Wrong Data Being Synced to iPhone 7 Calendar App from desktop Outlook 2019 Calendar
What Outlook folder/file on my computer does iTunes use to sync the iPhone calendar app to my desktop Outlook calendar (in iTunes Settings/Info select Sync Contacts with Outlook)? The data in my default Outlook .pst file (which is where my current Outlook calendar entries live) is not what I am seeing on my iPhone. I am seeing very old/non-current data on my iPhone which does not match any calendar in my Outlook calendar list (under either My Calendars or Other Calendars) so I'm not sure where that data is coming from. I believe there must be some other file on my computer that has old calendar info on it that is getting synced to my iPhone calendar instead of the current .pst file that matches what I see when I look at my desktop Outlook calendar, but I don't know how to find that file. The correct file is listed as the default file so I believe it should be the file being used for the sync. I tried to sync via iCloud instead of via an iTunes sync but the same incorrect data gets synced this way also, so somewhere there is a file being used for syncing that is not being updated every time I update my calendar in Outlook on my laptop.
iPhone 7, iOS 13
