One of our users is also getting this issue, and it's turned up in the last few days. They are accessing another user's calendar that they have permissions on, and when accepting an item it duplicates that item on that calendar.

- I fixed the issue!
I did the next steps in the classic Outlook (Windows):
1. Exit Outlook and Skype for Business.
2. From the Start menu, choose Run.
3. In the Run window, type this path in the Open box "%LOCALAPPDATA%\Microsoft\Outlook\"
Click OK
4. Find the .ost file and rename or delete it (you may need to Show Hidden Files and Show Extensions to see the file)
5. Remove the following files: any .xml files, any .nst files
6. Open the RoamCache folder and delete all items
7. Open the HubAppFileCache folder and delete all items
8. Open the Offline Address Books folder and delete all items
9. Open the 16 folder and delete all items
10. Restart Outlook
