Asterofus Thanks for the link. That did the trick for me. I was not about to uninstall the security update. I just reinstalled exchange in March after we got hit by HAFNIUM 2 weeks before the patch came out.
I did not have to wait an hour, I restarted the Exchange Service Host and did an IISREST and ECP and OWA worked right away.
