Exchange 2010 Mailbox PST export – New-MailboxExportRequest

Remember the Export-Mailbox command on exchange 2007??? The main problem I personally had was the annoying outlook requirement. 
With the exchange server 2010 service pack 1 release, M$ introduced a new Cmdlet to export mailboxes on the server. And it does not require outlook.

Step 01 – Mailbox Import Export Role Assignment
Grant the user account permissions to export mailboxes (By default no account has the privileges to export mailboxes)
New-ManagementRoleAssignment -Role “Mailbox Import Export” -User administrator

Step 02 – Setup the Export File Location
We need a network share to export files. (Eg – \Exch01PST_export)
The Cmdlet gives an error if you point to a directory directly on the Hardisk (Eg – F:PST_export)
Create a Shared folder on a serverNAS and grant Exchange Trusted Subsystem user account read/write permissions to the folder
Exporting Mailbox Items with “New-MailboxExportRequest”

Supporting Cmdlets that can be used with MailboxExportRequest
Start the process of exporting a mailbox or personal archive to a .pst file. You can create more than one export request per mailbox. Each request must have a unique name.
Change export request options after the request is created or recover from a failed request.
Suspend an export request any time after the request is created but before the request reaches the status of Completed.
Resume an export request that’s suspended or failed.
Remove fully or partially completed export requests. Completed export requests aren’t automatically cleared. You must use this cmdlet to remove them.
View general information about an export request.
View detailed information about an export request.
In this example
Shared folder name-  PST_export
server name- EXCH01
Share Path –  \Exch01PST_export
Mailbox – amy.webber

Folder permissions – 

For this example we are going to use New-MailboxExportRequest cmdlet with the following parameters :

-baditemlimit 200 -AcceptLargeDataLoss
The AcceptLargeDataLoss parameter specifies that a large amount of data loss is acceptable if the BadItemLimit is set to 51 or higher. Items are considered corrupted if the item can’t be read from the source database or can’t be written to the target database. Corrupted items won’t be available in the destination mailbox or .pst file.
The BadItemLimit parameter specifies the number of bad items to skip if the request encounters corruption in the mailbox. Use 0 to not skip bad items. The valid input range for this parameter is from 0 through 2147483647. The default value is 0.
Exporting the Whole Mailbox
Run the following Cmdlet to initiate the mailbox move request:  New-MailboxExportRequest
New-MailboxExportRequest -baditemlimit 200 -AcceptLargeDataLoss -Mailbox amy.webber -FilePath \Exch01PST_exportamy.webber.pst

Exporting the User’s Online Archive
If you want to export the user’s online archive to .pst, use the –IsArchive parameter.

New-MailboxExportRequest -baditemlimit 200 -AcceptLargeDataLoss -Mailbox amy.webber  -IsArchive -FilePath \Exch01PST_exportamy.webber-Archive.pst

Exporting a Specific Folder
You can export a folder from the users mailbox using the -IncludeFolders parameter
Eg: inbox folder layout-
To export the inbox folder
New-MailboxExportRequest -baditemlimit 200 -AcceptLargeDataLoss -Mailbox amy.webber -IncludeFolders #Inbox# -FilePath \Exch01PST_exportamy.webber.pst
Checking the Progress of the Mailbox Export Request

To check the current statues of the mailbox export request use the following cmdlet:
Get-MailboxExportRequest | Get-MailboxExportRequestStatistics
People do crazy stuff scripting with this Cmdlet. Look around in the interwebs for some scripts.

Managing calendar permissions in Exchange Server 2010

Admin may get asked to set and add / Edit permissions for shared Calendars.
these Sharing options are not available in EMC, so we have to use exchange power shell on the server to manipulate them.
View existing Calendar permissions
Get-MailboxFolderPermission -identity "Networking Calendar:Calendar"
There are 4 MailboxFolderPermission cmdlets in Exchange Server 2010:
Each cmdlet have different syntax, follow the links for more information..
In this scenario we need to set following permissions to the Calendar Resource named “Networking Calendar.

user – “Nyckie” – full permissions

all users – permissions to add events without the delete permission

  • To assign calendar permissions to new users  “Add-MailboxFolderPermission”
Add-MailboxFolderPermission -Identity "Networking Calendar:Calendar" -User [email protected] -AccessRights Owner
  • To Change existing calendar permissions  “set-MailboxFolderPermission”
set-MailboxFolderPermission -Identity "Networking Calendar:Calendar" -User default -AccessRights NonEditingAuthor
This assigns the owner righs to the user “nyckig” for the calendar of the “Networking Calendar” resource.and sets NonEditingAuthor permissions as the default permission for the calendar for all other users
Here are the other permission levels you can assign:-
None – FolderVisible
Owner – CreateItems, ReadItems, CreateSubfolders, FolderOwner, FolderContact, FolderVisible, EditOwnedItems, EditAllItems, DeleteOwnedItems, DeleteAllItems
PublishingEditor – CreateItems, ReadItems, CreateSubfolders, FolderVisible, EditOwnedItems, EditAllItems, DeleteOwnedItems, DeleteAllItems
Editor – CreateItems, ReadItems, FolderVisible, EditOwnedItems, EditAllItems, DeleteOwnedItems, DeleteAllItems
PublishingAuthor – CreateItems, ReadItems, CreateSubfolders, FolderVisible, EditOwnedItems, DeleteOwnedItems
Author – CreateItems, ReadItems, FolderVisible, EditOwnedItems, DeleteOwnedItems NonEditingAuthor – CreateItems, ReadItems, FolderVisible
Reviewer – ReadItems, FolderVisible
Contributor – CreateItems, FolderVisible
The following roles apply specifically to calendar folders:
AvailabilityOnly – View only availability data

LimitedDetails – View availability data with subject and location

source –
