Good afternoon,

Please be aware that on June 30, 2021 Microsoft Azure Active Directory (Azure AD) will stop supporting the following Transport Layer Security (TLS) protocols and ciphers:

• TLS 1.0
• TLS 1.1
• 3DES cipher suite (TLS_RSA_WITH_3DES_EDE_CBC_SHA)

As of this date, applications that are communicating or authenticating against Azure AD may not work as expected if they are not able to use TLS 1.2 to communicate.

EASI is currently upgrading Azure AD Connect to the latest version to mitigate any adverse impacts due to this retirement: we will activate the new version of Azure AD Connect at 6 p.m. on Friday, June 18. This action will initiate a full export job that is expected to run for one to three days.

Please note that no new changes will be synchronized to Azure AD until after the full export job has been completed. This includes new user accounts, new shared mailboxes, license changes, UTORmail migrations and name changes. EASI will provide status updates on the ITS System Status page.

We thank you for your patience during the scheduled upgrade. This change will contribute to the overall security of the University’s tenant and will help to ensure its compliance with industry standards.

Please contact Ian Thomas at ian.thomas@utoronto.ca with additional questions.

Kind regards,

EASI Communications
