$pause = Read-Host “Hit enter to exit script…” ☺

I could never learn a foreign language in school so maybe the two are related. If you asked that because of the $blnIsValid variable, that was some input from a friend (who does have a lot of VB experience) helping me structure the do/while statements. I just didn't bother to change the variable name. With that said, I do feel like I'm picking Powershell a little bit easier each day. Thanks for the suggestions on simplifying, that does look a lot cleaner. The script will typically be run from a shared drive so it's easier for the analyst to right-click and run with powershell. The 10 second delays were added just to allow the person executing the script a chance to see the results before the script exits since that results in the session closing.

I would simplify a bit… Take ### Prompt for Server Name ### [Console]::ForegroundColor = "cyan" $Hostname = Read-Host 'Enter servername to be added to the SMTP Relay List' [Console]::ResetColor() And become ### Prompt for Server Name ### Write-Host 'Enter servername to be added to the SMTP Relay List' –ForeGroundColor Cyan -NoNewLine $Hostname = Read-Host Take [Console]::ForegroundColor = "yellow" Write-Host "No Hostname entered..." [Console]::ResetColor() And become Write-Host "No Hostname entered..." –ForeGroundColor Yelloow This just makes the code (much) easier to read. Also, I really don’t understand the point behind the “delay 10 seconds” prior to exiting the script.

I created the script because we were having continous issues with applications needing the ability to relay email not being configured on our specified receive connectors. We have 6 servers split between two sites (each hosting MB, HT, CAS roles), with one server in each site being designated the relay server. We use SRM in our environment to failover/migrate virtual machines between our sites. With that process VMs are configured with new IP addresses when moved to the alternate site, so we've run into issues where a VM has been failed over but the "failover IP address" hasn't been added to the receive connector for relay. Although applications only target one server in each site for relay, we keep the connector configurations updated on all of the Exchange servers just in case one has to stand in for that purpose. So I wanted to create an easy way for our less experienced admins to take a request for relay access and ensure all of the relevant information was gathered and configured on all of the receive connectors. So with all of that said, here's the script I came up with. I decided to not to pursue functionality outside of the EMS since most of the Analysts responsible for this task will have the EMS installed. ### Load Exchange Shell ### .
