Sunsetting and Retirement of Affixa

16 January 2026: Today, we’ve made the difficult decision to begin sunsetting Affixa from 1 February 2026 and retire it on 31 January 2027.

Affixa has played an important part of people’s business workflows for the last 17 years, however the IT landscape has now substantially moved on. Microsoft has threatened to retire the email subsystem in Windows that Affixa relies upon for over 8 years.

Our company has always been a small, family-run business, and due to changes in our lives and circumstances over the years, it’s also become harder and harder to dedicate the time to Affixa.

The natural decline in demand for Affixa, and the reduction in our available time to nurture the product, have led us to make the sad decision to sunset and eventually retire it.

We’re enormously grateful for your support over the last 17 years. Thanks for trusting our software and our people in helping you achieve your goals.


Our recommendation is that you use the upcoming period to identify alternative email workflows and be ready for the software’s retirement.


What do you mean by “sunsetting”?

From 1 February 2026, we will pro-rate subscriptions and renewals so they go no further than 31 January 2027.

As we get closer to 31 January 2027, we will begin to decline new subscriptions and renewals in some circumstances (see below).

On 31 January 2027, all services will cease.

When is my subscription due for renewal?

If you have a paid subscription, you can find out your expiry (renewal) date in the following ways:

  • In Affixa Desktop (green, circular icon), go to the Options screen and go to the final tab.
  • For Affixa Enterprise (colourful star-like icon), log into the Portal as an Administrator and look at your home screen.
  • Finding your most recent subscription purchase or renewal email from us.

Tell me more about how sunsetting impacts subscriptions and renewals.

  • If your renewal date is before 1 November 2026, you will be able to renew for a period of less than a year which will end on 31 January 2027, at which point the software will cease to be supported.
  • If your renewal date is on or after 1 November 2026 and before 1 January 2027:
    • If your subscription is for 50 users or more, you will be able to renew for a period which will end on 31 January 2027, at which point the software will cease to be supported.
    • If your subscription is for less than 50 users, you will not be able to renew and your service will cease to be supported on your renewal date.
  • If your current renewal date is on or after 1 January 2027, we will not accept your renewal and your service will cease to be supported on that renewal date.

Note that all expiry dates are based on the UTC time zone.

You say “cease to be supported” – but will the software still work?

That depends on whether you’re using Affixa Desktop or Affixa Enterprise when your service ceases. With a subscription to Affixa, you’re entitled to use either product. See the following questions for more detail.

What does this mean for Affixa Enterprise users?

The Affixa Enterprise software has a colourful star-like icon and relies on our servers to operate.

When your subscription ceases, you will find that Affixa will stop creating emails and will state that your subscription has expired. Alternatively, if your subscription ended on 31 January 2027, you may be told that your software cannot contact our servers or believes itself to be offline. You should remove the software from your computers as it will no longer function.

All data held on our servers (including user account data) will be deleted and the Google Workspace integration will be removed on 1 February 2027.

What does this mean for Affixa Desktop users?

Affixa Desktop has a green, circular icon.

As your subscription ends, you will revert to the free usage tier (limited to a single account with no email signatures supported).

The software will continue to work at the free tier until 31 January 2027, but you should expect it to cease working at that date.

The Affixa Desktop free tier is only for personal use; not for organisational use. Where does that leave my business / charity / educational establishment / government agency?

As your subscription ends, we will allow you to use the free Affixa Desktop tier for non-personal use, however it will be unsupported by us and may cease to work at any time.

What about the Chrome or Firefox extensions?

These will be retired on 1 February 2027 from their respective extension stores. These have only ever given value-added enhancements on top of the core products; the extensions by themselves cannot create or send emails.

Affixa is integral to my business workflow and I can find no direct replacement. What should I do?

Your options are to:

  1. Change the workflow itself to not have the dependency on Affixa, wheresoever possible.
  2. Replace Affixa with a desktop email client that supports “Simple MAPI”. One such example is Thunderbird.

  3. Write your own Simple MAPI integration with your email provider (e.g. Gmail). We have a component (Windows DLL) that is a Simple MAPI provider and which will significantly expedite your delivery of an in-house solution. Your replacement software can be written in any desktop programming language.

    Perpetual, royalty-free licences for this component are now available for USD $500. All purchases must be completed by 31 January 2027 and support for that component will also cease on that date. Please use the chat widget in the bottom right of your screen to contact us and discuss this option further.


Note that, according to Microsoft, “the use of Simple MAPI is discouraged. It may be altered or unavailable in subsequent versions of Windows.”

My subscription is due to expire after 31 January 2027

A very small handful of customers have subscriptions which expire later in 2027 or 2028 because we used to offer multi-year subscriptions.

To receive a credit for the period starting 1 February 2027 to your expiry date and a refund, please use the chat widget in the bottom right of your screen to contact us.

Please provide your subscription code and the invoice number from your most recent purchase so that we can confirm your identity. Please also provide bank account details for the account into which you would like to receive the refund (UK details, US ACH details or IBAN details are acceptable).
