Message Summary

We’re making some changes to improve the security of your tenant. We announced in 2019 we would be retiring Basic Authentication for legacy protocols and in early 2021 we announced we would begin to retire Basic Authentication for protocols not being used in tenants.

7 days from today we’re going to turn off Basic Authentication for POP3 protocol in your tenant. Based on our telemetry, no-one is currently using Basic Authentication with that protocol in your tenant and so we expect there to be no impact to you.

We previously communicated this change via Message Center: MC191153 (Sept. ‘19), MC204828 (Feb. ‘20), MC208814 (April ‘20) and MC237741 (Feb. ‘21) and you can always read the latest information about our plans to turn off Basic Authentication here.

We will send another Message Center post when we make the change. You may receive additional notifications if any other protocols could be affected.

How this will affect your organization:

Once this change is made, users in your tenant will be unable to access their Exchange Online mailbox using Basic Authentication and this specific protocol.

What you need to do to prepare:

This is for your awareness only. If you experience any issues, please follow your standard support processes.

Client Feedback

Our greatest reward is satisfaction from a job well done. If you have worked with QuixTec, LLC, we’d love to hear from you about your experience.

Richard is an excellent project manager and educator and has been invaluable as we learn to navigate owning and operating our own business. He helped us to build a beautiful, properly functioning website while keeping costs manageable, alerting us to avoidable pitfalls, and keeping us on task to push through the more difficult phases of branding, site speed, SEO, and many other issues we never could have figured out if not for his guidance. Richard is honest, communicative, detail-oriented, and quick to respond to questions and offer suggestions to improve site performance and enhance our messaging. We have recommended him and his company to others and will continue to do so with enthusiasm. He truly wants the best outcome for his clients and puts in the work to make it happen while being mindful of budget and value-add opportunities. We are grateful for his knowledge, his patience, and the team he has put together. There is no-one we would rather have guiding our tech processes!

"Richard’s www.quixtec.com team is awesome. I highly recommend anyone trying to grow their marketing and sales efforts (in a way that is budget friendly yet massively efficient) Originally I looked into Constant Contact, Mailchimp type services but quickly found that they nickel and dime you for email campaigns, charge thousands for marketing automation features and at the end of the day you have no ownership of the toolset. QuixTec was quite efficient at setting up my cloud toolset. Richard personally helped me daily and allowed me to drive when possible as this helps me learn long term. Getting the first email template built was a breeze with their hands-on guidance. They walked me through every step of building and kicking off our first automated campaign. Within 1-2 days I was seeing site visits and contact form submissions leading to immediate sales. I now own a very extensive toolkit in emailing and market automation and I know how to use it."

We were given a very hard task of completing a real estate project management and real estate asset management data base technology platforms and QuixTec has delivered on time, under budget with great results. I highly recommend and endorse QuixTec for all your technology needs. They’re the best!

Vahak Agojian World Vision International

When the idea for our business first came about, researching and finding out the many faces of owning and operating a business were a given. The most difficult and terrifying—yes, for me, terrifying, aspect was the one of Technology. Not just Technology, but everyyything that goes with that term! Building a website delayed the dream, because my insecurity about how to even begin, was overwhelming at the time. Many options were available, and we decided on Richard, because of his knowledge in all applications of the technical side, he knew the lingo required and where it needed to be, his connections and background, his patience and common sense. We are, thanks to Richard and his expertise, fully functional and integrated for where we need to be at this point in our business, confidently knowing that the “Technical” side of things show well, provide an easy experience for our customers, and as we grow, Richard is several steps ahead of us on how to apply what’s needed next. Thank you, Richard Quatier, for all you have done for us to take the worry out of this part of running a business!
