End of support for Basic Authentication access

Hello,

We have Appian 18.1 Version. As Microsoft  is ending support for Basic Authentication which will not support IMAPS anymore as protocol, is there a workaround or documentation to change below configuration for "IMAPS"

# Defines settings for a poller that will monitor an inbox and route messages based on the alias rules
conf.mailhandler.poller.EmailHandlerBean.mailServer=outlook.office365.com
conf.mailhandler.poller.EmailHandlerBean.mailFolder=INBOX
conf.mailhandler.poller.EmailHandlerBean.storeProtocol=imaps
conf.mailhandler.poller.EmailHandlerBean.port=993
conf.mailhandler.poller.EmailHandlerBean.starttls=true
conf.mailhandler.poller.EmailHandlerBean.userName=*************
conf.mailhandler.poller.EmailHandlerBean.pollingInterval=300000
conf.mailhandler.poller.EmailHandlerBean.partialFetch=true
conf.mailhandler.poller.EmailHandlerBean.forceImapLogin=false
