OWA and Exchange On-Prem (Hybrid)
I am having trouble getting solid answers for an Authpoint deployment.
The scenario, I have Hybrid Exch 2019 with most all mailboxes on-premise.
Wanted to look at Authpoint solution, however how do we cover exchange services on-prem. I was told we needed ADFS, but does this actually help us, if so how?
I believe I can use access portal, would ADFS negate the need to use access portal?
If access portal is used, what happens with activesync connections and Outlook Anywhere connections, I assume these are proxied also as all use port 443? In practice how does this work with the Access portal, how many times and when would MFA authentication be required? A mobile device for example, only one MFA when you initially set it up? I can see how it would work for OWA, but unsure for other services on the same port.
I know this puts some overhead also on the Watchguard so what happens if you have 100 activesync users, what effect would this have on an M370?
Thanks in advance
