We're currently using Barracuda Cloud as our Spam filter and have an on-prem exchange. We're planning on moving to Exchange Online and got a great quote from our MSP that made sense to us instead of continuing to do on-prem Exchange. They're now like "oh... we forgot to quote you the Barracuda Total Email Protection" Cha-Ching!
Here's what we want to know...
Is it possible to have mail flow through Barracuda Cloud (just spam filtering) and go on-prem for archiving and then have the mail flow back out to our Exchange Online? Basically the archiving being a middle man proxy. I think Barracuda Total Email Protection is a great service/product, but for what we're trying to do here and what we currently have on-prem it's overkill.
Thanks!
