But I can get no further. Would be very grateful for advice.

Hi @Grlang,

Can you confirm that your email meets the technical requirements for IMAP listed in this help article? Do you see a message when you hover over the greyed-out button at the bottom of the screenshot?

The more information you can include, the better the community can assist with the next steps.

Thank you,

Kristen
