Restore-RecoverableItems

The EntryID parameter specifies the deleted item that you want to restore. The EntryID value for the deleted item is unique in the mailbox.

You can find the EntryID for specific items by using other search filters on the Get-RecoverableItems cmdlet (subject, date range, etc.).

The FilterEndTime specifies the end date/time of the date range. This parameter uses the LastModifiedTime value of the item.

Use the short date format that's defined in the Regional Options settings on the computer where you're running the command. For example, if the computer is configured to use the short date format MM/dd/yyyy, enter 09/01/2018 to specify September 1, 2018. You can enter the date only, or you can enter the date and time of day. If you enter the date and time of day, enclose the value in quotation marks ("), for example, "09/01/2018 5:00 PM".

The FilterItemType parameter filters the results by the specified MessageClass (ItemClass) property value of the deleted item. For example:

• IPM.Appointment (Meetings and appointments)
• IPM.Contact
• IPM.File
• IPM.Note
• IPM.Task

The FilterStartTime specifies the start date/time of the date range. This parameter uses the LastModifiedTime value of the item.

Use the short date format that's defined in the Regional Options settings on the computer where you're running the command. For example, if the computer is configured to use the short date format MM/dd/yyyy, enter 09/01/2018 to specify September 1, 2018. You can enter the date only, or you can enter the date and time of day. If you enter the date and time of day, enclose the value in quotation marks ("), for example, "09/01/2018 5:00 PM".

The Identity parameter specifies the mailbox that contains the deleted items that you want to restore. You can use any value that uniquely identifies the mailbox. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Domain\Username
• Email address
• GUID
• LegacyExchangeDN
• SamAccountName
• User ID or user principal name (UPN)

In Exchange Online, you can specify multiple mailboxes separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

The LastParentFolderID parameter specifies the FolderID value of the item before it was deleted. For example, 53B93149989CA54DBC9702AE619B9CCA000062CE9397.

This parameter is available only in the cloud-based service.

The MaxParallelSize parameter specifies the maximum number of mailboxes that are processed by the command in parallel. A valid value is an integer from 1 to 10. Typically, a higher value decreases the amount of time it takes to complete the command on multiple mailboxes.

The value of this parameter has no effect when the Identity parameter specifies only one mailbox.

This parameter is available only in the cloud-based service.

The NoOutput switch restores the deleted items directly without any command output in the console. You don't need to specify a value with this switch.

This parameter is available only in the cloud-based service.

The RestoreTargetFolder parameter specifies the top-level folder in which to restore data. If you don't specify this parameter, the command restores folders to the top of the folder structure in the target mailbox or archive. Content is merged under existing folders, and new folders are created if they don't already exist in the target folder structure.

This parameter is required for archives and optional for primary mailboxes. A destination folder will be created if it does not exist. Valid paths are:

• /
• /folder1
• /folder1/folder2
• folder1
• folder1/folder2

The preceding or trailing / will be ignored. Then, it will be treated as the relative path of the IPM sub-tree: /Top Of Information Store.

The ResultSize parameter specifies the maximum number of results to return. If you want to return all requests that match the query, use unlimited for the value of this parameter. The default value is 1000.

The SourceFolder parameter specifies where to search for deleted items in the mailbox. Valid values are:

• DeletedItems: The Deleted Items folder.
• RecoverableItems: The Recoverable Items\Deletions folder. This folder contains items that have been deleted from the Deleted Items folder (soft-deleted items).
• PurgedItems: The Recoverable Items\Purges folder. This folder contains items that have been purged from the Recoverable Items folder (hard-deleted items).

If you don't use this parameter, the command searches those three folders.

• DiscoveryHoldsItems (cloud-only): The Recoverable Items\DiscoveryHolds folder. This folder contains items that have been purged from the Recoverable Items folder (hard-deleted items) and are protected by a hold. To search for deleted items in this folder, use this parameter with the value DiscoveryHoldsItems.

The SubjectContains parameter filters the deleted items by the specified text value in the Subject field. If the value contains spaces, enclose the value in quotation marks (").
