Microsoft will stop supporting weak encryption methods for sending and receiving emails through Exchange Online starting in July. The company announced the change on Tuesday, warning that outdated encryption protocols will no longer be allowed.
The move affects businesses and organizations still using older encryption standards such as TLS 1.0 and TLS 1.1. These protocols have been deemed insecure due to vulnerabilities that could expose sensitive communications to interception. Microsoft stated that blocking these methods will improve security for all users by reducing the risk of data breaches.
Exchange Online customers have until July to update their systems. After the deadline, emails sent or received using weak encryption will be rejected. Microsoft has provided guidelines for transitioning to stronger encryption protocols like TLS 1.2 or TLS 1.3, which are widely supported and meet current security requirements.
The decision follows industry-wide efforts to phase out outdated encryption standards. Major tech companies have been tightening security measures to combat rising cyber threats. Microsoft’s move aligns with similar actions taken by Google and Apple in recent years.
Affected users should check their email server configurations to ensure compliance. Microsoft will notify administrators about the changes through official channels. Failure to comply could result in disrupted email services for organizations still relying on outdated encryption.
