• one or more non-transitory computer-readable media storing instructions that, when executed by the one or more processors, cause the system to perform operations comprising:
• receiving a message to be posted to a group-based communication system, wherein a plurality of users are permissioned to access content associated with the group-based communication system;

• generating, based at least in part on the message and the interaction data and by the group-based communication system, a second characteristic associated with a second user profile of a second user of the plurality of users, wherein the second characteristic is associated with a second organizational identifier associated with a second organization that is different from the first organization;
• determining that the second organization is external to the first organization;
• determining, based at least in part on the second organization being external to the first organization and by the group-based communication system, a first presentation characteristic of the message associated with the first characteristic and a second presentation characteristic of the message associated with the second characteristic;
• causing the message to be displayed in accordance with the first presentation characteristic via a first instance of a user interface presented via a first client of the first user;
• and
• causing the message to be displayed in accordance with the second presentation characteristic via a second instance of the user interface via a second client of the second user.
