Note: For files saved in Compatibility Mode (.xls, .ppt, .doc), the Dropbox badge will not show when another person is viewing the file and it won't prompt you to update to the latest version of the file. To ensure the badge is reporting accurately, please use Save As to save files in a non-Compatibility Mode file format (.xlsx, .pptx, .docx).
Also note that timing and exact functionality of these features may change from what's shared here, and Dropbox does not provide warranties on the performance of these features.
