Hi,@Glenn Maxwell
Thanks for posting your question in the Microsoft Q&A forum.
Based on your description, I have performed the relevant tests and it is indeed not possible to split the text into 5 lines, as you said.
I have tested this several times and have found that Powershell reads the text in the format it is in with no problems.
I've noticed in OWA that the auto-reply text is not populated as expected.
IMO, it is not possible to fulfill your request at this time, you can make formatting changes in OWA's autoresponder.
