Hello @Shannon M ,
Thanks for reaching out.
Hope you are referring to consumer account (Microsoft Account Outlook.com), if so then based on your selection either 30/60 days while closing account that's when Microsoft permanently close your account and delete all related personal data.
However, I would recommend you to ask the experts in the dedicated Community forum over here since Microsoft Account is currently not supported in this Q&A forums, the supported products are listed over here https://learn.microsoft.com/en-us/answers/products (more to be added later on).
Hope this helps.
