Hello,
the file upload component works great. However, there is one issue - when I drag and drop a file from outlook it uploads the file but deletes it in outlook afterwards. I did a quick research and it seems other people have faced similar issues when working with outlook (not with syncfusion components). One user wrote "I may have found a potential solution. The emails get deleted due to the dropData.action being set as ‘move’. If it’s set to ‘copy’ it seems to resolve the problem. This is based on the Javascript code. I have not tested it."
