If a day to book for a recurrent meeting falls on a holiday, it should be rejected automatically and enable us to rebook the item on another day.
Therefore, it would be great if you could add such a setting.

Similar to how Swiftkey can check spelling on more than one language. Thank you.

Currently the Office 365 group calendar is disclosed only to the group members, but I want other users to see the group calendar as well. It would be great if I can let user see the group calendar without adding him to the group as a member.

Allow for spell checking in multiple languages, recently this option was changed with the introduction of Microsoft Editor, which only allows for one language at a time and needs to be set (deep) in the Outlook settings.
Before you could use the spell checker form the web browser (Edge allows for multiple languages to be checked), but this does not work anymore.

WHY NOT JUST ALL FROM MORE RECENT?

We need to be able to run mail merges through Outlook on the web, just like on the desktop app, so that we can use this functionality when working away from the office.

Can you please sync categories from the Outlook desktop application to the Office365 and Mobile versions of outlook? This would compete with Gmail's label function and boost efficiency

It would be great if we could delete items in the O365 group mailbox at once by using item retention policy, or if items can be automatically deleted when the O365 group mailbox capacity is almost full. If the mailbox no longer has enough item capacity, we need to manually delete items or recreate the Office 365 group which is time consuming for us.

Previously, clicking Inbox while a message was selected would deselect all messages. This is what I want!

Now it selects the first message and instantly marks it read, which is INCREDIBLY stupid! How am I supposed to deselect all messages now??

Where is setting to have "Read" message receipts?

Email confirmation for Microsoft Bookings displays a blurred image of the logo even if the photo uploaded to be used is of high resolution. In other words, the emails do not retain the quality of the photo used as a logo for Microsoft Bookings.

Make status work as intended, and as it does on Old Outlook

In the old outlook pinned messages would show the same things as a normal message, however now they just show the title. Now I have to open up each email to remind myself who it was from and what it was about...

Brazilian Portuguese is the most popular variant of the Portuguese language.
It is available in Microsoft Editor in Word Dektop, Word Online, and the Edge Chrome extension to use Microsoft Editor in any website.

It does not make sense to omit Brazilian Portuguese on the integrated Microsoft Editor native to OWA. this is a serious omission.

In the current version you copy and paste email addresses. it would be helpful to be able to do that in this update.

how to Spell check your emails in Outlook

We can request recipients to share their calendar with the Share Calendar option in the Outlook client for semi-annual channel. So, it would be great if Ootw would have the similar requesting feature for the calendar sharing.

With the old Outlook Experience, you could ensure that any items added to a shared calendar by another person you were sent an email notification. The actual setting was "When someone updates an event or task on this calendar, send details of the change to:"

This seems to not be available with the new Outlook experience, or hidden somewhere that is not easy to find.

Could you please add this back in, as it is most useful for Shared Calendars, and available with other email/calendar services such as Google.

When receiving email from qq.com , we start to see ? question marks in the mail for certain Chinese characters. Most likely the new outlook version does not use the default qq.com's gb18030 encoding method.

It was working before Jan 30th.
