Calendar continuously wants to update from previous ward council position

The calendar continuously wants to update from previous ward council positions. The leadership provided information on how the ward calendar could be updated to your personal email. I am no longer in that position and a Windows security screen pops up wanting for me to log in to update. Windows does not show my login is correct and it pops up every 5 mins or less. I also can not delete the old meetings on my calendar. Thanks for your help.

This isn't coming from the church calendar. I think you've got a program on your PC that is trying to sync to the calendar. Perhaps Microsoft Outlook. You'll need to turn that off or at least update the link.

Here is the link that was supplied on how to set up the sync with Outlook. You can probably use that as a guide on how to turn it off.
