Why is somebody elses Twitter account appearing on my hotmail?



I manage several different companies Twitter accounts on their behalf but am wondering how I stop one of the companies logos (which is not my company, I just manage their account - https://pbs.twimg.com/profile_images/1792260227/PHONE-AND-PAY2.png), appearing on my own hotmail account?

If Twitter has to link to my hotmail account which I still consider an invasion of privacy - please can it at least link to my own account @VAJunkieCo and not another company’s Twitter account?

This is really frustrating and I have tried everything to remove their logo from my own company email!
