Microsoft Office 365 to retire basic auth support for IMAP/POP
In the second half of 2021, Microsoft will end support for basic authentication for several protocols to access Exchange Online; including the IMAP/POP3 protocols used by Pega's email listener (See Microsoft announcement here).
Impact on you:
Pega email listeners using Office365 will not be able to authenticate to Exchange Online accounts once support is discontinued.
Please note: this change will only impact email listeners using Office365/Exchange Online accounts. There is no impact on clients using any other email provider (including Microsoft Exchange on-prem), and no impact on outgoing email capabilities.
For Pega 8.4 customers using email listeners to authenticate to Exchange Online: Update any email account record that connects to an Office365 account to leverage the native MS Graph based configuration, and not IMAP or POP3. Please see this article for more details on how to configure Microsoft Graph based configuration in the email listener.
For customers using Pega email listener on Pega versions prior to 8.4: Please contact your account executive so we can support you in your upgrade.
