This Script has been Written to fullfil one of the App Team request, Here is the requirement:
- For any user if Primary SMTP address changes, a notification to be sent to them.
- Alert notification should include the Previous & Changed value.
- Format should be CSV.
They require it as they need to update the details in the Application if Primary SMTP address alters.
Here is the powershell magic 🙂
Extract the Zip file from below link
Update the .ps1 file variables:
$limit = (Get-Date).AddDays(-60) #for report recycling
$email1 = “VikasS@labtest.com”
$from = “EmailAddressChange@labtest.com”
$smtpserver = “smtpserver”
Note: Script is using CustomAttribute11 & matching it to $regex = ‘^\d+$’ (integer) i.e. all mailboxes that have employeeid.
This can be changed as per your organization.
First time when the script is run it creates a State-Email.csv file, this is the state file and on next run it compares the newly fetched data with the previous state file to capture the changes which it sends to the specified email in .csv format.
Transcript will be stored in Logs folder & report will be kept inside Report , these will get recycled every 60 days.
Create a schedule Task to run it daily or as per your requirements.(Note: don’t forget to fill start in field when scheduling the batch file)
Note: Script has been tested with Exchange 2010 but should work with other versions as well, just change the shell parameter.
Exchange management Shell is a requirement for this script.
