Why We Still Talk About Exchange 2010 Today?
As Microsoft Exchange Server 2010 stores user mailboxes in EDB database on the server, it helps a lot while managing and centralizing data. There are situations where administrators need mailbox data in Outlook PST format. Some other reasons include:
- Creating an offline backup of all the user mailboxes.
- Migrating mailboxes to another platform.
- Recovering mailbox data before server maintenance.
- Archiving inactive employee mailboxes.
- Meeting legal or compliance required.
- Opening mailbox data directly in Microsoft Outlook.
- Used when required to reduce the database size.
Since the PST file are portable and highly supported by Outlook, they are considered one of the most preferred mailbox storage formats.
Important Update about Exchange Server
Before exporting Exchange 2010 mailboxes, administrators should know that Microsoft support ended the extended support for Exchange Server 2010 on October 13, 2020. Talking about the recent update, Microsoft has also ended support for versions that are below 2016. It will no longer offer technical updates & services, bug fixes and guidance to the older and outdated versions. We recommend you to either use the latest and updated version of Exchange Server or else migrate to another platform.
Decoding the Export Process
This is a complex transactional database. A PST file, or Personal Storage Table, is a whole different animal. Microsoft Outlook uses a proprietary file format that contains copies of messages, calendar events and other items.
When you create an export Exchange 2010 mailbox to PST request, you are invoking the Mailbox Replication Service (MRS) by using PowerShell. Exchange 2010 Service Pack 1 brought a much more robust request-based architecture, unlike previous versions of Exchange that used a tool called ExMerge to do so (and was notoriously buggy and limited to 2GB files).
Issues, Challenges, and Errors
If you’ve ever attempted the export of an Exchange Server 2010 mailbox to PST, you know things don’t always go according to plan on the first try. Here are some of the technical obstacles lurking in the shadows.
1. The RBAC Permission Wall
In Exchange 2010, being a “Domain Admin” doesn’t give you the keys to the kingdom. Microsoft has role based access control (RBAC) in place and by default the “Mailbox Import Export” role is not assigned to any user, not even the administrator. This leads to the frustrating error message: “The term New-MailboxExportRequest is not recognized.” Many users think their install is broken because of this, when they just don’t have permission to the data..
2. UNC Path Required
You can’t export to a local drive, such as C:\PSTs, by using the New-MailboxExportRequest cmdlet. It requires a Universal Naming Convention (UNC) path like \\ServerName\ShareName\File.PST. Even if you specify the path, if the “Exchange Trusted Subsystem” group does not have explicit Read/Write permissions on that network share, the export will silently fail or will throw a cryptic MAPI exception.
3. Corruption of database and MAPI
Old databases suffer from “bit rot.” One corrupted email attachment and the whole export process can crash. You might get errors like MapiExceptionCallFailed or MapiExceptionNetworkError. But this is particularly hard when you try to export Exchange 2010 mailbox to PST format.
4. Large File Limitations
PST files can easily manage upto 50GB, Exchange 2010 starts to struggle once a mailbox exceeds its 20GB storage. Exporting might stall, or the resulting PST might become corrupted and unreadable by Outlook. Meanwhile, managing these “bloated” mailboxes requires additional parameters and a lot of patience.
Symptoms, Causes, and Their Technical Implications
Understanding the reasons behind a failure is the first step proceeding to fix it. Let’s look at the symptoms of a failing export and implementation to stop this failure.
| Symptom | Probable Cause | Implication |
|---|---|---|
| Export Status is “Queued” indefinitely. | The Mailbox Replication Service (MRS) is hung or overloaded with other requests. | Data migration delays; potential hardware resource exhaustion. |
| Error: “The destination path could not be found.” | Incorrect UNC path or missing permissions for Exchange Trusted Subsystem. | Total failure to initiate export and zero data movement. |
| Resulting PST is 0KB. | Database is dismounted or the mailbox is empty. | Misleading results and possible data loss if the source is not good enough. |
Quick Checklist for a Manual
Before you run your first PowerShell command to export Exchange 2010 Mailbox to PST, make sure your environment is set up. If you skip these steps it will almost surely throw an error.
- Verification: Verify Version Ensure your server is running Exchange 2010 Service Pack 1 or later.
- Account Permissions: Ensure that your admin account is a member of the “Organization Management” group.
- Network Share: Create a folder on a server with plenty of space. Share it and add “Full Control” for the “Exchange Trusted Subsystem” (ETS) group.
- Client Requirements: Do not install Outlook on the Exchange Server itself. May cause conflicts with the 64bit Exchange services.
- Space Audit: Make sure that the destination drive has at least 20% more space than the total size of the mailboxes you intend to export Exchange Server 2010 mailbox to PST.
Use PowerShell to Export it Manually
Below are some efficient steps to use PowerShell for this process:
- In the Exchange Management Shell, run the command:
New-ManagementRoleAssignment -Role "Mailbox Import Export" -User "Administrator"Now, close and re-open your PowerShell window and wait for the new command to appear after the session has been refreshed. - Try with only one user before you start with the bulk data conversion and make sure you have the permission to set it up correctly.
New-MailboxExportRequest -Mailbox "jdoe" -FilePath "\\Fileserver\PST_Backups\jdoe.PST" - After that, export all Exchange Server 2010 mailboxes to PST by looping through each and every mailbox existing in the database. Use snippet of the script:
$mailboxes = Get-Mailbox -ResultSize Unlimited; foreach ($mbx in $mailboxes) { New-MailboxExportRequest -Mailbox $mbx.Alias -FilePath "\\Fileserver\PST_Backups\$($mbx.Alias).PST" }
