Using Outlook for iOS for personal email and calendar management
No. The available Outlook mobile calendar setting in the provided documentation is Hide Declined Events, not a setting to hide tentative events or invitations that have not been accepted.
On Outlook for iOS or Android, the documented path is: Settings > Calendar > Hide Declined Events
If the goal is to hide invitations that are still tentative, no supported Outlook for iPhone setting for that is documented here.
