Sharing access to Microsoft 365 items

Last changed:


Shared access is a technology that is used in various yasoon applications. It allows you to share Microsoft 365 entities like emails, conversations, chats or calendars with other Jira or Confluence users. You are basically giving them a very narrow access to certain information on your behalf.

Supported apps

Token sharing is currently only available for Atlassian Cloud products and will only work with Microsoft 365 (Office 365)

Token sharing is currently supported in the apps Outlook Email for Jira, Outlook Calendars for Confluence and Microsoft Teams for Jira.


Security is our top priority when sharing access to entities. Whenever a user shares something with other users, a permission entry, along with a reference to the users authentication tokens is stored in our encrypted database.

When a user requests access to a shared entity like an email, the request is validated based on the permissions configured. When this user is granted access, our server calls the corresponding Microsoft resource on behalf of the user that shared the item. As all the data handling is done via our servers, no direct access is granted to any un-privileged user.

Whenever the user that shared the entity logs out of the app, other users no longer have access to the shared resources. If the user renews their login, access to the shared entity will be restored.
