don't block shutdown if emptying the "deleted items" folder on exit is on
Please don't block Windows shutdown if the setting to empty the "deleted items" folder on exit is set.
Do select a sensible default instead. Based on how autosave is behaving in other office applications, I'd say go ahead and delete without asking. Alternatively, skip the folder cleanup on shutdown and just exit. Whatever you do, just don't stop the shutdown sequence.
This is one of the most frustrating things in Outlook for me, as this usually happens just as I want to shut down the laptop and rush to the train station (this is also the reason I usually don't have time to send a feedback about it).
Why would they do away with the option to have deleted items folder cleared on exit? This keeps the file size much smaller. Are they just trying to increase the need for cloud storage and sell more storage? I can't think of any other reason for this to be gone in the new version. But I am far from a programmer, there may be some limitations of Office 365 that makes it impossible. Silly from my perspective.
At present, most files are saved to OneDrive automatically, when a file is not saved to OneDrive the reminder to SAVE has been removed at shutdown and it's too easy to forget to Save your changes.
