Microsoft Outlook is already my least favorite email program ever. Every new edition of it reaches an even lower low.
Behold #Microsoft 365 Outlook. It's a fitting name for the champion of worst in class products. There are 365 days in the year and on every single one of those fucking days my Microsoft products ruin them.
They released a calendar and email manager that doesn't let you export your email or calendar unless they were tied to a proper Microsoft Outlook service. That means you can setup your own mail service, save a bunch of shit to your MS Outlook and now you can't move it. It's fucking stuck on an island with no obvious way to export it.
Good job Microsoft! 👏
BTW, I don't need suggestions for new mail programs. I don't use Outlook. I just have clients who do and so I have to help them figure out why nothing ever works.
