Hello! Need help with expired Exchange Delegation Federation certificate. I've managed to renew the certificate following this MS sites:
We have hybrid environment where our on-prem users can't see our online users free/busy calendar information. This was because our Exchange Delegation Federation certificate expired. After we renew it the free/busy problem stayed. We figured that it might be the problem with Auth Configuration (get-authconfig |fl) for CurrentCertificateThumbprint value where this value is still from the previous Exchange Delegation Federation certificate.
Does anybody have experience with this? If we change this value to our new Exchange Delegation Federation certificate thumbprint is there any steps to do after changing that value? Some sites mention that we need to publish this certificate and also start HCW (this site: http://www.wave16.com/2018/06/test-oauthconnectivity-errormissing.html)
Will changing this Auth Configuration value for CurrentCertificateThumbprint to our new CurrentCertificateThumbprint have impact on our mail-flow or something else?
Is it possible to auto-renew this certificate?
