I’m working on an n8n workflow to send Email using Outlook node.
I’m looking for a solution in n8n where I can send an email on behalf of any user within our organization, with the email sender being dynamic, I need to be able to specify the sender’s email address as any user within our organization and dynamically.
Hey @Mohamed_Arafath,
Welcome to the community 
It looks like the Outlook node has an option to specify a From field but… if you are using Microsoft 365 it gets complicated as they cracked down on being able to send from unless the correct permissions are set on the mailboxes or you use a relay which can be a nightmare to set up.
Technically what you want to do is possible it just all depends on your mail server and if you are able to set it up.
