Hi Arjun,
Please follow below steps for MS Outlook Email VBO:
1. Create copy of Send Email Action As Save Email
2. Rename Send Item Code bock - Save Email (or any new name)
3. Add Parameter as Input for save Location of msg file
Open code block and comment and as per below:
'mail.Save

mail.SaveAs("File location to save.msg /Parameter as input")
Working for me. Hope same will work for you as well.
