Exchange administrators always need to be prepared against server crashes and data loss situations, though Exchange is far more secure because of Database Availability Groups(DAGs). There are different recovery methods by which administrators can recover a server even after crashes. Due to the integration with Active Directory, it is possible to rebuild the configuration of the Exchange from Active Directory. Also, many professional tools can be used to recover the lost Exchange data to different locations in different formats.
Active Directory is the place where all the Exchange Server settings are stored. So, it is possible to rebuild the configuration of the Exchange environment from Active Directory. Here is how you can do this:
To do this, you must be a member of Domain Admin, Enterprise Admin, or Account Operators. Use the following method to reset the computer account:
NOTE – It is essential to name the new server as the older one. Otherwise, it will not work correctly.
Note: Follow the same procedure for Exchange 2013 and 2010 also. For Exchange 2010, you need to run the following command –Setup /m:RecoverServer
The method mentioned above is used to retrieve a lost Exchange Server which is not a member of a Database Availability Group (DAG). There is a different method to recover a DAG member server:Read more
In simple language, Dial tone portability means allotting users a temporary mailbox for sending and receiving emails till their original mailbox becomes functional after a repair or restoration. This feature helps businesses to maintain email continuity in scenarios of Exchange Server failures or database issues.
You can have the temporary mailbox on the same server or another server in your organization (but they must contain databases with the same database schema version). The Autodiscover clients are automatically redirected to a new database (no manual update is required). When the original mailbox of the user has been restored, you, as an administrator, can merge the recovered mailbox and the dial tone mailbox.
In Dial Tone recovery, an empty database is created on a mailbox server, and the failed database is replaced with it. The empty database that you create is referred as dial tone database through which you can send or receive messages while your original database is being repaired.
The pre-requisites for executing the Dial Tone Recovery are:
Info: Exchange 2013/2016 Standard Edition supports up to five databases per server.Read more

Being an Exchange Server Administrator is challenging for a person as there are multiple threats which loom over the Exchange server environment all the time. Exchange database has all the user mailboxes of the organization, and that is why it becomes so vital to have a disaster recovery plan in case the Exchange Server faces any problem. Identifying the common threats and rectifying them is the core of a disaster recovery plan; it also includes the restoration of deleted or corrupt mailboxes.
Whenever an Exchange server faces a crash, the natural option of the Exchange Administrator is to retrieve the data from the backup. But backup may not be having the complete data always. Also, it may take too much time in making the mailboxes accessible again. That is why the first attempt should be to restore the mail flow.
Here are some exercises for Exchange Server 2019, 2016, 2013, & 2010 which we should follow in case of Exchange disaster so as to recover deleted mailboxes in full health:
Before committing changes to the database, they are written to the transaction log file which is a sequential set of logs. When all the logs are committed to a database, then the database is in a consistent state. Such a database is ready to get mounted on the Exchange Server. A database should be in a consistent state if you want to mount it on the server.
But when all the changes are not committed, the database is in an inconsistent state. Such a database cannot be mounted. So, if you are not able to mount a database, you should bring it back to a consistent state.
Most of the time, the Exchange server crashes due to a hardware failure like abrupt shutdowns, frequent power failures, hard drive corruption, or any physical damage to the physical components. So, the Exchange administrator should update the hardware routinely. Here are some common hardware components which can be changed periodically:
There are several settings which the Exchange server administrator can configure to stabilize the Exchange environment :
Running a mock drill of an Exchange server disaster will help you in earning some valuable inputs and make you prepare for an actual emergency. You can also get to know that whether your recovery methods are efficient enough to recover the data.
There are some inbuilt features in Exchange Server 2019, 2016, 2013, 2010 & other previous versions to repair a corrupt database. You can use these tools in case of severe issues.

There are generally two methods to recover archive mailboxes from Exchange 2010. The manual method involves using the New-MailboxRestoreRequest cmdlet. And then there is an alternative solution to recover archive mailboxes. Here, we will discuss both these methods in detail.
To use this procedure, first, you need to restore the database and logs from backup and use an alternative location to store the data. Now, follow the below steps to recover archive mailboxes in Exchange 2010.
New-MailboxDatabase -Recovery -Name <RDBName> -Server <ServerID> -EdbFilePath <RecoveryDBPath> -LogFolder <RecoveryLogsPath>
Eseutil /R Exx /l <RDBLogFilePath> /d <RDBPath>
Get-mailbox <UserID> | fl ArchiveGUID
New-MailboxRestoreRequest -SourceDatabase <RecoveryDB> -SourceStoreMailbox <ArchiveGUID> -TargetMailbox <UserID> -TargetIsArchive
TargetArchive ensure that recovery is performed against archive mailbox. Once the process is finished, the status will be changed to Completed.Read more
Even the latest Exchange Server versions like Exchange 2019 is not completely secure; data loss can happen due to manual errors like accidental deletion, EDB corruption, and access problems in Exchange Server. However, when a mailbox is deleted, it can be restored from Exchange 2019 database it is retained for some time. Because of the Exchange retention policy, mailbox which is deleted remains in the database till the expiry of the retention period (by default 30 days, which you can also set as per your needs). Once this period is over, the deleted mailbox will be removed permanently.
You can restore the Exchange 2019 mailbox using the Connect a mailbox option in Exchange Admin Center. You can connect the deleted mailbox to an existing user account (which is not associated with any other mailbox) or to a new user account. Then, you can connect the mailbox as follows:
The deleted mailbox gets connected to the user account. You can connect the disconnected mailboxes using the Management Shell cmdlet also. To do that, you can use these cmdlets:
Connect-Mailbox -Identity “mailbox name” -Database “Database name” -User “AD user account name” -Alias “Alias name”
Note: You can use the Get-User cmdlet to find the mailbox you want to connect.
However, these methods do not guarantee success if the Exchange database is corrupt or inaccessible. In that case, you need professional Exchange recovery tools. Kernel for Exchange Server efficiently recovers any kind of inaccessible Exchange data from corrupted Exchange databases and make it available for preview. Here, we have given the necessary steps for the recovery of lost Exchange 2019 mailboxes via Kernel for Exchange Server.Read more
