Azure File Sync is removing support for TLS 1.0 and 1.1 in August 2020
Published date: May 11, 2020
Azure File Sync service will remove support for transport layer security (TLS) 1.0 and 1.1 in August 2020. All supported Azure File Sync agent versions already use TLS 1.2 by default. If you're not using TLS 1.2, this would most likely be because TLS 1.2 is disabled on your server or (more likely) a proxy is being used.
To see the TLS settings on your server, view the registry settings. If you're using a proxy, please consult its documentation and ensure it's configured to use TLS 1.2. Azure File Sync service regions added after May 1, 2020, will only support TLS 1.2 and we'll remove TLS 1.0 and 1.1 support from existing regions in August 2020.
