Logon to Office 365 via command line without prompting for credentials

You can store the password securely in a file and load it when you are running the script, without prompts. Check for example here: https://powertoe.wordpress.com/2011/06/05/storing-passwords-to-disk-in-powershell-with-machine-based-encryption/

Thanks for your response. Am I executing this wrong?

Hi, thanks for your reply. Step 1 asked for your credentials. Is there any way we can extract this information from a text file so that you do not need to input them?

You do realize you have to STORE those credentials to the text file first? This is what steps 1 and 2 do.

You do not need to include those steps in the script file. But you need to run them at least once on each machine you will be running the script from.

Hi, on the final step, as soon as I run;

Connect-MSOLService -Credential $cred

Select allOpen in new window

I am prompted for a username and password?
 
I completed the other steps successfully.

You arent using the step to READ the stored credentials, the path you have given is wrong or the variable names don't match.

My bad! All good!

Awesome!
