Product activation

Please see the announcement on the Home Page, copied below.


As of April 30th 2019 our service provider for authentication of installations (aka activation) is withdrawing their service. We have reviewed the impact of their decision on our modest offering and feel we have no choice but to withdraw OTA from the market. This decision is taken with regret and has been informed by the age of the product and the tools it uses (though it still works well for current users). 

Current users have come to rely on the results produced by OTA and we plan to offer a version of the software to them without activation limits, on the basis that this last edition is used by them only and will work but will not be supported in the future.

We are saddened to “step off the stage” but this decision has been thrust upon us and we ask for your understanding.

Product activation for Outlook True Archive [OTA]

What is Product Activation?

Product Activation is a software feature that scans a computer, computes a fingerprint for its hardware, and links a specific product such as Outlook True Archive with the fingerprint.

What information is passed during the Activation Process?

The information transmitted does not include any personal information, nor does it include any information about the software or documents that reside on the computer. Only your Outlook True Archive serial number and the hardware fingerprint are transmitted.

What happens if I change the hardware in the computer?

Minor changes to the computer’s configuration will not affect the activation. Major changes to the computer’s configuration may require reactivation of the software. If you are about to make hardware changes to your computer you should first deactivate Outlook True Archive by un-installing the software. (for very old versions, see “How do I manually release / deactivate the Outlook True Archive license?” below).

How many times can I re-install Outlook True Archive?

You can reinstall Outlook True Archive up to four times.

(However, for very old versions of Outlook True Archive, you must first deactivate your Outlook True Archive license by following the steps outlined in How do I manually release / deactivate the Outlook True Archive license?” shown below.)
