How can there be guests on my excel sheet that i did not give access to??

I have had Honeydew and Canarywood viewing my Excel doc when I know for a fact I only shared it with my husband who signed in as a guest with his Gmail.

So after finding this thread I simply deleted the document and proceeded to create a Google Sheets doc instead for the security.

I have NO shares and can send images - yet still says someone still Guava (Guest) Has this workbook open

Same here. Mine is "Turnip (Guest)."

I have an Excel worksheet that I have only shared with my work email address. I am the only person with access to the file and do it so I can add information when I'm at work.

I get an email when I open the file at work and DID NOT get an email from "Turnip (Guest)" showing up as accessing the file. Scared the hell out of me. Went to the share options and only saw my access and my work email address access. Nothing logged for "Turnip." I took away access to the work address and renamed the file.

I am very worried about this. Microsoft we need answers.

YES THE SAME THING HAPPENED TO ME!!! I opened an excel sheet shared with my daughter VIA EMAIL... ANd all of a sudden two dots popped up SHAKA and someone else were viewing my file, I couldn't unshare as they weren't anywhere to be unshared, they couldn't be clicked on, there was NOTHING I could do, EXCEL HACKED??????? Did they install something on my computer now? AM I AT RISK???

Does anyone know if Microsoft has addressed this issue…I had Jacaranda and Sweetgum as guests on my word document shared with one person. I removed their access but these guests won’t go away. Finally Sweetgum went away but I still have Jaracanda. This is definitely a security issue cos I can’t even delete or rename my own file. SMH, the really need to come up with a solution. Or do they need it to trend on social media before they act on it. This is really creepy and giving trust issues
