How to correct meeting requests appearing twice in Outlook calendar?

Question

How to correct meeting requests appearing twice in Outlook calendar?

Damien 60

Using Outlook 2021 with Exchange 2019 on premise.

The calendar of one of our users displays twice every event for which she receives an invitation. All events and meeting requests she creates are not impacted by this issue.

We have already tried multiple actions to solve this, without any success so far:

.ost file deleted
in Outlook Web access the invitations appear only once, same thing in Teams
Archive .pst removed from OneDrive
When the calendar is shared with another user, this user also sees the duplicate meetings

Does anyone have a hint to help us remove these duplicate items?

Note: I have already posted the question on general MS Q&A, and was advised to repost it here:

Hi @Damien

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

Based on the information you have provided, looks like the meetings got duplicated.

Since I don't have the exact environment like yours, I'm unable to reproduce the case but I will try my best to help.

Have you tried some common troubleshooting?

Windows + R then type %LOCALAPPDATA%\Microsoft\Outlook\
Remove the following files: any .xml files, any .nst files.
Open RoamCache folder and delete all items.
Open the HubAppFileCache folder and delete all items.
Open the Offline Address Books folder and delete all items.

Please let me know if this works for you, if not, we can try another approach.

I look forward for your reply.

Hi @Jayden-P , due to the holiday period I have not been able so far to perform the actions you recommend. However this phenomena also appears when I add the user calendar to my own, so I expect this is not due to local files that need to be cleaned.

Hi @Damien

Since Outlook web is working properly, this issue might come from the desktop app.

You can try repair online Office application.

Repair an Office application - Microsoft Support

If clearing roam cache and repair online don't work, my last solution is creating another Outlook profile.

Create an Outlook profile - Microsoft Support

If the issue persists, please raise a support ticket via Admin Center.

Hello Jayden, thank you for your input.

I finally managed to solve the issue: it was actually a rule on the user Inbox which moved any meeting request item to the Calendar folder. I simply had to disable this rule.

Weird, but at least it's solved!
