Outlook integration not working - send email / connection errors

Hi there, I’ve been caught on this issue for days and I cannot seem to find a solution. TL;DR my outlook credentials are not actually allowing me to connect and send an email from the specified mailbox.

I’ve established the following workflow as a simple proof of concept to automate an email digest of newly published items on a website (we’ll draw from a few if we can get the flow working and merge them).

I am running into issues with the send email node, and nothing I do seems to get outlook credentials working. I’ve tried the following:

  • Enabled app password and used an app password (also used my actual password originally, neither worked)
  • Updated our SMTP port to be 587
  • Enabled SMTP access for my account

I get a variety of errors. All to do with connecting to the account, despite this being apparently a direct connection on the cloud-based n8n as it logged in using my outlook credentials.

This is stopping us from progressing and has wasted hours for me, and will ultimately prevent n8n from being a useful tool for us if we. can’t get it resolved as most if not all of our use cases involve a “send email” step at some point or another.

Can anyone help in terms of what I might need to change, update or consider to get this working?

this happened to me before, i suggest first you try setting up the same credentials in a different instance, then copy your workflow and run it on the new instance, see if works there… when it happened to me i was doing it on a self hosted. when i tried it on cloud everything worked fine. then I updated my self hosted and tried again. Everything was working afterwards. Try if it may help
