  • I can take a look. Can you DM me the recipient email address please?

  • Sure. Sent :)

  • Thank you. It looks like the sending server never reached out to the recipients. Can you have the user try sending again but this time type the email address and if it tries to autopopulate then please delete and re-type it in manually. Then type the email address again and try to send. I don't see that message hitting our servers.

  • Some sort of Outlook issue?

  • It looks like it could be a cached issue, yes.

  • Okay thank you, that seemed to do the trick
