As an IT administrator, managing Microsoft 365 Groups can be a crucial task to ensure your organization’s collaboration and communication channels are properly set up and secured. This comprehensive guide will walk you through various PowerShell cmdlets and techniques to effectively manage your Microsoft 365 Groups.

When users create or edit a group in Outlook, you can provide them with a link to your organization’s usage guidelines. This can be helpful if you have specific requirements, such as a preferred prefix or suffix for group names. To do this, you can use the Microsoft Graph PowerShell to define the usage guideline hyperlink.

Start by checking out the Microsoft Entra cmdlets for configuring group settings and follow the steps in the Create settings at the directory level. After running the Microsoft Entra cmdlet, users will see the link to your guidelines when they create or edit a group in Outlook.

If you want to enable your Microsoft 365 groups with Send As permissions, you can use the Add-RecipientPermission and Get-RecipientPermission cmdlets. This will allow Microsoft 365 group users to send and reply to email as the group, directly from Outlook or Outlook on the web.

$groupAlias = "<GroupAlias>"
$userAlias = "<UserAlias>"
$groupsRecipientDetails = Get-Recipient -RecipientTypeDetails GroupMailbox -Identity $groupAlias
Add-RecipientPermission -Identity $groupsRecipientDetails.Name -Trustee $userAlias -AccessRights SendAs

Create Classifications for Microsoft 365 Groups

You can create sensitivity labels that users in your organization can set when they create a Microsoft 365 Group. This is recommended over the previous groups classification feature.

If you still want to use the previous groups classification feature, you can create classifications that users can set when creating a Microsoft 365 Group, such as Standard, Secret, and Top Secret. Use Microsoft Graph PowerShell to define the classification for Microsoft 365 Groups, as shown in the following examples:

$setting["ClassificationList"] = "Low Impact, Medium Impact, High Impact"
