Exchange 2010 find empty distribution groups

  By Remigiusz Szatkowski | 28/09/2014 - 21:32 |

When we often create distribution groups, we forget about them.

Then we can have empty distribution groups in our Exchange Organization.

To find empty groups we can use Powershell.

First solution we can use EMS with below commands:

$DGs = Get-DistributionGroup -resultsize unlimited
$DGs | where-object {!(Get-DistributionGroupMember $_)}

As a result we receive list of empty distributions groups.

Second solution is to use PowerShell and Quest ActiveDirectory snapin like below:

Get-QADGroup -SizeLimit 0 -Empty $true -GroupType Distribution

Then we can get also empty distribution groups, but we can also modify this command to find security groups.

Few days ago Microsoft released CU5 for Microsoft Exchange Server 2013.

Probably most of you says: “CU 5 ??? Where is CU4 for Exchange 2013, did I miss something ?”

No you didn’t. Microsoft servicing strategy for Exchange 2013 says new CU for Microsoft Exchange 2013 every 3 months and sometimes service packs indicating a particular milestone in terms of features and support for Exchange Server 2013.

So now you see that Exchange Server 2013 Service Pack 1 is CU4 Exchange Server 2013. This is the same update for Exchange Server 2013.

You can check all updates CU, RU, Service Packs for Exchange Server releases in your website:

Exchange Updates

For Exchange Server 2013 we have:

  • Exchange Server 2013 RTM
  • Exchange Server 2013 CU1
  • Exchange Server 2013 CU2
  • Exchange Server 2013 CU3
  • Exchange Server 2013 CU4/Service Pack 1
  • Exchange Server 2013 CU5

Exchange 2013 SP1 not accepting emails

  By Remigiusz Szatkowski | 05/03/2014 - 14:03 |
Leave a comment

After installing SP1 for Microsoft Exchange 2013, you can expect some issues.

One of them is that after applying SP1 your Exchange server will stop accepting inbound emails and connections to port 25.

If you check Event Log, in Applications Log you will find entries with ID 7012 with source MSExchangeFrontEndTransport and with information:

“The service state for frontedn transport is inconsistent. Current state – Inactive. Expected state – Active.”

Using Powershell you can check state of this component:

Get-ServerComponentState servername01 -Component FrontendTransport

But you will see that this component is Active.

Also you can test inbound external email using Microsoft Remove Connectivity Analyzer, where you can find information about connection error to TCP port 25.

To resolve this issue you need to restart Microsoft Exchange Frontend Transport service.

You can do this using Powershell:

Restart-Service MSExchangeFrontendTransport

or just restart service in Services.msc.

When you do this, your server should now accept connections to port 25, and also you shouldn’t see warnings in Application Log.

Exchange 2010 assign rights to send to restricted distribution groups

  By Remigiusz Szatkowski | 24/02/2014 - 03:56 |
Leave a comment

In Microsoft Exchange we can set distribution group as restricted.
Then this distribution group will only accept messages from specified users.

We can set this settings in distribution group properties in tab Mail Flow Settings, Message Delivery Restrictions.

In section Accept messages from select Only senders in the following list and add all users who can send messages to this group.

Messages from other users will be rejected

DistributionGroupRestricted

 

If we have many of distribution groups with restrictions and we need to assign send rights to this groups then we have a problem.

Exchange 2010 message routing to public folders stuck

  By Remigiusz Szatkowski | 13/12/2013 - 01:48 |
Leave a comment

If you have two or more public folders databases in Exchange 2010 servers then you stosmailiprobably think that you have HA for public folders.

All of your public folders are replicated between those public folders databases and you think that when you will lost one server with PF database then you have another one and you wll have no problem with public folders.

If you think that then you are wrong !

In mailbox database you can specify public folder database for this mailbox database.

But if you shutdown one Exchange 2010 server with Public Folders database like your default server with PF’s then you will see that messages sent to mail enabled public folders stuck at the delivery queue on each Hub Transport server.
When you check this queue you will see that all of those messages are trying to get to public folder database on shutdown server, they are not redirected to available public folders database on another server.

So how to resolve this problem ?

First Microsoft recommend to install at least RU4 for Exchange 2010 SP2.
But this won’t help to resolve this problem.

You need to do something more.

In C:\Program Files\Microsoft\Exchange Server\V14\Bin directory find file:

EdgeTransport.exe.config

Edit it and manually add the following information to EdgeTransport.exe.config file:

<add key="SmartRoutingForPublicFoldersEnabled" value="True" />

Now save and restart Exchange Transport Service.

You need to do this on each Exchange 2010 Hub Transport server.

Now you will get fully redundant environment with Public Folders.

If one server with public folders database is missing then message are routed to another server with public folders database.

If this server will be missing for long time then remember to change default Public Folder database in mailbox database settings.
