Is TLS 1.1 Obsolete?
The Internet Engineering Task Force has formally deprecated the TLS 1.0 and TLS 1.1cryptographic protocols
A security protocol (cryptographic protocol or encryption protocol) is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods, often as sequences of cryptographic primitives.

Is TLS version 1.1 deprecated?
As part of ongoing efforts to modernize platforms, and to improve security and reliability, TLS 1.0 and 1.1 have been deprecated by the Internet Engineering Task Force (IETF) as of March 25, 2021.Is TLS 1.1 still supported?
Support ending for TLS 1.0/1.1 in Teams.Microsoft will no longer support TLS 1.0/1.1 in Microsoft Teams Desktop application starting July 7, 2021. This change will affect Teams third-party extensions, add-ons, and embedded websites that use TLS 1.0/1.1.
Why are TLS 1.0 and 1.1 deprecated?
IETF has formally deprecated the TLS 1.0 and TLS 1.1 cryptographic protocols because they lack support for recommended cryptographic algorithms and mechanisms. The Internet Engineering Task Force (IETF) formally deprecates Transport Layer Security (TLS) versions 1.0 (RFC 2246) and 1.1 (RFC 4346).Is TLS 1.2 still supported?
The TLS 1.2 DeadlineAs previously mentioned, as of the end of 2020, TLS versions 1.0 and 1.1 are no longer supported. That means that websites that don't support TLS 1.2 or higher are now incapable of creating secure connections.
TLS 1.1 is Dead … Well Almost! thanks to Chrome 84 - (Deep Dive Analysis)
Is TLS 1.3 released?
The most recent, TLS 1.3, was released in August 2018.Is TLS 1.2 compromised?
A team of researchers has documented a vulnerability in TLS 1.2 (and earlier versions) that could allow a man-in-the-middle attacker to acquire a shared session key and decrypt SSL/TLS traffic.Is TLS 1.0 vulnerable?
TLS 1.0 has several flaws. An attacker can cause connection failures and they can trigger the use of TLS 1.0 to exploit vulnerabilities like BEAST (Browser Exploit Against SSL/TLS). Websites using TLS 1.0 will be considered non-compliant by PCI after 30 June 2018.Can we use TLS 1.1 in Exchange Online?
We have already begun deprecation of TLS 1.0 and 1.1 as of January 2020. Any clients, devices, or services that connect to Office 365 through TLS 1.0 or 1.1 in our DoD or GCC High instances are unsupported.When was TLS 1.0 and 1.1 deprecation?
As of October 31, 2018, the Transport Layer Security (TLS) 1.0 and 1.1 protocols are deprecated for the Microsoft 365 service.When did TLS 1.1 expire?
Answer: The industry is working to deprecate support for TLS 1.0 and 1.1 this year. Google, Microsoft, Apple, and Mozilla have all announced that their browsers will no longer support TLS 1.0 and 1.1 as of March 2020.When did TLS 1.1 become insecure?
If your web site uses a TLS 1.0 or 1.1 website, as of January 13, 2020 it will display the following warning, and in 2021 Chrome will not load websites with TLS 1.0 or 1.1.Is SMTP going away?
Microsoft is doing its level best to remove SMTP basic authentication from Exchange Online as quickly as possible. Basic auth for SMTP connections will disappear gradually as time goes by.Does Exchange 365 use TLS?
TLS basics for Microsoft 365 and Exchange OnlineExchange Online uses TLS to encrypt the connections between Exchange servers and the connections between Exchange servers and other servers such as your on-premises Exchange servers or your recipients' mail servers.
Does o365 Force TLS?
By default, Microsoft 365 or Office 365 sends mails using TLS encryption, provided that the destination server also supports TLS.Why is TLS 1.0 not used?
Among other weaknesses, TLS 1.0 is vulnerable to man-in-the-middle attacks, risking the integrity and authentication of data sent between a website and a browser. Disabling TLS 1.0 support on your server is sufficient to mitigate this issue.Is TLS 1.1 vulnerable to beast?
Discovering whether your web server is vulnerable to BEAST is very easy. If it supports TLS 1.0 or any version of SSL, it is vulnerable to BEAST.Can TLS 1.0 Be Hacked?
According to our research, more than 30% of web servers still support TLS 1.0, which means that they are susceptible to the BEAST attack.Is TLS 1.3 still experimental?
TLS 1.3 has been extensively tested in experimental browser implementations, and it is now ready to replace TLS 1.2 as the network security protocol of choice. Publishing TLS 1.3 is a big step closer towards a faster and safer Internet for all.Is TLS 1.3 supported in Windows 10?
Microsoft plans on enabling TLS 1.3 by default on all versions of Windows 10 after version 2004. Please note that Microsoft Edge Legacy and Internet Explorer will not support TLS 1.3. You will need to upgrade your browser to Chromium based Edge browser for moving forward with security and enhanced performance.Is TLS 1.3 fully supported?
TLS 1.3 protocol has improved latency over older versions, has several new features, and is currently supported in both Chrome (starting with release 66), Firefox (starting with release 60), and in development for Safari and Edge browsers.Is TLS 1.3 Vulnerable?
Many of the major vulnerabilities in TLS 1.2 had to do with older cryptographic algorithms that were still supported. TLS 1.3 drops support for these vulnerable cryptographic algorithms, and as a result it is less vulnerable to cyber attacks.Is IMAP being phased out?
On October 13th, 2020, Microsoft will stop supporting username & password authentication for the IMAP and POP3 protocols. In layman terms, any email application out there that connects to Microsoft email servers using IMAP or POP3 (Basic Authentication) will stop working.Is Microsoft disabling basic authentication?
Microsoft warned customers today that it will start disabling Basic Authentication in random tenants worldwide on October 1, 2022. This reminder comes after the company's September announcement and after seeing that there are still lots of customers who haven't yet moved their clients and apps to Modern Authentication.Why is IMAP not secure?
IMAP security issuesThe top IMAP security issue is due to the fact that it was designed to accept plaintext login credentials. While this is not the only issue, it is probably the most intransigent challenge to defenders.
