Hello experts :),
Someone in my company has an issue with internet calendars. He subscribed to his google agenda and the calendar appears in the "other calendar" section. So it seems to be good.
But after a while, there are "copies" of his calendar. CalendarName(1), CalendarName(2), ... (5) for example. It is like if Outlook duplicates calendar instead of overwriting the changes in the calendar.
He tried to delete them but after some time they reappears. Where does it come from? Duplicate option, sync issue ?

@kiwivert Hello, are you able to go into the Calendar section of Outlook and tried deleting them? It also could be that he had maybe set up an online sync of Google Calendar. I would check all Calendar settings. In the mean time, follow this link for some help: https://support.office.com/en-us/article/Delete-a-calendar-9BA1364C-BDB0-41BE-8F66-EAF96698D021

He told me he has already :
deleted all Outlook data files,
deleted his Outlook profile,
subscribed to his calendar instead of added it.
He told me he use Outlook on his laptop and on his phone. I wonder if it can be a part of the issue.

I have the same problem: repeated calls of a webcal - calender with c# (OpenSharedFolder(webCalString) ) creates over and over new instances of the subscribed calender in outlook.exe. Details an a code example can be found here: https://developercommunity.visualstudio.com/t/c-microsoftofficeinteropoutlook-opensharedfolderwe/153...
The Microsoft Visual Studio Team says it will be an Office problem. I still look for a solution. Any idea would be mostly welcomed!

I have had the same issue for about 3 years and still no solution - Ii delete multiple internet calendars, pst files, internet calendar folders, etc. every day or so. I have had my profile rebuilt etc. These only appear on my desktop version of outlook (occured with both 2016 and my current 2019), not the microsoft 365 online version. Hope to hear of a solution one day....
