Moving a domain name email to MS365

[#1]

Hi. As a Plusnet customer I have two email addresses, one using Plusnet settings, that I've managed, with some difficulty, to move to 365. The other uses a domain name purchased from Namesco for incoming but Plusnet for outgoing as I haven't (yet) purchased an authenticated SMTP. This one has proved a nightmare despite 'help' from MS and despite working perfectly happily on Office 2010 for many years. I also note that it doesn't appear on Webmail despite the outgoing settings being Plusnet's. Should it? And does anyone have any bright ideas about moving to 365?

Thanks

It wont appear on webmail unless its hosted by PlusNet. Using the plusnet smtp server for sending mail from a domain hosted elsewhere is not a good idea UNLESS youve set an SPF record to include the plusnet servers in the authorised list.

As far as the spf record goes @MisterW helped me to set up my Namesco email account see here. https://community.plus.net/t5/Email/Static-IP-SPF-fail/m-p/1877365#M40018
As fas as MS365 I tried it and went back to Office 2019 out of sheer frustration. The good bit about 365 was that Microsoft immediately refunded the licence fee.

Mister W thanks for the advice.
