The Outgoing tab in Bridge shows a log of the content that you have shared to other projects. You can check on the status of shared content and view details about what was shared. Project administrators can also archive entries in the Outgoing tab to hide them from project members.
You can also share various types of content with other projects right from the Bridge tool. See Share Files and Folders with Another Project from Bridge and Share Sheets with Another Project from Bridge for more information.
You can also share various content from the tools themselves and those actions will be logged in the Outgoing tab. This includes:
In the Outgoing tab of the Bridge tool, there is a table with entries for each time content was shared out of your project.

Title: This value can come from:
The title entered when the items were shared. If none was entered, the title is "untitled".
If a file or sheet is shared through an automation, the corresponding file or sheet name appears as the title.
The RFI number and title
If items from this project are imported into another Autodesk Forma project, the title will be Imported.
Type:
Status: Sent, In review, Accepted, Rejected, Expired, Partially failed, or Failed
Sent: When sheets are shared with a link, this indicates that the sheets were sent to the recipients.
In review, Accepted, Rejected, or Expired: When shared files must be accepted by a project administrator, this is the status of that process.
Partially failed: Multiple items were shared at one time. One or more files or folders failed to share, but other items were successful. Learn more about troubleshooting Bridge failures.
Failed: The content was not successfully copied to the target project. Try again.
Reviewed by: The project administrator who accepted or rejected the content
Shared to: The project the content was sent to
Shared by: The member who sent the content
Shared on: The date the content was shared
Automatic syncing enabled: Yes or No. This indicates whether an automation was enabled when the original content was shared.
You can view further details about what was shared by selecting an instance.

This will take you to a view of what items were sent and details about the event, including title, message, who it was shared to, and more. If the content was shared through an automation, there will be a section that shows which automation it was shared through and you can navigate to the folder directly from there if you have access.
