Samsung S5 Neo with Android 7.0 is suddenly not syncing the calendar with outlook.com. If I originate calendar item/change on the phone it syncs with outlook, but if I originate item/change on outlook, it will not sync with the phone. I'm using the phone's native calendar app.
This issue is simultaneously happening on my husband's phone. Same phone and same app. We have had no issues for the past year. Just started recently. Help!
