If you collect your emails using Microsoft 365 then you should have received an email from us recently about this upcoming Saturday 1st October 2022.
That’s the date that Microsoft will remove support for Basic Authentication and require all connections to use Modern Authentication instead.
It means that if you access your emails using an old device or app, then you may find yourself unable to do so after Saturday. You may also run into problems if you collect your emails using a POP3 account, rather than an Exchange account.
Outlook users
Outlook Online at https://login.microsoftonline.com already uses Modern Authentication, so if you access your emails there via your web browser, then you can continue to do so after Saturday.
If you have Outlook installed on your computer, then you need to be aware that the oldest version that supports Modern Authentication is Outlook 2013. If you are using an earlier version than that then you will almost certainly have problems after Saturday.
Even if you are using Outlook 2013 or higher, unless your account is configured as Exchange, then you may also encounter problems.
A quick way to tell whether you’ll be affected is to hold down the CTRL key on your keyboard and then right click on the Outlook icon in your system tray (bottom right corner) whilst Outlook is running.
Left click on the Connection Status option and, in the pop-up window that appears, look for the Authn column. If it says Clear then you are using Basic Authentication, whereas if it says Bearer then you are using Modern Authentication.
iPhone/Mac users
iOS 11 or later, iPadOS 13.1 or later and macOS 10.14 or later all support Modern Authentication, so long as you are using the Outlook app and are configured as Exchange. If you are using another app to collect your emails, or you have an older version than the ones listed above, then you may run into problems accessing your emails from Saturday 1st October 2022.
