Hi @Stanislas ZUIN

Thank you for posting your question in the Microsoft Q&A forum.

To assist you better, I will need more information.

Where are you meeting this issue (Outlook Web, New Outlook, Classic Outlook for Windows, Outlook for Mac)? Please check in Outlook Web since this it interacts directly to the server.

Is it a Team meeting or a normal meeting?

Do you see the meeting in your calendar?

Are you using a personal or a business account?

If possible, can you provide some screenshots?

You are mentioning about these sets of buttons, right? if not, please provide some screenshots. User's image

I look forward for your reply.

-> yes the buttons displayed in your previous message are the right ones. These are missing from a couple of days now (last invitations I could reply to are back end of October), thus I am questioning if any MS updates could have caused the problem. Thanks in advance.

It can be due to the calendar synchronization problem; you can try remove your account and add it again to force a resync to the server.

If that doesn't work, try reverting to Classic Outlook to see if it helps.

Yes I did, it is ok now with Classic Outlook. So much time lost... the new Outlook should not be released with such bugs.

Answer accepted, although reinstalling an older version of Outlook is not what I expected from Microsoft

Hi @Stanislas ZUIN

I am sorry about this inconvenience.

In the New Outlook, have you tried logging out and in again?

This would force a resync for your calendar.

Yes, many times, but this does not modify the absence of the accept / decline buttons on incoming invitations.
