Starting Outlook with /ResetNavpane switch might solve the issue - but would also wipe out his (many) custom Groups and Calendars.ĭoes anyone know of a way to reset local NavPane settings and load from Online?

When accessing all folders and Calendars are present.It definitely seems to be an issue locally on the new PC Running Outlook in Online Mode, instead of Cached Mode.'Calendar Groups' are only partially populated - with some Groups containing no Calendars - and others containing one or few calendars.'Favorites' only contains 'Sent Items' - and not his five other custom folders.One of our colleagues got a new PC and his Favorites and Calendar Groups are not properly synced from Exchange Online in Outlook 2016.
