Retention policies allow you to keep data that is needed to comply with your organization’s internal policies, industry regulations, or legal needs. If you have data that, if deleted, would be considered a liability, this is where having a retention policy would help. Retention policies ensure that your data is retained for a specified timeframe, regardless of what happens in the user app. Data can be retained and available for eDiscovery for 7 years, even if users delete their messages in Teams.

With retention policies for Teams, you can:

• Retain Teams chats and/or channel messages for a specified duration and then do nothing.
• Retain Teams chats and/or channel messages for a specified duration and then delete the data.
• Delete Teams chats and/or channel messages after a specified duration.
