Also, I think you used to be able to mark a follow-up flag "complete" for drafts. For example, in a shared folder if someone has a follow up to review a draft before another person sends it, it would be nice to be able to check the "complete" check mark so the author can easily see it is OK to be sent. This recently changed, I believe. I believe this was possible as recently as a week ago.
The way we enter search terms and folders needs to be improved. It is sill that if you change folders your search terms disappear. The folders searched should just be an additional filter selection to add to the search terms and other Boolean operators. Also, can you please allow quotation marks to mean search the literal group of terms rather than putting an "or" between each term. I'd like to narrow the search with additional terms, not expand it.
Outlook desktop opens all mailboxes for which a user has access. Could Outlook for iOS work this way too? In other words, do shared mailboxes work in iOS?
But also I am able to see other employee mailboxes too in Outlook a Desktop. So would like that too.
