Answer 1

Hi @Ranga Prasad Konanki,

Currently Graph API doesn't support, add/update/view attachments of list item. You can upvote this feature request attach files to list items, based on the people requesting for this feature Microsoft Product team implement the feature.

As a workaround, you could use rest api to upload attachment files

/_api/lists/GetByTitle('" + listName + "')/items(" + itemId + ")/AttachmentFiles/add(FileName='" + file.name + "')
