How and when to decommission your on-premises Exchange servers in a hybrid deployment
I have a question. We want to decommission our one Exchange server but I see in the Microsoft tips that we should keep last one for administration. "If you don't have any on-premises mailbox(es)...
- So the reason why you'd want to keep at least one Exchange box is for management purposes, as mentioned above. Microsoft only supports managing Exchange related objects and attributes via the Exchange management tools, no way around it.

You haven't provided any details for your current and planned environment, so we cannot give you any guidance here. The article you quoted discusses all the details you need. Specific to management, if you plan to use AAD Connect/dirsync to centrally manage your users, keeping one Exchange box for management purposes is the only *supported* configuration. Doesn't mean thing won't work if you decide to remove the last Exchange box, but you'll be in unsupported configuration.
We have 2 on-premise AD DC which are sync via AAD Connect/dirsync to Office 365 Online. We have one old exchange server (which often falling down) so we decide to migrate via hybrid migration and now we disable this migration and stops connectors. But we are wondering if we can completely remove this server or what kind of administration we can the exchange server use in practice? Thx

- Hello,
