From policy to Outlook in three steps
Assign users and teams
Link individual mailboxes or distribution lists to the right category list.
Let the service synchronize
The background service applies your policy to Outlook, OWA and supported mobile clients.
Built for administrators, invisible to users
No client deployment
Nothing needs to be installed in Outlook, so Office updates and roaming profiles do not disrupt the category policy.
Append or replace
Add managed categories to existing lists or enforce a complete approved list when governance requires it.
