Advance warning - Turning off Basic Authentication for Exchange
Posted: Wed 7 Dec 2022, 10:59am.
At the end of this year Microsoft are depreciating Basic Authentication protocols for Outlook, Exchange Web Services (EWS), Remote PowerShell (RPS), POP, IMAP, and Exchange ActiveSync (EAS). Customers using older client applications to connect to Sussex Email that is still using Basic Auth must update them to continue to access Email Services. This change will ensure that everyone is connecting to our Exchange service using modern authentication methods, to help better protect our internal systems, identities and internal.
We will be turning off Basic Authentication for Exchange at 8am Monday 12th December.
If you are using an email client that doesn’t support modern authentication then you will stop receiving and being able to send emails from this date.
In preparation:
Please make sure that all your devices and Outlook are up-to-date.
Although we only recommend you use Outlook to connect to university email the following clients should be able to support modern authentication methods. You will need to ensure your device is updated to use one of the following:
- Outlook 2016 or later
- Outlook 2016 for Mac or later
- Outlook for iOS and Android
- AppleMail for Mac OS 10.14 or later
- AppleMail fo iOS/iPadOS 15.6 or later (earlier versions may have a work around /its/help/faq?faqid=2957)
- Windows Mail (Windows 10)
