I was using Edge on my personal device at home browsing stuff and realised I was logged in on Bing.com with my Microsoft work account. I cleared my browser's browsing history and also Bing's browsing history for my work account. I am sure I saw some ads while I was browsing in some websites.
I am using Microsoft products (Word, PPT, Excel and...) on my personal laptop with my work account. In my PC's Setting under Accounts my work account was connected as well as under Email & accounts at the time. Under Privacy > Activity history the "Store my activity history on this device" and "Send my activity history to Microsoft" was ticked and my work account was under Show activity from these accounts and it was On.
I also had my personal account in the Edge browser and the Sync was on. I removed my work account on my personal laptop before using my work laptop.
I don't use my personal laptop often and I had no Idea my work account was everywhere. Does my work know about my browsing history? Thanks.
