The Office 365 Home / Microsoft 365 Family subscription has a premium option which allows you to use your own email domain.
However, there is no option to enable the DKIM security measure in the premium interface for your own personalized email addresses / own email domain.
Without DKIM, outgoing email often ends up in the recipient's Spam folder, because the mail is not signed and authenticity can not be verified.

Can you enable the option to enable/configure DKIM in the outlook.com UI for Office 365 Home / Microsoft 365 Family subscribers?
(just like you enabled the personalized email addresses in the past with your partner GoDaddy)

At this moment DKIM is enabled as a security & brand protection measure for the default Microsoft domains outlook.com/hotmail.com/live.com.
The same functionality should become available for the personalized email domains hosted on the outlook.com infrastructure/platform.
Also, because the feature itself is already implemented and available in the Business edition, but requires the Admin panel which does not exist in the outlook.com UI.

There was a great feature that let you choose to block the entire domain when you chose to block an email. This was great because I used to have to go through the blocked senders list one by one adding the bad domains. I thought it should have been expanded so that if you chose to block a domain, it automatically deleted all emails from that domain that was in your mailbox.

Instead of expanding the functionality, it looks like it has been removed. Bring back the option to flag email as Junk, block it, choose to block the domain, and then delete all emails from that domain. it would make cleaning up your mailbox so much easier and faster.

The overall issue is darkmode is very hard to work with as a developer, until recently we could override certain things that were breaking but the recent update adds !important to the inlined styles so we can no longer fix the bugs it causes.

A few of the bugs that we’re facing include...
Light colours are adjusted but dark are not, leading to a lack of visual structure where contrast is being used.
When dark text is applied to a light background image the text is made light but the background stays the same making it very hard to read
Transparency is lost, weather it’s done via rgba, 4 or 8 digit hex codes or via the transparent keyword in darkmode it is always converted to fully opaque colours
When the OS is in darkmode and Outlook is in darkmode, colours defined in (prefers-color-scheme: dark) stay unchanged in the media query but are inlined as different values on the element with an !important tag, meaning the intended styles are lost. When Outlook is in light mode and the OS is in darkmode this functions as expected

Users are loving dark mode but new issues are surfacing all the time, as email developers we need a way to work with darkmode but that is currently being blocked. Even emails from Microsoft are showing a number of these issues. Looking at my inbox it’s hard to find an HTML email that isn’t facing at least one of these issues.

Possible solutions could include
Looking at a way to apply styles from (prefers-color-scheme: dark) when outlook dark mode is switched on

Allowing dev to bypass changes when issues are too complex to solve, either meta tags or maybe :root{color-scheme:light ;supported-color-schemes:light }
A beta version of outlook for email devs to flag these issues before they hit production, or at least to be able to find some workarounds

"Move to" then changes to "copy to" and it is confusing as to the operation being performed. When you choose to "Move to" for an email, the pull down box then changes to "Copy to" <folder name> and it is confusing terminology. Is the email being moved to the new folder completely? Or is a copy being moved and the original left to clutter up the inbox as well? Since I don't see the email still in the inbox, it does appear to be acting as a Move but it is confusing terminology since Move means "move to new location and delete from original location" and Copy means "send a copy to a new location while leaving original in its starting location"
