Microsoft has recently deployed a new feature that automatically hides a new Microsoft Team from the Outlook Global address list and from the Groups section in Outlook (See Microsoft Message below).

In order to show the team in Outlook you need to use the new property in the Set-UnifiedGroup cmdlet called HideFromExchangeClients.

This command will show your Team in the Outlook Global address list and in the Group section in Outlook.

Set-UnifiedGroup -Identity “Your Team’s name” -HiddenFromExchangeClientsEnabled:$False

Note: there might be a delay before the Team is shown in Outlook.

If you only want to show the Team in the Outlook Global Address list and not in the Group section, you need to execute the following command instead.

Set-UnifiedGroup -Identity ” Your Team’s name ” -HiddenFromAddressListsEnabled:$False

It would be great if a there would be an option in the Team’s settings to hide or show the Team in Outlook, instead of having to use PowerShell, then the Team owner could change the behavior. If you like this idea you can vote for it in UserVoice :


Messagge that was sent to the Office 365 Message center :

Updated feature: Office 365 Groups created from Microsoft Teams will be hidden from Outlook by default

Based on your feedback, we’re improving how Office 365 Groups display across the Office 365 suite. New Office 365 Groups generated as a result of creating a team in Microsoft Teams will no longer show in Outlook by default.

This change will result in a more tailored experience in Outlook by removing groups which are predominately used in Microsoft Teams. For organizations that want to continue with the existing behavior of showing these groups in Outlook, an Exchange Online PowerShell cmdlet will be provided which can enable the group for the Outlook experience.

This message is associated with Office 365 Roadmap ID 26955.

How does this affect me?

When users create a new team in Microsoft Teams, the Office 365 Group associated with that team will no longer show in Outlook. The group will not be visible in the Outlook left hand navigation and will not be visible in the address book. Additionally, the group name will not resolve when attempting to resolve the address while authoring a new mail message in Outlook.

Groups created through Outlook and then later enabled for Teams will continue to show in both Outlook and Teams. Additionally, groups that were already created prior to this change will continue to display in both Outlook and Teams. This update will gradually roll out across Outlook and Teams in the coming months.

Groups created in Teams will continue to be visible in Teams, OneDrive, SharePoint Online home, Planner, and other groups experiences. This change affects visibility in Outlook, only.

We’ll be gradually rolling this out to Targeted Release customers starting late-April, and the roll out to the rest of the world will be completed by the end of August.
