One of the complicating factors in extending data retention policies to Teams is that Teams does not have its own single storage repository within Office 365. Instead, Teams creates many different data objects that are stored in several other services within Office 365.
This table (taken from Microsoft article: "Location of data in Microsoft Teams") shows how Teams data is stored in different repositories depending on the content type.
Unlike legacy archiving tools that can only capture and archive some of the Teams conversation and content, Archive360 for Microsoft Teams compliantly captures, archives and manages every part of a Teams conversation.
Archive your Microsoft Teams content and meet your regulatory, legal and privacy requirements.
