Hi @Dalton Ramirez , how long has it been since you updated the information? It can take some time for the display name changes to propagate in Microsoft Teams. However, if the display name still doesn't update after a reasonable amount of time, you can try the following steps:
- Remove the guest user from the specific team in Microsoft Teams.
- Wait for a few minutes to ensure the removal is propagated.
- Re-add the guest user to the team.
This process should force Microsoft Teams to refresh the guest user's display name. Please let me know if this doesn't work.
Please let me know if you have any questions and I can help you further.
If this answer helps you please mark it as "Verified" so other users can reference it.
Thank you,
James
