Because creating an HTML email seems to be above me on my mac, I’ve stared using MS Outlook for Mac on my mac. Due to a mess up with 123-reg everything before a few months ago is in an archive on my mac stored as Mbox files. To import them into Outlook they need to be pst files.

Searching the web it looks like there’s a plethora of programmes that cost money and look to be from dubious sources. Surely it’s not that much hassle?

Anyone done it without gifting their credit card details to some scammer?

Export from Mail as box and then import directly into Outlook. (See here about 4 down the page)
