since april 2023 searching in outlook 2021 does not bring up recent emails in search results

since april 2023 searching in outlook 2021 does not bring up recent emails in search results.

i guess that the search function inside outlook 2021 is provided by windows.

i have windows 11 pro french 22H2 22621.1635

i have office 2021 64 bits 2304 16327.20214.

i tried the following without any success :

done all windows and office updates.

in admin : DISM.exe /Online /Cleanup-image /Restorehealth

in admin : sfc /scannow

rebuild indexation.

indexation troobleshooter.

in admin : dism /Online /Disable-Feature /FeatureName:"SearchEngine-Client-Package" + reboot

in admin : dism /Online /Enable-Feature /FeatureName:"SearchEngine-Client-Package" + reboot

in admin : Get-AppxPackage -Name Microsoft.Windows.Cortana | foreach {Add-AppxPackage -register "$($_.InstallLocation)\appxmanifest.xml" -DisableDevelopmentMode} + reboot

take ownership of C:\ProgramData\Microsoft\Search\Data\

what else to do because i dont want to do a clean install of windows and all my apps and settings ?

does it have anything to do with office and not windows ?
