For the past couple of months I've seen something odd happening with SharePoint Online. Once in awhile when I make changes to a file on SharePoint and choose save to upload the changes there is a "Web File Properties" dialog box prompting me for my IM credentials. I leave it blank and choose ok and it uploads like it regularly does but I'm looking for a way to prevent this dialog box from popping up.
1. The files being uploaded are Microsoft Word 2003 xml files.
2. I have full control permission for this list in SharePoint.
3. It happens only in one specific folder.
4. It's been happening for a couple months now but no major changes have been made that I'm aware of.
5. I've included an image.
-Any help would be greatly appreciated. Even a link pointing me in the right direction.
Thanks
