Summary: NewMailboxRepairRequest, also known as the successor of the IsInteg tool, is a PowerShell cmdlet to repair or fix issues with a specific mailbox or all mailboxes in an Exchange Server database (.edb) file. In this article, you will learn how to use the NewMailboxRepairRequest cmdlet to repair mailboxes and resolve issues, such as missing mail items, outdated mailboxes, inaccessible mail folders, etc. We also shared an EDB converter tool to help you quickly and safely move the mailboxes from the faulty database to a new database to resolve issues with the mailboxes.
In your Exchange organization, users accessing their email accounts via Outlook may encounter issues with the mailbox at any time. For example, this may happen due to problems with the Exchange mailbox, database, or server.
In such cases, administrators are required to repair the mailbox and fix issues that users are encountering. These issues may include but are not limited to the following:
If the users are experiencing these issues with their mailbox, you may need to repair the user mailboxes using NewMailboxRepairRequest PowerShell cmdlet in Exchange Management Shell (EMS). It can also be used to fix database errors and resolve mailbox-related issues.
Before we head into the repair side of things, there are a few things you need to take into consideration when repairing specific or multiple mailboxes using the NewMailboxRepairRequest cmdlet.
To avoid disruption, you may use Exchange recovery software, such as Stellar Repair for Exchange. It lets you repair the database and extract all the mailboxes to PST files with complete integrity. You can also export the mailboxes recovered from the faulty database to a new healthy database copy on your Exchange Server directly using the software. With the help of the software, you can save time and fix problems related to the Exchange database and mailboxes in a few clicks.
With the New-MailboxRepairRequest cmdlet, you can use the following parameters for mailbox or database repair:
To run the command New-MailboxRepairRequest, assign the permission and roles required by executing the following cmdlets in the EMS.
Once the required roles and permissions are assigned, you may refer to the few examples of commands below to run the New-MailboxRepairRequest cmdlets against a user’s mailboxes or mailbox database:
New-MailboxRepairRequest -Mailbox User1 -CorruptionType ProvisionedFolder,SearchFolder -DetectOnly
The above command only detects the issues. It does not repair the problems found in the mailbox or database. To run a repair against a mailbox, you can run the following command in the Exchange Management Shell (EMS):
New-MailboxRepairRequest -Mailbox User@domain.com -CorruptionType FolderView
The above command goes and detects and repairs all folder views for the mailbox listed above, email@example.com
New-MailboxRepairRequest -Mailbox User1 -CorruptionType ProvisionedFolder,SearchFolder,AggregateCounts,Folderview -Archive
The above command detects and repairs all corruption types for User1’s mailbox, including their Archive.
New-MailboxRepairRequest -Database DB01 -CorruptionType AggregateCounts
The above command detects and repairs AggregateCounts for all mailboxes on mailbox database DB01.
You may also combine all the parameters to repair all corruption types. The command is as follows:
New-MailboxRepairRequest –Mailbox firstname.lastname@example.org –CorruptionType SearchFolder, AggregateCounts, ProvisionedFolder, FolderView
Similarly, you can check and repair the mailbox database using the New-MailboxRepairRequest cmdlet.
New-MailboxRepairRequest –Database “MBXDB01” –CorruptionType ProvisionedFolder –DetectOnly
Although New-MailboxRepairRequest is a handy cmdlet that allows you to fix issues with Exchange mailboxes and databases without dismounting the database, it is important to highlight that the cmdlet is available in Exchange Server 2010 SP1 and later versions only. Also, it may not repair a dismounted database or mailbox stored in a dismounted database. For such cases, you need to use the EseUtil utility or Exchange recovery software, such as Stellar Repair for Exchange. It supports all Exchange versions, including Exchange Server 5.5 to Exchange Server 2019.
It can fix large, severely corrupt, or damaged Exchange databases, recover mailboxes and save them as individual PSTs. You may also export the recovered mailboxes directly to Office 365 or Live Exchange Server.
