7. Security & Compliance
 Microsoft Teams is Tier C compliant at launch. This includes: ISO 27001, ISO
27018, EUMC, SSAE16, SOC1 Type I and II, SOC2 Type I and II, HIPAA,
FERPA, and GLBA, and EU Model Clause (EUMC)
 Enforces team-wide and tenant-wide two-factor authentication, single sign
on through Active Directory, and encryption of data in transit and at rest.
Files and notes are stored in SharePoint and OneNote, respectively, which are
backed by SharePoint and OneNote respective encryption.
 Data in Microsoft Teams lives in the data center region where the tenant
is created/located. Data is not housed in the United States unless the tenant
itself is provisioned in the US. In future, Microsoft Teams will provide GoLocal
support, where data remains in country (not just in region). Updates will be
shared in the public Office 365 Roadmap.

the existing site, mailbox, and notebook are used
in place.
 For each new team, a single channel named
General is also created, along with the associated
SharePoint folder and OneNote notebook
section.

services as Planner, Power BI, Team Services, etc.

will not be able to configure connectors, but can still receive messages from connectors configured by other users.
The following table gives more specific information, for users with Exchange hosted in other environments:

11. Microsoft Teams Content Lifecycle
11
Content Lifecycle Value
What happens when a member of
a team is removed?
All data remains and all existing users can continue to use the team. If the removed
user was the only owner of the team, an IT admin can retake control of the team by going
through the Office 365 admin center and adding themselves or someone else as the team
owner.
Data retention and data deletion
policy
Microsoft Teams retains all messages. Microsoft Teams retains deleted messages for at
least 7 days, and at most 30 days, before messages are permanently deleted. There is no
support yet for retaining edit and deletion logs for all messages.
Information protection in
Microsoft Teams
SharePoint and OneNote security measures apply to all documents shared and all notes
saved in Microsoft Teams. For chat, Microsoft is building the roadmap for various
information-protection measures such as archive, eDiscovery, legal hold, audit history,
content search, custom retention policies, and Customer Lockbox. Updates on these and
other features will be shared in the public Office 365 Roadmap.
Can I edit or delete chat messages
that I sent?
You can edit or delete your chat messages during the first 24 hours after they are posted
