Export Mailbox From Dismounted Exchange Database Using Best Method

Need to Dismount Exchange Database and Export Mailbox

There are times when it has required to dismount database. The reasons can be when you
replace hardware/software component
- Create offline backup
- Fix sever related issue
These are the various situations when you required to dismount the database.

“I have a dismounted Data Base on Exchange Server 2010 SP1 server and now I cannot get the Database Mounted again. I Installed new Exchange Server as:
2 HUB/CAS Server
2 mailbox Server
so I am facing problem in moving the Mailboxes from the dismounted Database to new server”

How to Mount Exchange Database on Server

You can mount your exchange mailbox database on server with the help of two methods by
1. Using PowerShell Command
2. Using exchange admin centre

#1. PowerShell command to mount Exchange Database on Server

To mount the Database on the Server that has mailbox server role installed on it you can use “Mount Database” cmdlet.

Mount-Database-identity [-AcceptDataLoss][-Confirm[]][-DomainController][-Force][-WhatIf[]]

This command can only be used when the following conditions are satisfied
1. Exchange IS service is running
2. Exchange Replication service is running

#2. Using Exchange Admin Center

To manage Exchange 2013 database you can use this GUI medium. What you need to do is first login to exchange Admin Center (EAC) for which you would be required internal and external URL. Check by running the New-EcpVirtualDirectory command in Exchange Management Shell

Get-ECPVirtualDirectory |Format-List Name, Internal|URL,ExternalURL

1. Once you login to EAC, click on “Servers” in the feature pane and click on “Databases” tab
2. Now select the database that want to be mounted on Server and then click on “More” button in the toolbar.
3. Click on “Mount” option and wait for a while to let the application mount the database.

You can use any of the following methods to mount the database on the server. However there are times that error “unable to mount database” can restrict smooth mounting. In such situations you can adopt a solution and convert your mailbox from Exchange to Outlook and then try to mount them on server.

Advantage of Using the Export Request:-

The PST file can be shared or saved on the shared network from where it can be accessed by the exchange server.
There is a provision to extract the mailboxes into PST file and access the mailboxes simultaneously at times.


When you are exporting mailbox it must be less than 50 Gb in size. Because the maximum PST file size limit that Outlook supports is 50 GB. And if the file size is large in size then multiple PST files can be created for every folder in a mailbox.

Common Reason To Move Mailbox to PST

- For Compliance Purpose.
- For creating Point-In time snapshot
- For creating an archive of the Mailbox

Tech Talks

1. The database is dismount and I just have 17 GB free

Ans. If the database is dismounting on its own and you have 17GB free space, then I would like to recommend you to create a new mailbox database on a separate set of disks and move the users there.

2. My database is dismounted and I am getting alerts regarding that. What to do?

Ans. What you can do is take a backup of the database and keep the backup or you can export the mailbox in database as PST file.

3. I have third party program, the program reads the EDB file and export the information but when I scanned the dismounted database, the email server stop sending and receiving.

Ans. As already discussed, use an Exchange aware backup platform to back up your database. And then use the third party tool along with the backup software to export any information.


Export Mailbox from Dismounted Exchange Database blog is aimed to help users when they dismount database and trying to mount it back. And How they can use the PowerShell command to mount the database. Scenarios where database is dismounted and need to export mailboxes to PST then surely a third party application should be adopted.

Note-> The EDB to PST Converter software can run without Exchange Server Environment.
