In Outlook 365 for Mac, I have multiple calendars in my account, only one which I use regularly. Whenever I click on the "Calendar" icon, every calendar in my account is selected. I have to manually deselect the lesser used calendars every time.

When I uncheck a calendar, I want that calendar to stay unchecked until it is selected again. I do not want the calendar deleted, or removed from the list, I just want it to stay unchecked.

Enable Drag and Drop for Outlook Mac Groups, as its pretty useless without, especially as your tech support staff tell me you're removing support for Public Folders in the future

I would like to be able to keep the Group by Category option set on my Inbox, but for Sent items, I would like it to always sort by Date Sent. I think this feature may have been lost in a recent update.

By right clicking on the dock icon, it would be great to access the "New item" menu. I don't need to see the main Outlook window if I need to create a new email, note, appointment.

Having recently moved to MAC ..... I find the search capability on Outlook mail very frustrating. Simpl things like on a PC .. I could click on 'from column .... type ..Joh and it will sort tos how all mails from name - John On a Mac is ai type Joh ... only last letter is used ... and will sort to fhow 'h'
Compounded by very poor seach in teh search bar ..... it is very unreliable seach .... and does not seem to support 'Adv' search options as on PC

On Outlook for PC .... when a Calendar invite arrives - it automatically puts a 'greyed out' copy into a calendar view. This feature is missing on a MAC .... which means it is easy to miss an invite when you have a busy inbox. It is a great feature of Outlook ..... should be there for a MAC

As it stands, any Mac user with Catalina operating systems are unable to mark incoming emails (in shared email accounts) as spam or as well as Blocking senders. It works fine on a Windows operating system however not at all on a Mac. Junk options are greyed out.

Unlike Outlook on Windows, Mac users cannot edit the Teams meeting details before the invite is sent. This means you cannot add additional international dial in numbers to the invite which is very frustrating.

It is great to have my flight automatically show up on calendar but it does not factor in boarding time and allows people to book during boarding. It would be ideal to have an option to set a buffer time for the automatic meeting. For example for flight I might put 60 minutes buffer so if my flight is from 12:05pm-2:50pm then the calendar would book for 11:05 am to 2:50pm or create two appointments for pre-flight and flight. Same would apply for event, dining, and service events.

I need the ability to sort first by one column in my outlook (let's say "From") and then sort the "date sent" column too. It doesn't help to find a whole string of emails from myself that I've saved in a folder, but then have them appear in a date order that I can't see the rationale behind at all.

Currently if you sort tasks by Due date it displays as follows:
Ascending order
– No due date
– Soonest dates
– Furthest away dates

Descending order
– Furthest away dates
– Soonest dates
– No due date

Wouldn't it make more sense for those with 'No due date' to come after the Furthest away dates, so that you're most pressing tasks can be ordered to display at the top of the list?

make the footer bar optional, possibility to hide it
It only consumes space and does not provide any value as there is only the number of mails and the sync information

When inviting people to a teams meeting on the Mac the meeting details are added to the bottom of the email and people often say that the joining information is missing however if this was at the top of the email /invite it would be easier and more obvious when they are joining the meeing.

It is so slow to detect that it is on internal network. At least 2-3 times a pop up displays. After that couple of re-authentication pop up, even though credentials are stored in keychains. Then it starts working.

Also, there is no auto reconnection when connection is lost. Why???

It would be very useful if you can add a reminder based on a calendar sheet instead of showing the date and time.

Add the Outlook for PC facility to print an entire email chain to Outlook for Mac

It would be nice to be able to create notes within an email for personal use/reminder.

The idea is to have an Icon next to the other Trash, Archive and Flag Icons.
When you click on Notes Icon it pops up and you can make notes or see your notes about that email.
