Outlook.com emails have been deleted from the past

Hi Support,

Have a issue where there is a massive gap of emails that appear to be removed from my account from 2005 - 2007.

95% of my emails from this period are gone. Some emails still appear. From 2008 - onwards they seem all fine.

I have checked the following.

Check if Conversation Threading feature is turned on. You can click here to know more about Conversation Threading

Check if they are using Sweep to schedule a cleanup. Click here to see what Sweep can do.

Check the POP settings in your web User Interface (make sure it’s not set to delete emails from server)

And all the settings are correct.

Please can you restore my emails from this period as i am trying to find a couple of emails from certain people.

Thanks
