Canvas (Known Issue) - "Invalid submission file type" Error When Submitting to Assignment with Office 365
Description of Issue
For Canvas Assignments with the online File Upload submission type where the instructor has enabled the option to restrict upload submission types to certain file extensions, students will get the error message "Invalid submission file type" when attempting to use the Office 365 submission option to submit a file directly from their OneDrive. The message appears after the student selects a file for submission and appears even if the file's extension matches a type allowed by the assignment's settings. This issue makes it impossible for the student to submit their file with the Office 365 option, and the student must use the workaround described in this document.
Students who encounter this issue should submit their file to the Canvas assignment by downloading the file from their OneDrive and then using the File Upload submission option in the Canvas assignment to upload the file from their computer.
