Exchange 2010 SP2 RU3 move mailbox speed up

  By Remigiusz Szatkowski | 19/12/2012 - 11:14 |

If you are using RU3 for Microsoft Exchange 2010 SP2 you can have issue with mailbox move.
When you move mailboxes between databases you will have an issue with long time to finish move mailbox. It’s caused by some sort of cleanup tasks which have to be finish before move mailbox is marked as completed.

When you have RU3 this “cleanup task” is repeated for 5 times every 30 seconds for each mailbox. This is caused by RU3 which change parameter maxCleanupRetries and set it for 5.

To resolve this issue you have to uninstall RU3 or change parameter maxCleanupRetries.

So on every CAS Exchange Server you need to open folder:

C:\Program Files\Microsoft\Exchange Server\V14\Bin\

find file MSExchangeMailboxReplication.exe.config

edit and find parameter maxCleanupRetries

Next you need to change value from 5 to 1.

When you save this file after modification you need to restart  MSExchangeMailboxReplication Service

In Exchange 2010 environment with many Active Directory Sites we have to provide access for clients connecting from multiple sites to our Exchange Server.

When our Exchange and Active Directory environment is spreads across country or world, we often use AD Sites. Then we have to make sure that every AD Site is supported by ours Exchange CAS servers Autodiscovery.

So we need to add AD Sites to AutoDiscoverySitesScope in our Exchange CAS Server.

First we should check existing configuration of CAS servers. To do this we can write below command:

Get-ClientAccessServer | fl Name, AutoDiscoverSiteScope

 

We will get list of all Exchange CAS with AutoDiscoverSiteScope.

If we don’t know what AD Sites are in our environment we can get list of AD Sites using:

Get-AdSite

When we want to add AD Site to Exchange CAS we need to use Set-ClientAccessServer CMDlet like below:

Set-ClientAccessServer -identity MXCAS01 -AutoDiscoverSiteScope "Location Site 1, Location Site 2"

While you are using Search-Mailbox to find, delete or to copy items from mailbox you can use Advanced Query Syntax parameter to define what kind of items you are looking for.

To export mailboxes from specified mailbox database use:

ForEach ($mbx in (Get-Mailbox -Database DatabaseName)) {

Service Pack 1 for Exchange 2010 changed mailboxes import export to .pst file.

After you install Service Pack 1 for Exchange Server 2010 you need to use new CMDlet’s to import or export mailboxes:

  • New-MailboxExportRequest - to export mailbox
  • New-MailboxImportRequest - to import mailbox

To be able to export or import mailbox you need to meet following requirements:

  • have Export Import RBAC rights
  • have network share where you will export mailbox to .pst file

 

Assigning needed rights to export import mailbox from Exchange 2010:

When you write New-MailboxExportRequest in EMS (Exchange Management Console) and you will receive error that this command is not recognized, it means you don’t have adequate permissions.

You have to add Mailbox Import Export role for specified user or security group.

This security group should be universal.

Below command will add necessary permissions for security group MBX_imp_exp:

New-ManagementRoleAssignment -Name "Import Export Mailbox Admins" -SecurityGroup "MBX_imp_exp" -Role "Mailbox Import Export"

Sometimes we need to find when user logged to mailbox for the last time.

To achieve this we need to use  Get-MailboxStatistics CMDlet

Below command will display LastLogonTime for mailbox JSmith:

Get-MailboxStatistics JSmith | select DisplayName, LastLogonTime

 

If we are using shared mailboxes we also should display user account which were used to log to mailbox.
This command will display mailbox name, LastLogonTime and user account used to logon:

Get-MailboxStatistics JSmith | select DisplayName, LastLogonTime, LastLoggedOnUserAccount

 

When we want to get logon time information for all mailboxes in database or in mailbox server MX01, we need to use Get-Mailbox CMDlet, and pipe result to Get-MailboxStatistics
