This month, Microsoft has started throttling email from outdated Exchange servers, Entra is taking control away from Active Directory, Microsoft and AWS are embracing multi-cloud, and Windows Search…
So this is, uh, especially, uh, relevant really for people that are still running Exchange Server on premises.
So from what I've understood, Exchange Server 2016 and 2019 are kind of both reaching end of life this October, and Microsoft is essentially saying that if you don't have the latest security baseline installed for those versions of the on-premises version of Exchange Server, if you're routing mail through Exchange Online, they're going to start throttling, uh, that, you know, uh, bandwidth, that route if you like.
And from what I can really understand from this, this is targeting organizations that are still running a hybrid, uh, you know, on premises and in the cloud kind of situation.
I, uh, you have to retain at least one on-premises Exchange Server if you want that kind of hybrid setup.
So you have the Exchange Server on premises to kind of deal with, uh, the management side of your on-premises estate, as it were.
But it looks like Microsoft is saying, "Mm, we're a little bit fed up with this.
We'd rather that you, uh, essentially came off these kind of legacy versions of Exchange Server." And they don't seem to be saying, you know, "We want you to, uh, get rid of your kind of on-premises, uh, Exchange management," but, you know, you can replace Exchange Server with the, uh, subscription edition [laughs] if you like.
Uh, but, you know, I don't know how many organizations are really doing that or what the situation with, uh, people migrating to that new version of Exchange Server actually is.
So what do you think is really going on here? Is that, you know, is it really kind of Microsoft just pushing people to subscription services essentially?
... and we look back, I don't know, say the last two years, there have been a ton of vulnerabilities are, in Exchange on-prem that have been exploited, um, and pretty badly, right, um, for organizations.
... we can support." Now, would Microsoft prefer all their customers to be fully online and in the cloud and no hybrid? Absolutely.
... we definitely are seeing that type of change, but I don't think it's l- Microsoft trying to really punish, um, users for, or organizations f- you know, for running on-prem.
They just want them to run, if they're gonna run with these on-prem, they have to be patched, and then they have-
