While it is likely that Office 365 will need to leave TLS 1.0 enabled broadly for the near future, we are rolling out TLS 1.2 by default which will allow us to publish updated guidance for Exchange on-premises. Please stay tuned to EHLO blog for further updates — several configuration changes will be necessary to ensure everything works smoothly.

we are facing similar issue, TMG/ADFS with TLS 1.0 off - producing 503 error during autodiscover. Microsoft told us this is an expected behavior and they working on fix however PCI compliance is chasing us up to switch off TLS 1.0.Stefan supported this idea ·
