Reactions that are added after the query returned the message, will not be archived. because there is a known bug in the Export API confirmed by Microsoft.

Initially, the membership information is determined based on periodic membership queries and/or message sender information (there is a chance that this is not 100% accurate all the time. VFC data is only as accurate as the information returned in the periodic query).

From the time a conversation is being recorded, accurate participant information can be determined from join/leave system events.

Initially, the membership information is determined based on periodic membership queries and/or message sender information (there is a chance that this is not 100% accurate all the time. VFC data is only as accurate as the information returned in the periodic query).Microsoft has a feature on the roadmap to include , which provide the list of members at the time of the query. From the time a conversation is being recorded, accurate participant information can be determined by combining the initial membership information received from the periodic membership queries and from join/leave system events in the exported messages which can resolve this issue in the future.

Participant join and leave times are stored as follows:

. Join/leave system events provide historical information and are used to verify changes in participant membership since the last membership information update.

Note: Until the data from the initial membership query is received, only partial participant information is available, determined from the system events and user activity. The receipt of accurate participation information can also be delayed due to the delay in the ingestion of Teams chat and channel messages, and any throttling limits that exist for the API.

Supported for both chats and channels with limitations, participant information is not 100% accurate all the time (see below)

Chat: supported

Channel: supported, but the API only offers team based queries (user based queries are not available, teams have to be configured as recorded extensions)

Chat and channel membership information is collected at the point when the Export API is queried. The accuracy of the chat and channel membership information has no effect on the selective capture, there will be no data loss. However, due to the periodic query nature, the membership information might not be accurately reflected in the database for the chat and channel conversations. See Participant Join/Leave Events for more information.

Supported

Available through regular polling and system events.

The Webhook/DLP API is a set of Microsoft Graph APIs which that allow subscribing to change notification events for both chat and channel messages in a Teams tenant. The Webhook API based integration provides a real-time capture of messages and attachments.

For more information, see https://docs.microsoft.com/en-us/graph/teams-changenotifications-chatmessage

The system utilizes other Graph APIs to collect additional information such as attachments, user information, group membership, etc.

The Export API is a set of Microsoft Graph APIs which allow querying both chat and channel messages for specific users and teams in a Teams tenant. The Export API based integration provides a non real-time capture of messages and attachments.

For more information, see https://docs.microsoft.com/en-us/microsoftteams/export-teams-content

The system utilizes other Graph APIs to collect additional information such as attachments, user information, group membership, etc.

Supported by automatic allocation of archived users and teams to file queues

Note: Recording Director and Media Recorder roles are always co-located for Export API based deployments

Supported by deploying standby servers

Note: Recording Director and Media Recorder roles are always co-located for Export API based deployments

Scales by adding more servers

Note: Recording Director and Media Recorder roles are always co-located for Export API based deployments

• Microsoft only retries sending events a few times, so data can be lost after that. The risk can be mitigated by deploying multiple Recording Directors behind a load balancer.
• Data loss is possible if selective archiving is configured and the participant information is not up-to-date (see Participant Information for more information).

No data loss since the queries can be executed at any time. Microsoft stores messages for the defined retention period (see https://docs.microsoft.com/en-us/microsoftteams/retention-policies). Deleted messages are kept for 21 days only.

Supported

Supported

Chat: data duplication, messages and files are multiplicated based on the number of archived users in the chat

Channel: no duplication, messages and files are stored only once even where there are multiple archived users in the same channel

SMTP-based export only

User/participant-based or conversation/chat based export

SMTP based export only

User/participant based only

The following limitations should be considered when deploying the Export API based solution:

• The Microsoft Export API only returns the latest version of the message, not the complete history of the message, previous edits will not be returned.
• The onBehalfOf attribute is missing for apps, such as Forms, the sender is not recognized due to this limitation.
• Microsoft has no official SLA for the completeness of the records, we estimate min. 15 minutes, but it is recommended to use the default 1 hour delay for the queries.
• Participant join/leave times are not accurate (see above)
• Reactions that are added after the query returned the message, will not be archived. because there is a known bug in the Export API confirmed by Microsoft (see above)
• Private and  shared channel messages are not supported (change is planned for 9.8.1)
