Does anyone know what this redish/purplish vertical line is?

When I hover over it, I get my name popping up but I have no clue what it is. I tried to turn off review tracking and commenting all to no avail.

Can you upload a copy of the document so that we can investigate.


Hi Doug,

The problem is now gone. I don't know exactly why. I think it might have to do with the fact that I had one instance of word with the document open running on my main pc, and I was editing the document on my laptop, which was stored on my OneDrive.


No further investigation needed.

Thanks for helping out.




My guess is that you were seeing the "flags" that represent different users in a co-authoring environment. Since the document was open on both your PC and your laptop, Word/OneDrive identified this as two different users. 

That makes total sense.
