The outlook title bar takes up to much vertical space. It could be 20% less tall. Vertical space is a premium

I now can't move a folder so it is a subfolder of another folder. I need to create folders that will be subfolders of a major folder.

(This is a deal breaker for me. I'm moving back from the beta version.)

I need to be able to see more emails than I can see. The immediate impression I have when my inbox comes up is negative. Plus, I really hate the "Focus" vs. "Other" thing with either version. The other day I NEEDED to find an email for a friend who came by the house for the file I had inside the email and I could not find it because it was in the "Other" section which I didn't learn until the next day. Because of that incident alone I am looking for a new email carrier.

Delete all in junk folder also deleted my inbox folder and delete folder. I'm not happy with this sh!t.

Terrible. I can only view a few messages at a time whereas before I could view loads of them at once. When you have a few hndred (or more) emails, how can you easily select which ones you want to delete or move to a folder?
Trying ti fit too much on the oe page. I've gone back to the old version

Delete all needs to be more efficient. Outlook locked up after I hit delete all in my Junk Mail inbox. I had about 77 items when it hung.

Sometimes I read an email ... and I want to go back to it
later, but when I do, I can't find it. It would be nice if I
could put a star by it or something. Maybe have several
different marks you could use ... like one for an email I want
to forward later, another I want to remember to use before
it expires ... and so on.

After searching for messages (All Folders) I opened a couple messages in the results. When I clicked back to return to the search results, the messages I had opened had disappeared from the search results. I did not click on anything else to delete or mark as read. I returned to the inbox and did the same search again but the messages are still gone. Where? I want to decide in the search results list to delete, mark as read or unread, or move the message to a different folder.

Add the function to be able to show 2-3 different time zone would be perfect, as I have to arrange the meeting in different time zone so often....!!! I am sure that I am not the first person to think about this!!!

I want to be able to edit an email that I am forwarding.

Put the sender, subject and received date on one line so we can see more messages at a time.

Move To - After Search add to list - Do not immediately send email to folder found by search - A 2 step process is preferable

I want email only. No (zero) online interaction!

Cannot find the emojis or change font colour etc

Email notifications for shared calendar events received by the user with whom a calendar is shared have an incorrect time stamp:

try to design better a better user interface with security. As I observe there is a bug or defect can say that is if I use the beta, the security for a user like a theme can't change etc is not working while using this new beta.
