INTRODUCTION
To improve performance, Groove uses a fan-out feature when you send a large message to several recipients who use the same Groove relay server.

For example, when you send 5 megabytes (MB) of data to ten members of a workspace, and when these members use the same relay server, the data may be sent to that relay server one time and then fanned out to the recipients from the relay server.



MORE INFORMATION
If you send lots of data to a workspace that has many other members, that data may be sent separately to each recipient, or it may be sent one time to each relay server. The Groove relay servers use the following factors to determine whether to fan out the data:
 * The number of recipients on each relay server
 * The volume of data that is to be transmitted
 * The transmission speed

Microsoft maintains multiple Groove relay servers. If your organization does not maintain its own relay servers, one relay server will be randomly assigned to your account when your account is created.

Your account will always use that relay server to receive data when the account cannot make a direct connection with the sender. Therefore, recipients in the same organization may not have the same relay server.
