How do I manage @mention suggestion in each space?

[Arisa Yamada]

Is there any function that the Account manager can set up different "@mention suggestion" in each space?

In the default setting, @mention suggestion will show when the user type "@" on Confluence. Is it possible to manage the suggestion name by account manager?

This function is important when there are different ongoing projects in each space by the different client in terms of security.

The @mention suggestions are pulled from the People Directory - if we could control access to that, we could meet your requirement to manage the suggestion list.

We haven't built into Confluence the ability to filter the People Directory (from which the at-mentions are pulled). We do have a request open to add more control: People Directory and "controlled" privacy / configure access to People Directory depending on Group membership. The ticket is still open if you are interested in commenting to emphasize your use case.
