What happened with Outlook will happen again.
Before you jump to another host, consider #selfhosting.
In 2026 you can have a fast and secure mail server of your own, easy to admin & update without a compsci degree. One that is tightly-secured, supports all mail clients, has top delivery & encrypted storage. All under your control, & your domain.

We'll pick a date as a group, & I'll guide you all through the build.
@JulianOliver I love this idea, but I thought that self hosted emails often get rejected as spam by a lot of other hosts?
