![]() To create a mailbox restore request using PowerShell, we have to use the display name, legacy distinguished name (DN), or mailbox GUID of the deleted mailbox. To connect to a deleted mailbox we can also use the Exchange Management Shell. When we have chosen the mailbox we want to restore, we click on the Icon and follow up the last steps. If we need to recover (or reconnect) a deleted mailbox, we go to our Exchange Admin Center (EAC) and browse to recipients > mailboxes > … > Connect a mailboxĪ new window opens and we can select the server in which the deleted mailbox is located: At the end of the mailbox retention period, the mailbox is permanently deleted from the database. Deleting a mailbox does not mean that it is permanently deleted from the information store database right away, only that it is flagged for deletion. If we delete a mailbox, it is disconnected for a default period of 30 days (the mailbox retention period), and we can reconnect it at any point during that time. Recovery of deleted mailboxĮxchange server gives us the opportunity by default to be able to recover “deleted” mailboxes with board tools. Of course, this is a theoretical view on the configuration - active mailboxes can be moved around the servers for several reasons, but the principal configuration stays. However, on the second Exchange we have its own active database and on the third and fourth a passive copy, the lagged copy is on the first Exchange, etc. On the fourth Exchange Server we have the lagged copy of it. If we take now a closer look on MDB1, which is the active mailbox database from our first Exchange Server, there is a passive copy of it on the second and third Exchange Server in our environment. If we have a closer look at how the mailbox databases will be distributed, the picture could look like this: This is a “building block” according to the definition from Microsoft. However, in our example, we are running an environment with four Exchange Servers. To visualize this bit more, let us have a look on this example:įirst, we define our databases in three categories, displayed in the legend below: One of this copy is a lagged copy and we can use this to restore the database to a specific point in time during the ReplayLagTime. However, from each mailbox database we are running on our Exchange environment, Exchange is configured to have multiple copies of each mailbox database. ![]() ![]() Database copiesĭepending on the size of our on-premises Exchange environment, we have multiple mailbox databases running in at least one DAG. Note: It is important to set up an identical server regarding OS & ServicePack level. Now we join the new server to the right Active Directory domain with the same server name and we install the Exchange Server role requirements.Īfter performing the required server reboot, we start an elevated command prompt and change to the folder containing the Exchange ISO and run the command below: setup /mode:recoverserver /IAcceptExchangeServerLicenseTerms We go to our Active Directory and we reset the old computer account. However, that means we perform the recovery using the /mode:RecoverServer during the installation. The Setup.exe /Mode:RecoverServer command uses that information during the installation of Exchange on a new server with the same name. Note: I highly recommend that you use the same hardware components as the server you are replacing.Īs I have already mentioned, the Exchange Server settings are stored in Active Directory. If we run, for example, a physical Exchange Server that has crashed and we need to recover it, we can simply install a new Windows Server instance with the same naming convention and service pack level. If we need to recover an Exchange Server, Microsoft has created an option for us so we can recover Exchange Servers without using SystemState / OS Backup. In previous versions of Exchange, DSAccess provided directory lookup services for components such as SMTP, message transfer agent (MTA), and the Exchange store.Įxchange added new attributes to the Active Directory domain service scheme and made other modifications to existing classes and attributes. Since Exchange 2013, all access to Active Directory is done by using the Active Directory driver itself. However, Microsoft made some changes to how Exchange works with Active Directory.Īctive Directory is the core Microsoft Exchange component that allows Exchange services to create, modify, delete, and query for Active Directory Domain Services (ADDS) data. Exchange is fully integrated into Active DirectoryĮxchange Server (2013–2019) uses Active Directory to store and share directory information with Windows. Let me explain to you why this is not needed anymore. I have been asked numerous times if we need to back up an Exchange environment and if yes, how do we do it? Well, the answer is simple… No, there is no need to backup Exchange anymore! This is a simple answer, but the reason is more complex.
