[<CommonParameters>]Description
The Restore-Mailbox cmdlet copies end-user data from any server running Microsoft Exchange Server 2010 to a mailbox on an Exchange 2010 Mailbox server in the same organization that has adequate space and resources to support the mailbox. The Restore-Mailbox cmdlet can only use disconnected mailboxes on a server as a source of data, and the cmdlet can only use connected mailboxes as a target for data.
You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
Examples
Example 1
Restore-Mailbox -Identity Scott -RecoveryDatabase MyRecoveryDatabaseThis example restores a mailbox for user Scott from the database MyRecoveryDatabase.
Example 2
Restore-Mailbox -Identity Scott -RecoveryDatabase MyRecoveryDatabase -RecoveryMailbox John -TargetFolder RecoveryThis example restores John's mailbox content into Scott's mailbox under the Recovery folder.
Example 3
Restore-Mailbox -Identity Scott -RecoveryDatabase MyRecoveryDatabase -SubjectKeywords "Meeting" -ContentKeywords "business" -IncludeFolders \Inbox,\CalendarThis example restores only the mail with the subject Meeting, with the message body containing the word business, and with the message location either in the Inbox or Calendar folder. This example assumes that the mailbox is in English.
Example 4
Get-Mailbox -Database MyDatabase | Restore-Mailbox -RecoveryDatabase MyRecoveryDatabaseThis example bulk restores all the mailboxes in the MyDatabase mailbox database that are also present in MyRecoveryDatabase.
Parameters
-AllContentKeywords
The AllContentKeywords parameter specifies the filters for all of the following:
- Subject
- Message body
- Attachment content
This allows an OR search of all these fields. If your search criteria are part of the subject, message body, or attachment content, you get results.
| Type: | String[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010 |
-AllowDuplicates
The AllowDuplicates switch copies mail items without checking if they're duplicates of existing items and without removing duplicate items. You don't need to specify a value with this switch.
We recommend that you use this switch with the IncludeFolders parameter.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010 |
-AttachmentFilenames
The AttachmentFilenames parameter specifies the filter for the attachment file name. You can use wildcard characters in the string. For example, you can use *.txt to export items that have a .txt extension.
| Type: | String[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010 |
-BadItemLimit
The BadItemLimit parameter specifies the number of corrupted items in a mailbox to skip before the export operation fails.
| Type: | Int32 |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010 |
-Confirm
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax:
-Confirm:$false. - Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.
| Type: | SwitchParameter |
| Aliases: | cf |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |

-EndDate
The EndDate parameter specifies the end date for filtering content that will be exported from the source mailbox. Only items in the mailbox whose date is prior to the end date are exported. When you enter a specific date, use the short date format defined in the Regional Options settings configured on the local computer. For example, if your computer is configured to use the short date format MM/dd/yyyy, enter 03/01/2010 to specify March 1, 2010.
| Type: | DateTime |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |

| Applies to: | Exchange Server 2010 |
-ExcludeFolders
The ExcludeFolders parameter specifies the list of folders to exclude during the export. Folders are excluded as they're entered. They aren't localized. For example, excluding calendar only excludes calendar in English because calendar in other languages is a different word.

(For example, the value specified with the Identity parameter isn't the same as the value specified with the RecoveryMailbox parameter.) In this case, the Restore-Mailbox command performs a merge. If the values are the same, the TargetFolder parameter isn't required.

| Required: | True |
| Accept pipeline input: | False |
