One of the problems with New Outlook :

After accepting an updated invite, the original invite in calendar is not updated.
If I switch back to classic mode, I can't see the entries I have accepted under New Outlook.

Anyone has a solution?

Hi Jimmy Ng,

Thank you for reaching out to Microsoft Q&A forum.

Based on your description, the meeting update does appear to reach the mailbox, but Outlook (new) on Windows may not be refreshing and applying the change to the existing calendar item after you accept the updated invite.

Check the meeting in Outlook on the web

Please open your calendar in Outlook on the web and verify whether the meeting shows the updated time or details there. This helps confirm whether the mailbox data is already up to date or if the behavior is limited to the desktop app.

Reset Outlook (new)

If Outlook on the web shows the correct information but Outlook (new) does not, please try resetting the app:
Close Outlook (new)
Go to Windows Settings > Apps > Installed apps
Find Outlook (new) > Advanced options > Reset

Confirm both apps are using the same account/profile

Please ensure that classic Outlook and Outlook (new) are signed in to the same account and profile. If different profiles are used, calendar items may appear missing when switching between versions.

Please feel free to let me know if you have any further updates, thanks.

Step 1 - I have my yahoo mail account set up in Outlook app. So when I login to web outlook using my microsoft account (which is my yahoo mail address), I get a completely different mailbox and calendar.

So I am not sure now which calendar I am using on my app which has my yahoo mail account and calendar set up.

Hi Jimmy Ng,

Since the Outlook app is set up with your Yahoo account, the calendar you’re using there belongs to Yahoo. When signing in to Outlook on the web, using the Microsoft account that shares the same email address creates a separate Microsoft mailbox and calendar, which is why the data looks different.

Because of this:

Meetings accepted in Outlook (new) while using the Yahoo account stay in the Yahoo calendar

Switching to Classic Outlook or Outlook on the web with a Microsoft account will not show those entries

To keep calendar data consistent, please make sure the same account type is used across:

Outlook (new)

Classic Outlook

Outlook on the web

If the goal is to manage meetings in one place, it’s best to continue using one calendar only (either Yahoo everywhere, or a Microsoft mailbox everywhere).
