Limiting SharePoint Storage for Teams

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.

How to Rename the Site Address (URL) for a SharePoint Online Site

The modern SharePoint Admin Center introduces the ability to rename the URLs for SharePoint site names. This responds to a longstanding customer request and makes it possible for site names to reflect what users see elsewhere in Office 365 groups or Teams. It’s a small but welcome change in the fit and finish category.

Teams Admin Center Adds Delete and Archive Capabilities

The Teams Admin Center now boasts the ability to delete teams and (if you don’t want to get rid of them altogether) archive teams. And unarchive teams back into use. All is good, even if Microsoft is making slow progress at building out Teams management functionality. Some of the slowness is due to dependencies, some because of other factors.

Finding the SharePoint URLs for Teams

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.

Existing Guest Accounts and the Azure B2B Collaboration Policy

When you impose a block on certain domains, you’d like to think that applications like Teams will respect that block. As it turns out, if you have some lingering guests in your Azure Active Directory, the B2B collaboration policy might not be as effective as you’d hope.

Microsoft Makes Org-Wide Teams Available to Office 365 Tenants

The latest version of Teams supports the ability to create org-wide teams, but only if your tenant has fewer than 1,000 accounts. It’s a neat idea, if you can use it, but if you have more than 1,000 accounts, there are other ways to foster company-wide communications.

Synchronizing AAD Security Groups with Office 365 Groups

Security groups are often used to protect access to resources, but they can’t be used to control membership for Office 365 Groups or Teams.

PowerShell is available to do the job, and as it turns out, it’s not too difficult.

Office 365 Groups and the ProvisioningOption property

Some will tell you that you can figure out what resources an Office 365 Group is connected to by checking the ProvisioningOption property with the Get-UnifiedGroup cmdlet. Well, you can’t. If you want to do something like check for team-enabled groups, you’ll need a different approach.

Enabling Access to Teams for Guest Users with PowerShell

During transitions, things sometimes don’t go so smoothly. Such is the case if you want to enable or disable guest user access to Teams and find that the setting to control the access is no longer available in the Office 365 Admin Center. But PowerShell can control the setting, so that’s the solution to the problem.
