Overall, what’s the best way to deal with these changes? What to do nowįirst, determine whether you will be affected. (You can see examples of this by scrolling on several blogs here and here that showcase the older basic authentication connection.) If so, you’re still using basic authentication.Īnother way to see what you’re using is to look at the authentication graphic offered up to you. (Many providers have already moved to different platforms.) How do you know if you are still using basic authentication? That’s actually easy to determine: check your email settings to see whether they show you’re using POP3 or IMAP as your mail server protocols. Many Internet Service Providers use Microsoft 365 as their rebranded mail platform, and many other ISPs are following suit because basic authentication exposes mail servers to hacking. If you’re an individual user not running Microsoft 365 as your mail platform, you still may be affected by the coming changes. That way, you can easily set up older devices to still use email without lowering the security of your Microsoft 365 implementation. If you rely on legacy protocols from all sorts of devices, it can often be easier to use a third-party solution such as it allows you to set up a static IP address that is allowed to email.
(Legacy clients and devices will need to be configured to submit using the new endpoint to connect.) Set the AllowLegacyTLSClients parameter on the Set-TransportConfig cmdlet to True. To take advantage of this new endpoint, admins will have to: In addition, as Microsoft notes in its blog post, there will still be an opt-in endpoint to allow SMTP AUTH clients to authenticate using legacy TLS for devices. Set-CASMailbox -Identity -SmtpClientAuthenticationDisabled $False To enable SMTP auth for specific mailbox: Set-TransportConfig -SmtpClientAuthenticationDisabled $True To enable it tenant-wide on your account, go into Exchange PowerShell: If, by chance, you find SMTP AUTH isn’t working after the October 2022 change is rolled out, you can re-enable it with the following cmdlet. If you use Microsoft 365 and rely on SMTP AUTH to connect your scanners, this should continue to work.
This is typically used in businesses to connect devices such as printers and copiers so that they can send out scanned documents. Note: the new changes will not impact SMTP auth. In the last 10 years, Internet Message Access Protocol (IMAP) has risen the forefront, though POP3 remains in use. It was designed at a time when mail server operators wanted users to get emails off their servers to save space. Once the emails are downloaded, you can opt to leave copies on the server or delete them. It was designed to support offloading emails from the mail server to a local email client. Originally described in 1984 in RFC 918, it was followed by POP2 in 1985 in RFC 937.
POP3 is one of the oldest mail protocols around. (If you have an easy-to-crack password, an attacker can use dictionary attacks to eventually guess your password.) The ins and outs of POP3 and IMAP As long as those mail servers have to support these older protocols, attackers can use any number of brute force attacks and other devious methods to break into your mailbox. You might think POP access using basic authentication should be secure enough, assuming you don’t click on malicious links, do keep your computer up to date, and use a secure browser.Īs it turns out, attackers can use weaknesses built into this older protocol to break into online mail servers.
Microsoft secure email service password#
So just what is basic authentication? It’s what we’re used to already - access by username and password to old-fashioned Post Office Protocol or “pop” email, where you log in and download emails to your computer. It had planned to disable authentication earlier this year before realizing it couldn’t do so without impacting businesses and users still struggling amid the pandemic. This isn’t the first time the company has warned us about this. 1, 2022, Microsoft will be disabling basic authentication for its online mail services. A second change scheduled for next year may have a bigger impact on how you connect your email client - and may affect other email apps, too.īecause it could affect many users and businesses, Microsoft is giving everyone fair warning - a year in advance. 1 - it’s important to remember this isn’t the only change coming for Outlook. With Microsoft about to shut off some versions of Outlook from access to Microsoft 365 and Outlook 365 services - that happens Nov.
