Has anyone else experienced this? We are O365/hosted SharePoint. I honestly didn't believe it when it was reported to me by other users, but now I've seen it for myself. The version history (showing document saves) in a library sometimes shows the wrong username - in this instance me, even though I did not have the document open, instead of the user whom I know to have been working in the file, alone, at the time of those saves. I did have the document open previously today, but had long since closed out of MS Word completely. Most of us are in Win10 and we only use the full client application of Word, not Word Online (for a host of other unrelated reasons).
Is this a bug? Is there a fix? It is making collaborators in other departments uneasy - and we have enough trouble with SP adoption.
