So what happens if you give them edit privileges? My experience has been that to have one drive update across pcs, each pc has to have the same one drive account (ie. same e-mail owner). Other wise, you need to send a share link to your file with edit privileges to each person. They can then go to their one drive folder location(with the sync turned on using the code as linked) then right click One Drive personal, select View Online, select shared, select the file then download to their pc. The user would then have your file to access, edit as needed and save back to one drive. They would then need to send you a link to the file with edit privileges which you could then repeat the process of navigating to your one drive folder location(with the sync turned on using the code as linked) then right click One Drive personal, select View Online, select shared, select the file then download to your pc. You only have to set up the links once but the whole process is cumbersome especially if you have more than one other person to share the file with. MS has likely made this purposefully cumbersome because they offer a Sharepoint app for sale that does what you want. There doesn't seem to be anyway to automate the retrieval of the file from a Share folder but you can automate uploading the file from your pc by saving it to One Drive directly or through your settings backing up files to One Drive. I'm not that familiar with the One Drive file exchange and I'm not even sure how you managed to auto sync with one other person? Perhaps others have more insights/experience/advice than I can offer. Hopefully they will share especially if they have figured out how to automate the retrieval of shared files. HTH. Dave
