Adding Calendar Events in the New (not improved) Outlook

Grace L 0

Why is it SO DIFFICULT to add an event in the new Outlook? I add an event for 'all day', save, and it changes it to two days. I have to go back multiple times, switching dates, times, making it 'all day' again, toggling private/not, and eventually it saves correctly. WHY?

Also, why is there no option to add Holidays to the existing calendar - not create a new one. Help support tells me that functionality doesn't exist yet. Really?

Hi Grace L

I understand how frustrating that would be. An all-day event should save correctly the first time, and repeatedly having to edit dates and settings just to get a single-day event saved is certainly not the experience you'd expect.

To help narrow down the all-day event issue further, could you please confirm:

Which account type are you using in New Outlook (Outlook.com, Hotmail, Gmail, Yahoo, etc.)?
Does the problem occur with every all-day event or only some events?
If you create the same event in Outlook on the web, does it also become a two-day event?

In the meantime, regarding the all-day event changing into a two-day event, one possible cause is a calendar time zone or synchronization issue. Based on your description, I'd recommend checking the following:

Open "Settings" > "Calendar" > "View" and go to Calendar View Settings in New Outlook.
Verify that the correct time zone is selected.
Create a new test all-day event on a future date and check whether it immediately displays as a single-day event before saving.
If the issue persists, try creating the same all-day event in Outlook on the web and see whether the behavior is the same. This can help determine whether the problem is specific to the New Outlook app or affects the calendar account itself.

Regarding holiday calendars, Microsoft's documentation indicates that New Outlook uses holiday calendars that are added as separate calendars, rather than importing holidays directly into your existing primary calendar as Classic Outlook did.

You can review Microsoft's holiday calendar guidance here: Add holidays to your calendar in Outlook

Please feel free to keep me posted and I'm here if you need any further assistance. Thank you for your understanding.

Hi, and thank you for responding.

I have verified the time zones are correct.

When I create an all-day event and click save it displays correctly for about 1 second, then spreads to two days. I open the event, correct the dates, click on private, not private and private again then save. That usually does it, but sometimes it then changes to an event with a time specific entry. So bizarre. I read that in a blog as something that works and it does, but shouldn't happen in the first place! I will try the web. When I create an event on the app on my phone there is no issue, only on the desktop version.

As for holidays, I'm pretty certain literally EVERYOE would like the holidays displayed in their calendar. That is a fix that should definitely happen. Why they are not in the calendar - or able to be added is really a bad move!

Thank you. I will let you know shortly on the web try.

Hi Grace L

Thank you for the update.

Since you've already verified the time zone, the next step I would recommend is exactly what you're planning to test:

Create the same all-day event in Outlook on the web.

Verify whether it remains a single-day event after saving.

Then open New Outlook and see whether the event changes after synchronization.

If the event remains correct on the web but becomes two days only after New Outlook syncs, that would further indicate the issue is isolated to the desktop client.

Regarding holidays, I understand your concern. At present, holiday calendars in New Outlook are managed separately rather than being merged directly into the primary calendar, which differs from the experience many users were accustomed to in Classic Outlook.

Thank you.

I can create an all day event on the web and on my mobile device and it remains a single day, but displays on the desktop New Outlook spanning two days. :-(

I certainly hope consideration will be given to adding the ability to import holidays into an existing calendar!

Hi Grace L

Thank you for testing and sharing the results.

I understand the issue much better now. Since the event remains correct when created in Outlook on the web and on your mobile device, but changes to a two-day event only in the New Outlook desktop application, this points to the issue being specific to the New Outlook client rather than your calendar data or account.

At this point, I do not have any additional troubleshooting steps to suggest beyond the testing you've already completed. Since the behavior can be reproduced and appears isolated to the desktop application, I recommend reporting it through Help > Feedback in New Outlook so the product team can review it directly.

Regarding holiday calendars, I understand your feedback. At present, holiday calendars in New Outlook are managed separately rather than being imported directly into an existing calendar, and many users have expressed interest in additional flexibility in this area. You can also submit this suggestion through the Feedback portal to help the product team evaluate future improvements.

Thank you again for taking the time to test this thoroughly and for sharing your findings. I appreciate the detailed feedback, and I hope Microsoft will continue improving the New Outlook experience in these areas.

This is still a fault in November 2026! I am having the same issue specifically with my iCal account - it saves correctly if I make the all-day appointment in iCal - but if I do it in Outlook it changes it to two days - when is this going to be fixed, it's VERY frustrating. You can see the difference below, The first screenshot is in iCal - the second is in Outlook, where it's displaying the all-day appointment 'Term 3 week 4' which was made in outlook as 2 days. It's only displaying as one day in iCal for the same appointment. The next week - 'Term 3 week 5' was made in iCal and is displaying correctly in outlook. So it appears that appointments made via outlook in ical are the issue. Can you provide a solution or investigate this further, please? User's image
