Problem
Some users are not showing up when you try to @ mention them in comments or pages, either by name or username. Generally, most users are appearing fine this way, but one or more may not be appearing as expected.
Cause
- This is likely due to the content index with Confluence, and that user is just not in the present index.
- The user may not present under the People Directory tab and sometimes just a simple re-index may not solve the problem.
Resolution
Re-Index System
- Please follow the steps in How to Rebuild the Content Indexes From Scratch.
Select a sample user in the People Directory and manipulate the URL of the selected user:
https://your-confluence-url/confluence/display/~<selected-user>and change to
https://your-confluence-url/confluence/display/~<missing-user>in order to access the user who cannot be @ mentioned. After doing it the user should start showing up again and you will be able to @ mention the user.
See CONFSERVER-28615 - Getting issue details... STATUS for the associated bug
Re-Index Users
- Go to the <Confluence Address>/admin/force-upgrade.action URL
- Run 'UserIndexingUpgradeTask' task
this option does not exist in Confluence 8
Trigger User Info Indexing
If the above resolution did not help, you can do the following:
Go to the following URL
https://your-confluence-url/confluence/admin/users/edituser.action?username=user-to-mention- Modify or add any additional info about that user and save
- Confluence will attempt to index the user info which will show that user in the mention suggestions
