Answer 1

Does the computer where this script is running has the ActiveDirectory module installed ?

Answer 2

Hello @Mahesh Jaiswal ,

Error clearly indicated that ActiveDirectory modules are not installed in powershell. Please go through the below link, install and try again

Answer 3

I think you have to specify the security protocol in your PS script.

Try adding this line

[System.Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Answer 4

I would say before calling your "sendmail" function in the main section

Answer 5

What is the .Net Framework version installed?
