Microsoft Teams eDiscovery for Calling/Meetings

Customers have asked for it, and Microsoft has delivered! Microsoft just announced the launch of eDiscovery for calling/meetings. This latest update helps customers progress towards the Skype to Teams convergence roadmap. As a compliance admin whom are used to eDiscovery searches for Microsoft Teams messages and files, you will now be able to search and discover summary reports for every Microsoft Teams meeting or call within your tenant. In a nutshell, Teams supports eDiscovery for:

• Messages in Microsoft Teams (includes Skype for Business interoperability chats)
• Files in Microsoft Teams
• (NEW) Meetings/Calls in Microsoft Teams

Note: Support for Guest Users and Exchange on Premises users was recently added as well. For more details, please review this blogpost.

In this article I’ll give a brief overview of how the new eDiscovery for meetings/calls works as well as what exactly is covered under the meetings/calls category.

How does it work?

The process is as follows:

1. The services will collect information about every meeting and call in Teams.
2. This information is then used by the Call Record Processing services to generate a CDR (call detail record).
3. This CDR is then sent into a special folder located within the mailbox storage of all participants who dialed into the meeting/call.
4. The data is then indexed and made available to the eDiscovery functionality in the Office 365 Security and Compliance center.

So, when compliance admins search for Teams content (including users mailboxes in the scope of the search), call summaries for Microsoft Teams are going to be included in the output of the search.

What is covered in the meeting/call summary?

So, we now know that all calls and meetings within Teams are recorded in the summary, but what scenarios does this cover specifically? Well, with this recent launch the following scenarios are covered in the call/meeting summary.

• Meeting or call start and end time, and duration
• Call/Meeting join and leave events for each participant
  • VOIP join/calls
  • PSTN join/dial-in events
  • Anonymous join
  • Federated user join
  • Guest user join
• Calls to voicemail
• Missed or unanswered calls
• Call transfers (represented as 2 separate calls)

Note: When we talk about “meetings” this refers to scheduled meetings, channel meetups, ad hoc meetings, group chats turned into meetings with > 2 people. When we talk about “calls” this refers to one-to-one/P2P calls. 

Microsoft also has plans in the future to add support for other events such as:

• Screen and app sharing events in a meeting
• Recording events (with support for the cloud recording link and attaching the call/meeting recording transcript to the summary record in eDiscovery)
• Inclusion of meeting subject in the summary record
• Broadcast meetings
