Microsoft Teams Chat history keeps showing in search result in Outlook
The reason TeamsMessagesData folder would not have been moved is if there was any policy set that prevented items from being deleted. For example, a retention policy could have prevented deletions.
From my notes the only workarounds would be searching using "Current Mailbox" or "All Mailbox" scoped searches, or searching in the relevant module (Calendar, People, Tasks) for those items.
Follow the steps in the link below to exclude the specific Teams folder from the outlook search.
In the "Value: <folder name>" step, folder name will be written as "Teams Messages Data"
As the folder will be filtered as excluded, outlook will stop indexing hidden Teams messages during the search.
The folder name (Teams Messages Data) may vary depending on the software versions.
