Change to Outlook Groups Displays High Unread Counts

Outlook for Windows has supported Microsoft 365 Groups since 2015. The developers chose a seen/unseen model for Groups, but now Outlook has switched to a read/unread model, meaning that the unread counts for Groups can suddenly seem much higher than before. It’s a one-time change that aligns Outlook desktop with OWA and Outlook Mobile and there’s an easy way to set all unread items to be read. But you might want to tell people that this change is coming!

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.

Reporting Office 365 Group Deletions

Office 365 Groups (and their underlying teams and sites) can be removed by user action or automatically through the Groups expiration policy. By examining records in the Office 365 audit log, we can track exactly when groups are soft-deleted followed by permanent removal 30 days later. All done with a few lines of PowerShell and some parsing of the audit data held in the records.

PowerShell Activity Report for Microsoft 365 Groups and Teams

After a couple of years, it’s time to update the Office 365 Groups and Teams Activity Report script. Written in PowerShell, the script analyzes the groups in an Office 365 tenant to figure out if each group or team is in active use. Because it’s a PowerShell script, you can amend the code to your heart’s content.

Office 365 Groups to Support Sensitivity Labels

At the Ignite 2019 conference in Orlando, Microsoft announced that Office 365 Groups will soon support sensitivity labels, but only to mark group containers with levels of sensitivity. The actual content of the containers, like the messages in Outlook Groups or Teams, will remain unaffected by the labels. For now.

Teams to Support Federated Guest Access for Gmail Accounts

Teams supports federated guest access for Gmail accounts using the identity provider framework of Azure B2B Collaboration. Office 365 tenants must first decide if they want Gmail accounts as guests in all or some teams before going down the federation route. Why Teams and not other Office 365 apps? It’s all to do with the endpoint used by the client to connect. If it can handle federation, all good. If not, it’s standard Azure B2B Collaboration.

Office 365 Groups, Send As, and the Missing NDRs

You can configure Send As and Send on Behalf of permissions to allow Exchange Online users to send messages for an Office 365 Group. All is well if the messages arrive, but if they don’t, the NDRs might not get to where you think they should go, such as a folder in the Recoverable Items structure. That’s OK if the sender was told that a problem exists with a message, but they don’t know anything happened.

New OWA Includes Office 365 Groups Management Interface

The new version of OWA boasts new abilities for owners to manage Office 365 Groups. The new UI is pretty slick and a welcome upgrade to the previous capabilities. You’ll still need to revert to PowerShell to manage some aspects of Office 365 Groups, but not as many times as you used to.

Managing Office 365 Group Membership with PowerShell

A reader wants the benefits of dynamic Office 365 groups without having to pay for Azure AD premium licenses. It’s relatively straightforward to maintain the membership of a group with PowerShell.

Office 365 Groups Naming Policy Now Configurable in Azure Active Directory Portal

The Groups section of the Azure Active Directory portal now includes a preview of a feature to configure the Office 365 Groups naming policy without going near PowerShell. Although those proficient with scripts and GUIDs will lament this sad reduction in standards, the normal administrator will welcome the chance to forget some obscure syntax.

Office 365 Groups Naming Policy Now Generally Available

The Office 365 Groups Naming Policy is now generally available. The policy has taken nearly two years of preview to not get very far, but at least it’s now an official part of the service. Microsoft considers the naming policy to be an Azure Active Directory Premium feature. Many customers might think differently, especially because the naming policy must be implemented through PowerShell and can easily be mimicked through PowerShell. And of course, Exchange Online’s distribution list naming policy is free.

Tuning PowerShell for Office 365 Group Membership

A recent article prompted a check to see whether a PowerShell recommendation made sense and delivered better performance when executing a command to extract the membership of Office 365 Groups performance. As it turns out, the recommendation is valid, but whether you notice any difference is arguable.

Sending Protected Email to Teams, Yammer, Groups, and Shared Mailboxes

Block Guest Members from Microsoft 365 Groups and Teams

By default, the Groups policy for an Office 365 tenant allows group owners to add guest users to group membership. You can block this access if necessary, but it’s probably not what you want to do as blocking brings guest access to a complete halt across the tenant.

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.

Managing Office 365 Guest Users

How many guest users does your Office 365 tenant have? And how many of those accounts are actually used? Given that many Office 365 applications now generate guest user accounts to facilitate external access to content, managing these accounts is a growing concern.

How Microsoft IT Manages Office 365 Groups

Details of how Microsoft IT manages its deployment of Office 365 Groups were discussed at the recent Ignite 2018 conference. It’s a good idea to write down the basic framework of your Office 365 Groups deployment, if only to understand how all the different policies and features fit together.

Synchronizing AAD Security Groups with Microsoft 365 Groups

Security groups are often used to protect access to resources, but they can’t be used to control membership for Microsoft 365 Groups or Teams. If you want to use AAD security groups to control membership for Groups and Teams, you need to come up with a way to synchronize. PowerShell is available to do the job, and as it turns out, it’s not too difficult.
