Deleting individual files/folders in ~/Library feels risky - what if this causes the Mac not to boot?
Reluctant to try uninstalling Mac Office 2016 and re-installing because Microsoft does not provide an uninstaller tool.Tried using 'Rebuild' on a folder in Outlook as suggested in a forum post - waiting for indexing to completed.Used 'Outlook Profile Manager' to create a 'new' profile and re-created email accounts from scratch (imap accounts, if that matters).Tried 'mdimport -L' to confirm that there is only 1 Outlook importer.Tried workaround suggested above (dragging profile to Privacy tab and then removing it.and waiting for indexing to complete).Curiously, macOS Spotlight will show email search results but not Mac Outlook. Running Mac Outlook 2016 (version 16.16.12) and 'No Results' is shown when trying to search for emails. Upgraded from Macbook Pro (late 2016) running High Sierra to Macbook Pro (2019) running Mojave 10.14.5 using Migration Assistant and Target Disk Mode (on old Mac).
