Configuring preferences and options in Outlook on the web for business
Dear Kurt Johansen2,
Good day.
I apologize for any confusion. To disable the auto-save feature for email drafts in Outlook on the web.
After thorough research, testing from my end and consulting, it’s been concluded that there is not currently feasible to disable auto-save feature for email drafts in Outlook on the web because there is not such us feature in outlook on the web. Since emails action are sync between outlook desktop and on the web so any action from outlook desktop will be reflect on the web. You need to disable it from outlook desktop.
