How to Use Microsoft 365 Priority Accounts for Access Checks

Microsoft 365 priority accounts are a way to mark accounts for special processing. Microsoft is building features to exploit priority accounts, but they can be used for other purposes, like checking if an account has account to a resource. Of course, multiple other methods exist to do the same job, but that’s not reason to exclude priority accounts from the mix.

Hitting the Million Messages Limit in an Aggregate Group Mailbox

A curious problem happened when a mailbox reported hitting a folder item limit (one million items). The mailbox was an aggregate group mailbox, a system mailbox used to make it easier to search Microsoft 365 Groups. Microsoft now uses a different method to search group mailboxes and will remove these arbitration mailboxes by the end of 2021. If you meet the problem, use a mail flow rule to stop messages being delivered to the mailbox.

Change in Guest Access for Teams: No Effect on Tenants Already Using Teams

Microsoft is changing the default setting for guest access to Teams from Off to On.

This post offers some ideas about using policies to control guests and how to check what these accounts are used for.

Outlook’s Groups Menu Bar Now Includes Teams

Outlook for Windows has a Groups menu bar which is displayed when conversations in a Microsoft 365 group are accessed.

Millions of Microsoft 365 Groups Fail Auto-Renewal Annually

Among some interesting statistics offered at the Ignite 2020 conference, we learned that 79% of Microsoft 365 groups successfully auto-renewed because of their activity. That leaves 21% of groups which didn’t meet the bar to be automatically renewed. Only groups within the scope of an expiration policy are included, but even so millions of groups weren’t renewed. Is that a problem?

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!

How to Archive Microsoft 365 Groups and Teams with PowerShell

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.

Updates for Groups Management in Microsoft 365 Admin Center

The Groups section of the Microsoft 365 admin center has been overhauled recently and several useful changes were made. Restore deleted groups is the headline act, but the other updates also deliver value. Collectively, they make Groups easier to manage.

How to Find Guests in Microsoft 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.

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.

How to Post Information to Microsoft 365 Groups or Teams Channels

It’s easy to create a webhook connector to post information to a team channel or an Microsoft 365 group. What might not be quite so easy is formatting the JSON payload. Here’s how to use a template card to simplify the process.

Teams Now Supports Dynamic Microsoft 365 Groups

The latest version of the Teams desktop and browser clients support the creation of dynamic teams based on dynamic Office 365 Groups. The functionality is welcome, as long as you can pay for it as every member who comes within the scope of a query used for a dynamic team needs an Azure AD P1 license.
