Many thanks for both replies, sadly it seems I have learnt a harsh lesson, and been held captive by Microsoft.
I have used my existing gmail account to try and reset the Hotmail e mail, and despite filling in the on line form for MS they tell me they need more information including any passwords associated with the account for the last 20 years.
The biggest issue I have is that I do not have access to the email addresses of my contacts, and also no access to the archived e mails, surely there must be a way to access them?
So now seriously considering replacing PC with Chromebook as windows 10 will not be supported after October anyway, and setting up alternative g mail addresses for different parts of my life, eg banking, caravan, car, family etc, hopefully this information will help somebody else on here before MS decide to interfere in their lives.
Also the sheer frustration of dealing with what is clearly AI and them telling me that 'this sytem is not working right now' when it is them that have blocked my account and are unable to give a specific reason, quoting 'suspected' unauthorised activity, nakes me realise how stupid I have been to rely on them, perhaps think myself lucky it didn't happen last week when I was in France
I am done with Microsoft
