评分5星,满分5星

Came back to upgrade my review to 5 stars. After the Thunderbird stuff-up my Office account eventually reappeared but Sent emails were disappearing. Emailed a query to the developer who replied within hours to look in Account settings>Folders and Copies. (I had wrongly been looking for a fix in Sent Items>Properties). Sure enough, sent items were getting stored in the native Thunderbird 'Local Folders' sent folder. Redirected that to my Office sent folder and all is good again.
