Hi All,
I have 3 CAS servers (EXCHANGE 2019 CU12) and F5 is built in front as connection load balancers.
I have confirmed we don't enable SSL Offloading in F5 and OUTLOOK anywhere disabled before upgrade to CU14.
Everything was smoothly when upgrade first server, and after upgrade the second CAS Server user call me said they can't login to OUTLOOK/OWA with the correct password.
I can't find any strange information in IIS or RpcHttp log, and just disable the EP for these two CU14 and stop the last one upgrade job.
After I disable the EP and user can login.
Is there any pals have the same issue like me or any suggestion for me to trouble shooting？
Thank you and have a nice day.
Update///Should I define NTLM Value to 3 as currently is no defined .
