Have a strange one:
Synchronizing the calendar suddenly brings up old entries that were already synced OK.
After giving up, I allowed update as suggested by the sync and on the next sync it came back but now on the opposite direction, before it was Outlook to phone and now its phone to Outlook. And it applies to hundreds of appointments.
What I did is select never sync again but every now and then, it happens all over again with random, old appointments.
With new appointments it works fine, no issues.
What is wrong? How can I stop it?
I'm on OnePlus One 5, Android 10 sync with Outlook (office) 2019.
Any assistance will be appreciated.
