Windows 10: is this official Insider email address?

Hi, I just got an email from this "*** Email address is removed for privacy ***" because I signed up for it some time ago, but is this official address? or should I block it?

:)

 

Win10 Mail - where's the address book?


That’s now the People app.
If you know the contact's name or email address & they’re listed in the People app, you can start typing the first few letters of their name or email address and Mail for Windows 10 will suggest matching contacts.

 

Mail App: Removing drop down email address suggestions


I'm not a big fan of the MS Mail program and don't really use it for serious stuff but somehow or other if I create a new email then as I start to enter the recipients address a whole load of suggestions will appear. I don't have any contacts in the People app so I'm not sure where these come from.

The question is how can I clear this list so that I no longer get the suggestions?

Thanks

That's what the auto setting will do since you're over the 1333 mark it jumps to the next step which isn't listed or officially supported I assume by that ram.

At this point though I would suggest dropping the multi one step or .5 so that we can get something stable and possibly take the heat issue out of the picture for now.
