With the Azure active directory powershell commandlets, we could control the lifecycle of office365 groups.Ideally when any office365 group is created for an action of creating a team in the backend it creates the azure ad group.With the Azure commandlets we have options to control the lifecycle of the office365 groups automatically.

Let’s say we ‘ve created Team for a partner project which completes in 1 year time period, we have got an option to expire this team in 1 year time during the team creation.This keeps the access reviews of the Microsoft Teams intact and ensures that only required persons have access to the company corporate data.

The default setting is unlimited days as it should be for most of the scenarios.

Firstly we need to connect to azuread module from the powershell. Since we do not have any group life cycle policy the value remains empty.

Microsoft Teams is being used as a most preferred method of communication platform by many organizations. By default in office 365 the group creation is enabled for end users which will allow them to create public and private groups. Few organizations are having the group creation disabled on the organization level for larger scale companies and have users request for creating the teams using a request form which will run through a automation process in the background with help of azure automation accounts ,Microsoft flow or few other mechanisms.

But few organizations are really interested in allowing the users to create the Office 365 groups once their workloads are migrated to office 365. This is primarily to increase the adoption rate of Office 365 workloads Microsoft Teams and SharePoint online.

We have more options available in Office 365 cloud app security. By leveraging these options we can better secure the Office 365 suite of products which in turn controls the Data loss prevention, security compliance, information governance and threat management for the entire organization.

Through Cloud App Security –

Navigate to Cloud App Security – https://portal.cloudappsecurity.com

Select and create Activity Policy

Do not choose any policy templates – select policy severity – category as per classification – Have selected compliance in below example.

When an office 365 group is created, we have options to collaborate with public partner accounts .As a result of this People outside organization can see and have access to office365 public groups contents when they are been invited as guests.

When we have allowed the end users to create the office 365 groups and invite the external partners to collaborate,over a period of time the groups left unattended without the access reviews. There is a high possibility of an user having access to the sensitive documents which they don’t need them anymore.

In order to alleviate these security issues , we can influence the Microsoft Azure Identity Governance – Access reviews

With the access reviews created for office365 groups , we can let the group owners review their office 365 public group guests present on them and take necessary action based on the requirement.

In order to create access review navigate to azure portal – Identity Governance – Access reviews – Click on access review – Select New access review.

Now we can create them with name ,description , start date and frequency of how often the access reviews needs to take place for the office365 groups.
