Hotmail name changed

Hi guys

Not sure what section this best fits but has anyone ever had issues with their hotmail/outlook acc whereby their display name randomly changed? At work today I got emailed by my wife who has hotmail. My work client is outlook and i was baffled when the display name of her email was suddenly 'ClaimsTax UK'??? Totally baffled. When we logged into her account via browser her display name was set as this. Not something we would ever have done ourselves. I have edited it in the account profile back to her name but this is a concern. Does this sound like hacking or maybe MS getting into a pickle. I know outlook.com has had some issues in the past too but never seen anything like this before!

Thanks

Unfortunately it’s not a specific machine. It’s her display name in browsers for her Hotmail/MS account. Whenever she sends an email from any device it displays her name as ‘claimstax uk’. I logged into live.com and saw her display name in her had changed, so changed it back to her name and this now shows correct. But all emails still show this wrong display name, so I logged into her mail acc via outlook.live.com and can see her display name in here is still ‘claimsuk tax’ but not able to figure out how to change it

Browsers maybe infected....scan all of them.

Also look into the fact that the said email account has been hacked. On that premise, make all changes you would like and then change then password.

Ok, we are puzzled. It’s not infected machine because I tried logging into her acc at home, on work pc and on our iOS smartphones and all show her display name incorrect. It seems like an acc hack rather than infected machine(s). Whilst we will change passwords etc the immediate issue is how can we get outlook.live.com display name changed? It’s now correct in account.microsoft.com but not outlook.live.com and unfortunately this is giving all recipients the impression they are getting mail from this person called ’ClaimsUk tax’

thanks

Thanks for suggestions. I finally got home after trying to access all this through the useless iOS safari browser. To my horror as we logged into my wife’s account her display name on the pc changed to the claimstax uk. It was changed under settings - accounts too. So I accessed her acc from within the pc log in where it opened edge and had her acc details and changed her profile name. Well, her name was already there but I just clicked edit and saved. Logged out of pc, logged back in and name reverted to normal. Went onto our other pc and logged in as her, horror as name changes again to claimstax (UK) so I did the same on this machine and name reverted back to normal after logging back out and in. Tested both pcs and the correct name seems to of stuck ok and her emails are now sending from her iPad and phone with the correct display name so hopefully this will be ok now. I am still baffled as to how it ever changed in the first place.

always, always, always use 2 factor authentication.
