Dear Experts, can you please suggest us 2 problems:

1. How can we reset multiple Gmail accounts at the same time? (We are using Gsuite, and are Admin accounts)

2. How can we configure multiple MS Outlook accounts at the same time on Window OS?

Many thanks!

Clarify what you mean by reset. If you're talking about password reset, you just login to GSuite + follow the reset directions.

For configuring any accounts on Outlook, you follow the normal Outlook setup instructions.

Unsure what your asking. It seems like you're asking someone to read all the normal docs for you + somehow republish an abbreviated version.

Best open two separate questions to replace this question + begin going through docs executing the related command sequence.

When you hit a specific problem, where the docs fail, report what docs you used + what you expected to happen + what really happened.

Likely providing this level of detail will allow someone to answer you quickly.

No, I am asking the scripts (or tools) which we can use to reset 1000 gmail accounts simultaneously.

Also we are finding a way to configure all these accounts on MS Outlook, so that all Gmail data can be downloaded from Gmail. We are going to end the contract with Google - that is the main reason :)

Regards your reset question.

Clarify exactly what you mean by reset.

Are you saying you requires resetting 1000 gmail account passwords simultaneously?

Regards your Outlook configuration question.

So what you're really looking for is a way to scrape all Gmail data into some other mail system.

Which may be why you'd like to reset all passwords (if that's what you're really asking) in your previous question.

So... If I'm guessing correctly, you'd like to...

1) Reset 1000s of gmail address passwords to one password, so you have a known way to access all mailboxes.

2) Then download all mail from all mailboxes into some other mail system.

3) Destroy all Gmail addresses.

Let me know if I'm correct. Yes/No?

Yes, you are correct.

We will reset 1000 gmail accounts' passwords (1000 different ones), then configure MS Outlook for them, take all the data from Google then destroy the contract.

We will move to Exchange on-premise.

Ah... Now your questions make sense...

About mass password resetting.

This is the really tough one. Google goes to great lengths to ensure only browsers connect to Gmail, so you have to first develop a tool to do this.

http://phantomjs.org/examples provides a good starting point.

Caveat: If Google catches you trying to access GMail using a tool rather than a browser, they first start by sending a CAPTCHA down the pipe + if some number of CAPTCHA responses are missed, they block your IP. Very ugly.

If a client hired me to code this, I'd start with cheap, throw away VPS instances + each time Google blocked the IP, get another VPS + keep working...

There's no tool I know of which will do this out of the box.

*Mass email migration.*

This is a bit tricky too, because this requires logging into each Gmail account + enabling access of the account via IMAP.

Then you just use one of the many site:github.com imap syncsite:github.com imap sync projects to sync your mail.

Once you have the code constructed for password resetting, where Google is fooled into thinking you're using a browser, I'd extend this tool to auto-enable IMAP for each account.

If I were doing this, I'd use some non-Chrome UA (user agent string), like Opera or https://ghostbrowser.com to attempt circumvention of Google using browser fingerprinting. You figure Google knows more about fingerprinting Chrome than other browsers, so using a non-Chrome UA may produce faster development.

Now... All this said, if you have budget available, you might just hire some humans to go through + do this process manually.

1000s of mailboxes may seem like a lot + paying development for a tool smart enough to outsmart Google... will be expensive...

And... once your tool is working, you'll still only be able to change one unique account from one unique IP every few hours.

So even with a tool, you have to run the tool as a human would run a browser. If you try to change 1000s of Gmail accounts from 1 IP, Google will surely block your IP.

Likely the cheapest + fastest + more fool proof solution, will be hiring people to do this manually.

Interesting question.

Why not following the official way?

Google will not stop you.

Move G Suite data to another service provider

Oops... I missed that all your Gmail accounts are running under GSuite.

Jackie's correct. Use the official method.
