Hello - I am running calendar version 10.0.01.11 on a Samsung 9+ (android version 9) and noticed this morning that calendar sync was not functioning for any of my Office 365 accounts. All past and future events had disappeared. Since then, some past events have reappeared though all future events are missing both from my android calendar but also on the web and desktop Microsoft Outlook apps (laptop is a dell thinkpad p50). I have tried un-syncing and re-syncing, rebooting all devices, running the virtual assistant and am waiting for a call from Microsoft support. This has the potentially to significantly impact my business and any help would be greatly appreciated.
