*Deleted due to 22 months of ineffectual responses*

[paradoxblu]

22 months after my post, I continue to receive notifications from developers advertising their tech tools and having big feelings when I point out that their reply is inherently not applicable.
For MONTHS I have requested admins delete my OP.

I was facing a similar issue and then I finally found out BitRecover Gmail Backup Software. I easily exported all the gmail emails to individual pdfs. You just need to download the tool, login with your Gmail id, select the folder and, pick PDF as the saving option. Then export it.

thank you, however I explicitly named in my post "I prefer to not download 3rd party software, as the email content itself is sensitive." therefore this solution will not work.

Slight modification to @JR Boulay's suggestion: That's Outlook Classic. You'll find a link for it in Outlook 365's settings.

If you looking in Office 365: Basic, it's a little too basic to have included the tool. 

[paradoxblu]

The entire point of my post was to NOT use 3rd party software of any kind due to the sensitivity of the content

[JR Boulay]

Are you serious?

You don't want to use third-party software because you want to archive sensitive content that is on Gmail.
Are you really unaware that Google has already read and processed all the information contained in your emails?

[paradoxblu]

@JR Boulay it sounds like you're feeling disappointed in yourself and other replies for not having actually read the OP before posting That's on you, little buddy.

@paradoxblu That's a foolish and immature reply. @JR Boulay brought up a valid point about Google having access to all your content. Microsoft and Google look at your browsing, not your emails, to show you ads. Emails are bot-scanned for spam, viruses, and illegal content dealing with children. Unless you have your own server set up with a custom domain, none of. your data is private from a malicious user.

@Dave Creamer of IDEAS so, you didn't read my [nearly 2-year old] OP nor any of the numerous other ineffectual commnents and are now having big feelings about me pointing out your addition to that canon while you come here to explicitly advertise an unregistered product (yours?) that is clearly contraindicated for the purpose? 
I said what I said. 

[JR Boulay]

Sensitive content on Gmail... I laughed for at least 10 minutes, but I remained polite to you.

You should read this, especially the Gmail chapter: https://digitalcontentnext.org/wp-content/uploads/2018/08/DCN-Google-Data-Collection-Paper.pdf

When someone posts on Adobe's Acrobat forum, we assume they have Acrobat and trust it.

If you don't like the answers from Adobe experts who are trying to help you and get you thinking, I suggest you ask your questions to the experts on Facebook. They know everything.

Presumedly, since you use Gmail, you can use Chrome.

@Dave Creamer of IDEAS again: no 3rd party software. See OP.

[Dave Creamer of IDEAS]

Your OP said you _prefer_ not to use 3rd-party software, not to avoid it at all costs. 

[paradoxblu]

@Dave Creamer of IDEAS congratulations. Next time please review the prior responses if you're uncertain about advertising on someone's post.

[Dave Creamer of IDEAS]

I did, thank you. 

So your options remain do it one-at-a-time, use Outlook, or use a third-party utility. 

Not that I care, but I don't understand why you trust Google so much but have a problem with Microsoft. Outlook "reports" home for subscription status, like Adobe, the stand-alone program does not "read" the emails. 

Good luck.

BTW, one of your earlier posts (not this thread) mentions you use a Mac. The Outlook option won't work there.
