Using Invoke-MgUnarchiveTeam in Graph PowerShell

In this article, we will cover the Invoke-MgUnarchiveTeam cmdlet, which is designed to unarchive Microsoft Teams. Archiving teams is a common practice for preserving past projects, but sometimes these teams need to be restored for active use. This cmdlet allows administrators to bring archived teams back into action.

Cmdlet Syntax

Invoke-MgUnarchiveTeam -TeamId <String> [-BodyParameter <Hashtable>] 

TeamId: The required parameter representing the ID of the archived team to unarchive.

Usage Examples

Example 1: Unarchiving a Single Team

Invoke-MgUnarchiveTeam -TeamId "5b6d987a-42f2-4b13-b9e7-46db673b1a3f"

This command restores the archived team with the ID 5b6d987a-42f2-4b13-b9e7-46db673b1a3f to its active state, making it available for all team members again.

Example 2: Unarchiving Multiple Teams

$teams = @("team-id-1", "team-id-2", "team-id-3")
foreach ($team in $teams) {
    Invoke-MgUnarchiveTeam -TeamId $team
}

This script unarchives multiple teams, ensuring that all specified teams are restored to an active state.

Example 3: Bulk Unarchiving Teams Using a CSV File

For larger environments where you need to unarchive multiple teams at once, you can use a CSV file. The CSV should have a column header called TeamId that lists the IDs of the teams you want to unarchive. Example CSV content (teams.csv):

TeamId
5b6d987a-42f2-4b13-b9e7-46db673b1a3f
7c9e214d-6b58-4b13-b2f6-3e9c878a34a5
11fcd582-7a46-4bb5-8a3a-b2a6db789b68

PowerShell script for bulk unarchiving:

$teams = Import-Csv -Path "C:\Path\to\teams.csv"
foreach ($team in $teams) {
    Invoke-MgUnarchiveTeam -TeamId $team.TeamId
}

This script reads the TeamId column from the CSV and unarchives each team listed.

Cmdlet Tips

• Valid Team IDs: Ensure the TeamId provided is valid. If the team has never been archived or does not exist, the cmdlet will not work.
• Permissions: The user running the cmdlet must have sufficient permissions (e.g., Microsoft Teams administrator) to unarchive teams.
• Bulk Operations: When unarchiving multiple teams, consider the load on the system. For large volumes of teams, perform the unarchiving in batches to avoid throttling issues.

Possible Errors & Solutions

Error	Cause	Solution
Team Not Found	Invalid TeamId or team does not exist.	Verify the TeamId is correct and the team exists.
Insufficient Permissions	User lacks sufficient privileges.	Ensure that the user has the necessary admin role in Teams.
Invalid Request - Team is Already Active	The team is already active, not archived.	Double-check the team’s archive status before running the cmdlet.
Throttling Issue - Rate Limiting Applied	Too many requests in a short period.	Reduce the frequency of requests or use batching.

Use Cases

• Reactivating Project Teams: Sometimes project-based teams are archived after the project ends. However, new developments may require the same team to be active again. This cmdlet simplifies the process of unarchiving such teams, allowing members to continue collaborating.
• Seasonal Teams: Teams created for specific events (e.g., conferences, training, or campaigns) are often archived after the event. Unarchiving these teams allows for easy reactivation when the event is repeated the next year, saving administrators from creating a new team from scratch.
• Audit and Compliance Reviews: Teams may be archived after audits, but regulatory requirements might require reactivating these teams for additional reviews or inquiries. The Invoke-MgUnarchiveTeam cmdlet allows compliance officers to restore access to these teams without recreating them.

Conclusion

The Invoke-MgUnarchiveTeam cmdlet is an essential tool for any Microsoft 365 administrator tasked with managing archived Teams. By providing the ability to unarchive individual or multiple Teams, administrators can maintain an efficient workflow and restore collaboration tools as needed. Whether you're reactivating project teams, seasonal groups, or compliance-related teams, this cmdlet ensures that archived data can be quickly accessed and used again.

Using bulk unarchiving via CSV adds another layer of efficiency, especially for larger organizations. With the right permissions and the correct use of Team IDs, this cmdlet provides a seamless way to bring archived Teams back into the active roster.
