How to block Trello free trial in the Atlassian workspace?

[Love Lindqvist]

Hi, our company is shifting over to Jira and Jira Work Management.
But sometimes new users used to accidentally start Trello boards even if they dont have a Trello license.
How can I as the company admin block Trello visibility for unlicensed users?

Thank you

Hi Love! At this time, there isn’t a way for you, as an Atlassian admin of your organization, to prevent users from creating a Trello account or a Workspace or prevent them from subscribing to Trello.

However, there some alternatives you could try such as:

• Reaching out to the users who are currently using Trello, and ask them to delete their Workspaces and boards to ensure these users won't affect your Atlassian Guard billing costs. 
• Deactivate their Atlassian accounts preventing them from accessing Trello and any other Atlassian product.
• Block Trello's access by implementing some network rules on your firewall that will block users from access Trello. 

Here are some helpful resources you can share with your users when guiding them to leave and deleting their Workspaces and boards:

• Leave boards: https://support.atlassian.com/trello/docs/leaving-a-board-in-trello/
• Leave Workspace: https://support.atlassian.com/trello/docs/removing-people-from-a-workspace/#Removing-yourself-from-a-Workspace
• Delete Workspace: https://support.atlassian.com/trello/docs/deleting-a-workspace/
