The exact modified date for oab.xml is 6/7/2010 10.00am. Please advice how to modifed the script.

Hi, You need to change the command: $oabfile = get-item $oabpath"\oab.xml" This command just gets the folder 'b5dbeea9-2302-4d1a-8440-b9384a3e116b', not oab.xml. So the timestamp time you get is incorrect. to $oabfile = get-item "c:\Program Files\Microsoft\Exchange Server\ClientAccess\OAB\b5dbeea9-2302-4d1a-8440-b9384a3e116b\oab.xml" Then run the script again.

Hi, You need to change the command: $oabfile = get-item $oabpath"\oab.xml" This command just gets the folder 'b5dbeea9-2302-4d1a-8440-b9384a3e116b', not oab.xml.

Hi, First of all This line of script is quite right: $oabfile = get-item $oabpath"\oab.xml" You dont need to change it. It really retrieves the oab.xml file. The problem you are facing is due to this property $oabfile.lastaccesstime script is showing you "Last Access Time" of file, not the "Last modified time" of the OAB.xml. To get the last modified time of the OAB you can use "LastWriteTime" property of OAB.xml file. So in your script replace this $oabfile.lastaccesstime with this $oabfile.LastWriteTime everywhere and then you will get proper result. Hope this help you.

Hi, I tested this script in my lab and it shows the last access time of the folder "b5dbeea9-2302-4d1a-8440-b9384a3e116b"" not the OBA file. Laeeq, Have you tested this script? What's result? Thank you for your reply.

Here is the commands i ran: [PS] C:>$oabpath = "C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\OAB\0a76b67e-2db2-44f0-bb29-0fd8c36b7fe1" [PS] C:>$oabfile = get-item $oabpath"\oab.xml" [PS] C:>$oabfile Directory: C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\OAB\0a76b67e-2db2-44f0-bb29-0fd8c36b7fe1 Mode LastWriteTime Length Name ---- ------------- ------ ---- -a--- 7/7/2010 6:35 AM 21449 oab.xml You can see it shows oab.xml under the Name column, and also tells its directory.

Thank for your help. It is work now but i have another question, how to put send an email as CC:, In this script, they use $emailTo, can i use $emailCC?

Hi, You have really changed this script very much without considering what to pass and where to pass. Above mentioned error is self descriptive: New-Object : Exception calling ".ctor" with "4" argument(s): "The parameter 'from' cannot be an empty string.Parameter name: from And this line is causing that error $msg = new-object System.Net.Mail.MailMessage $emailFrom,$emailTo,$subject,$body Obviously error is correct as you are passing emtpy parameters to constructor of MailMessage object. There is no value in $emailFrom, and i think also in $emailTo etc. Replace these lines of code: ############Create a message object and initialize####################### $msg = new-object System.Net.Mail.MailMessage $emailFrom,$emailTo,$subject,$body ############ Edit the following fields ################################## #$msg.from.Add("postmaster@sapura.com.my") $msg.to.Add("sani@sapura.com.my") $msg.cc.Add("suriya@sapura.com.my") with This ############Create a message object and initialize####################### $emailFrom ="postmaster@sapura.com.my" $emailTo= "sani@sapura.com.my" $msg = new-object System.Net.Mail.MailMessage $emailFrom,$emailTo ############ Edit the following fields ################################## $msg.cc.Add("suriya@sapura.com.my") Also you have not assigned "body" to $msg object anywhere in your code. So in both if and else block you should add this line of code $msg.Body =$body before calling $smtp.Send($msg) Hope this help you.
