I have recently upgraded my HTC ONE A9 to Nougat (Android 7.0) and had problems with my HTC Sync which had been working fine until the upgrade. I was told to uninstall HTC Sync Manager on my PC and re-download the latest HTC Sync Manager software from HTC United States. I did this successfully and re-installed the software and drivers using the download. Now all my Outlook Calendar items have synced but have remove the reminders, changed all the colours I put into events in Outlook and even compressed events which last more than 1 day into 1 day in both my phone and my Windows 10 PC (running MS Office 2016). Any ideas? I just spent at least 1 hour updated everything back into Outlook and I'm worried to re-sync with my HTC one in case it changes everything on Outlook again?
Thanks for anybody's help.
