Exchange hosting. What is it made from?

Question

Microsoft Exchange

Hello

Knowledgeable people, please tell me how ms exchange mail services are provided?
Is it possible to make an analogue of Microsoft services?

In principle, I am able to install an exchange server, a normal one, I had some experience with versions 2003, 2010 and 2019. Do I understand correctly that exchange does not have a real multi-tenant? Those. I can't make a hosting exchange server where there will be several domains? I don't mean Internet addresses, but AD. After all, you can't make several users with the name "Georgy Goshin" in different AD domains (subdomains, organizations, I'm bad at Windows), or is it possible? After all, if a client buys a service from MS, when he creates his users, he is not limited in the choice of user names and does not see anyone else from the same server? Is it possible to do something like this for yourself? How are exchange hosting services provided?

Answer 1

If you are ready to compete with Microsoft, then you can try. If you need to budget. In general, those who do not want to give themselves to Microsoft, but want Exchange, start Exchange on-premises. For those who want to fool themselves, they go to Cloud differently.

Those. I can't make a hosting exchange server where there will be several domains? I don't mean Internet addresses, but AD. After all, you can't make several users with the name "Georgy Goshin" in different AD domains (subdomains, organizations, I'm bad at Windows), or is it possible?

Can be on-prem. But a very expensive solution. In the Cloud, this works, where users with the name "Georgy Goshin" have completely different SMTP your_address.onmicrosoft.com and the tenants are isolated at the Azure level.

Answer 2

Do I understand correctly that Exchange on-premises is an Exchange server installed "at home" on its own hardware? (there are some hosting control panels for it, but they do not change the essence, they only manage the creation and editing of users).
What is Cloud and how can domains be separated at the Azure level if Exchange authorizes users in AD, and AD does not allow [email protected] and [email protected] to be made? Tell me, where can I read something about it?
Of course, no one will compete with MS, especially since they made it impossible with their SPLA rates, but there are some clients for whom hosting in MS is not suitable, and the ease of use provided by the MS Exchange server is suitable.
