Microsoft Outlook Error: The Operation Cannot Be Performed Because the Message Has Been Changed

This message appears when editing a draft email in outlook and generally when using IMAP with/without a flaky wifi. The solution is simple: Solution # Open Outlook, File -> Options -> Mail. Uncheck all options under “Conversation Clean up”. Save, quit Outlook and restart Outlook. Workaround # If you don’t want to or cannot spend any time tinkering as explained above, you can use the online version of Outlook at either office.com or outlook.com. Online versions are not affected by this issue.
