Exchange 2010 remove disabled users from distribution group

  By Remigiusz Szatkowski | 08/02/2013 - 06:25 |

To keep Exchange Distribution Groups in order, we recommend to “clean” members of those groups.

We should remove all disabled users from distribution groups.

When we have a lot of Distribution Group we can use powershell script like below to do this.

This script gets all Distribution Groups from Exchange Organization, then will check every group for users which are disabled and they have Active Directory account in specified OU.

This script will also export all informations to a .csv file, where you can find following informations:

 

  • Name of distribution group
  • user DisplayName
  • SamAccountName
  • path in Active Directory to user account

Exchange 2010 SP2 after install RU4 message delivery is delayed on a BlackBerry mobile device

  By Remigiusz Szatkowski | 06/02/2013 - 06:30 | ,
Leave a comment

Microsoft has confirmed problems with message delivery to BlackBerry mobile devices after installation of Rollup 4 for Microsoft Exchange 2010 SP2.

This issue occurs only in specific Microsoft Exchange and BlackBerry Enterprise Server environment.

In this scenario:

  • You install Update Rollup 4 for Microsoft Exchange Server 2010 SP2 in an environment that is running against a Blackberry Enterprise Server (BES).
  • The BES uses MAPI or Collaborative Data Objects (CDO), instead of Exchange Web Services (EWS), to communicate with Exchange servers.
  • The mailbox contains many folders. For example, the mailbox contains more than 5000 folders.

You can encounter one or more of the following issues:

  • Email message delivery to the mailbox on a BlackBerry mobile device is delayed.
  • It takes a longer time to complete a folder hierarchy scan in the mailbox. For example, before Update Rollup 4 for Exchange Server 2010 SP2 was installed, a scan that typically takes 5 minutes may now take 30 minutes to 1 hour.
  • The Microsoft Exchange Information Store process (store.exe) on the Exchange Mailbox server may use excessive CPU resources.
  • Some BES event log entries are logged on the Exchange Mailbox server. Before Update Rollup 4 for Exchange Server 2010 SP2 was installed, these entries are less in occurrence or nonexistent.
  • Some events are logged in the BlackBerry Messaging Agent (MAGT) log. These events that are logged in the BlackBerry MAGT log resemble the “Busy Working” threads that are described in the following article in the BlackBerry Knowledge Base: Users may experience delayed email after upgrading to Microsoft Exchange 2010 SP2 Rollup 4 or Microsoft Exchange 2010 SP2 Rollup 5

 

Currentl there is no HotFix to resolve those problems. Probably Rollup 6 for Exchange 2010 SP2 will fix this.

But Microsoft recommend below workaround:

Method 1

Install Exchange Server Service Pack 2 RU 6 when it becomes available.

Method 2

Add more agents on the BES if they are not already at the max of 15 agents.

Method 3

Temporarily reduce the number of folders in the mailbox of the user.

Method 4

Move all users who have high folder counts (>500) to their own instances of BESAgent.exe.

Exchange 2010 how to control Mailbox Database Provisioning

  By Remigiusz Szatkowski | 04/02/2013 - 06:34 |

radar

With previous versions of Microsoft Exchange (2007 and 2003) when we created mailbox we had to specify mailbox database for this mailbox.

In Microsoft Exchange 2010 during mailbox creating we can let exchange to choose the database for new mailbox, or we have to select option that we want to select mailbox database.

This feature is called Automatic Mailbox Distribution – this feature allow Exchange to choose mailbox database for newly created mailbox if we don’t specify mailbox database.

By default in Microsoft Exchange 2010 all mailbox databases are enabled for provisioning, but we can disable them by setting mailbox database parameters IsExcludedFromProvisioning or IsSuspendedFromProvisioning.

IsExcludedFromProvisioning – we should use this setting to permanently exlude mailbox database from automatic mailbox distribution

IsSuspendedFromProvisioning - we should use this setting to temporarily exclude mailbox database from automatic mailbox distribution.

To check provisioning settings for mailbox databases we can use:

Get-MailboxDatabase | select name, *provisioning

ExchangeEnvironmentscript

Few days ago Steve Goodman published new version of Get-ExchangeEnvironmentReport.ps1 script on his Blog.

This script is really cool, and using it you can easly create report of your Mircosoft Exchange environment. 

 

New version supports Microsoft Exchange 2013 and fixes bugs reported by users.

We think that every Exchange administrator should has this script.

Executing the script is straightforward – the only setting you need is to specify where to write the HTML file:

.\Get-ExchangeEnvironmentReport  -HTMLReport c:\report.html

If you want it to email the results, the follow parameters are available to allow the report to be sent directly from the script:

.\Get-ExchangeEnvironmentReport  -HTMLReport c:\report.html -SendMail:$true -MailFrom:you@example.com -MailTo:you@example.com -MailServer:smtp.example.com

Exchange 2010 remove mobile device Error The ActiveSyncDevice Cannot be Found

  By Remigiusz Szatkowski | 30/01/2013 - 02:27 |
6 Comments

When you are trying to remove or wipe mobile device connected to mailbox, you can get error like below:

The ActiveSyncDevice Cannot be Found

You will get this error when you are trying to remove mobile device which were connected to user mailbox, and after user account was moved to other OU in Active Directory.

It’s caused because EMC can’t find “path” to old mobile device.

You can easly check this using two powershell commands:
Get-ActiveSyncDevice
Get-ActiveSyncDeviceStatistics
If you run CMDlet Get-ActiveSyncDeviceStatistics for some mailbox like below:

Get-ActiveSyncDeviceStatistics -mailbox JSmith | select DeviceId, Identity

you will get:

DeviceID                 Identity
--------                 --------
androidc1640524549       domain.local/Users/Test1/Smith John/.....
androidc2040902280       domain.local/Users/Test2/Smith John/.....

next try to run CMDlet Get-ActiveSyncDevice for the same mailbox:

Get-ActiveSyncDevice -Mailbox JSmith | select DeviceId, Identity

you will get:

DeviceID                 Identity
--------                 --------
androidc1640524549       domain.local/Users/Test2/Smith John/.....
androidc2040902280       domain.local/Users/Test2/Smith John/.....

Get-MessageTrackingLog how to speed up

  By Remigiusz Szatkowski | 28/01/2013 - 10:31 |
Leave a comment

Searching message tracking logs with cmdlet Get-MessageTrackingLog can take long time when you need to search few Hub Transport Servers.

Below command will search all transport logs on all Exchange Hub Transport servers and find only messages with subject “Important *”:

Get-TransportServer | Get-MessageTrackingLog -resultsize unlimited -start (get-date).adddays(-2) -end (get-date) -eventid Deliver | ? {$_.messagesubject -like "Important *"}

 

You can speed up this search by using remoting Powershell using CMDlet Invoke-Command.

You need to modify command like below and add Invoke-Command:

Get-TransportServer | Invoke-Command {Get-MessageTrackingLog -resultsize unlimited -start (get-date).adddays(-2) -end (get-date) -eventid Deliver | ? {$_.messagesubject -like "Important *"}}
