Filed under: General — telnet25 @ 5:45 pm


If your company has requirement adding different attributes on user at  GAL, such as employee number, IPhone or blackberry filed into user properties in GAL, here is supper easy and safe way to get the work done.

In this scenario the management is looking to see additional field for all users within the GAL

  • Emp. number
  • IPhone
  • Black Berry

As you can see we do not have any of these files in out the box configuration on GAL


Open MMC from Exchange server ( you need correct permissions to achieve the desired goal) see the link for permissions if you are interested in granular permissions.

Log into your Exchange Server

Click Start , in the search type “MMC”

hit enter


Click on “Details Templates Editor


Here is full Video

Now you will see these filed within the outlook



To delete what you have done is pretty simple open MMC Console and click on “restore”

Exchange 2010 Performance Counters

Filed under: General — telnet25 @ 4:50 pm

When you have performance related issues and concerns that are the basic things to look for in exchange 2010?

Possible causes of poor performance ,

Performance issues may raise when mail server is sized wrong and unable to satisfy the current load, the basic counters, Memory, CPU, Disk averaged read write. The typical indication of poor performance , outlook popup indicates retrieval data from problem.ExcahngeServer.local etc..

What to look for?

Isolate if the issues is specific to one client or effecting more then one user.

Understand and investigate your CAS Servers , “CAS ARRAY”, remember when MAPI ( Outlook) client opens up MAPI request to connect to it’s own mailbox the, MAPI request will not directly go to Mail Box servers, it will go to your CAS server and CAS will talk to MBX server ( MAPI) behalf of requester.

Use your tool box and set of tools in there in E210. the most common one is Performance Troubleshooter.


I want to talk about MSExchangeIS\RPC Averaged Latency and the changes in the counter recommended thresholds.

in Exchange 2003 and 2007

MSExchangeIS\RPC Averaged Latency < 10ms

The value has changed as the business logic

MSExchangeIS\RPC Averaged Latency < 250ms

The new model in E210 Client MAPI request shown as below. The MAPI client ( Outlook) who want to connect to it’s mailbox database has to fallow below logic.

Outlook Client ( MAPI Users)———(MAPI)————> CAS ———-(MAPI)———–MBX Server

MBX————–(MAPI)————->CAS———-(MAPI)———->Outlook Client ( MAPI Users)

  • Averaged Latency should be less than 250ms at all times……
  • The generally-accepted warning threshold for MSExchangeIS\RPC Requests is less than 70 at all times…..


What would be considered as bottleneck ?

  • Although store.exe has 500 threads in Exchange Server 2007 / 2010, consuming more than 70 at one time is evidence of a bottleneck.
