Make sure you have the latest CU and Service Pack installed. As noted on top of the Article, you have to apply the Mitigations for September 2022 after the Install. Or check that the Exchange Server Emergency Mitigation Service applied the Mitigation correctly after the Installation.

Before installing i have checked the Mitigations on the Server

."C:\Program Files\Microsoft\Exchange Server\V15\scripts\Get-Mitigations.ps1"

The Exchange Mitigation Rule is still applied

."C:\Program Files\Microsoft\Exchange Server\V15\scripts\Get-Mitigations.ps1"
