What you are seeing is expected if your account is a member of any elevated groups. The recommendation is to not add any mailbox enabled account to an elevated group and permission inheritance wont be disabled.
User account security inheritance being disabled automatically
Hi everyone. Hope I am asking in the right place.
I have Exchange 2019 on a 2012R2 domain. I was experiencing issues connecting remotely to Exchange. According to multiple articles, the solution was to enable permissions inheritance on the AD user account (ADUC -> Open user -> Security -> Advanced -> Enable Inheritance).
This works fine, but it appears that this setting is being reverted regularly and frequently. As in every few hours.
Something in Active Directory really doesn't like permissions inheritance, but it appears to be required for Exchange to run.
Thanks in advance for any thoughts.
