePoint storage quota might be absorbed by a profusion of Teams. To offset the problem, you can apply lower limits to sites belonging to Teams and the best approach is to use PowerShell for the job.
Every Office 365 group (and team) has a SharePoint site. But how to find the URLs of all the sites used by teams in a tenant. One PowerShell answer came from Syskit, but it’s an old technique and we can do better now by fetching a list of teams in the tenant and then retrieving the URL for each team-enabled group.
A reader asked if it is possible to add an administrator account to every Office 365 Group. This feature doesn’t exists OOTB, but it’s an easy task to script with PowerShell.
