Your hotmail account is created as a guest account in the tenant. It looks like your account locked due to some reasons.
You will have to contact global admin of the tenant and ask him to re-enable the account.
Global admin has to run below commend to re-enable your account.
Set-AzureADUser -ObjectId "xxxxx.onmicrosoft.com#EXT#@xxxxxxx.onmicrosoft.com" -AccountEnabled $true
If you do not know who is the global admin you can ask any of you peers to perform below steps to find the global admins.
• Open Windows PowerShell as administrator.
• Run command “Install-Module azuread”
• Once installed you can run command “Connect-AzureAD” and enter user credentials once it asks for.
• Once you login, you can run command “Get-AzureADDirectoryRole”.
• From the output you can copy the object ID of Global administrator
• Run command “Get-AzureADDirectoryRoleMember -ObjectId "Paste the object ID of global admin that was copied earlier"
• You will get the list of users with global admin role assigned.
Now you can contact any global admin from the list and ask him/her to re-enable your account from the tenant.
