A Microsoft file hosting and synchronization service.
Some people I support with some IT stuff experience this same issue 100% with personal paid accounts:
- shared folders are converted into shortcuts and locally removed
- duplicate folders are created in local OneDrive with the same name, followed by "- [My Computer Name]"
Reading this forum thread and various others (this MS community, reddit, etc.) makes it clear something really bad is happening within the MS software. The increased activity here since February 19/20 maybe indicates something happened then?
@Microsoft: please fix this for all customers. The ones who are mentioning it here are just the tip of the iceberg. I think the issue impact thousands and even more paying customers.
