As part of this Feature Wave you will now be able to use an Authentication Certificate for your Authentication Method when using Office 365 SMTP as your email service for outgoing email connectors. This is to help our customers who may have been using SMTP Basic Authentication until now, but will need to transition to a different authentication approach due to Microsoft's impending phasing out of SMTP Basic Authentication support. This option is available when choosing 'Office 365 (SMTP Relay)' or 'Other' as your Email Service.
Office 365 (SMTP Relay)
If you configure your outgoing email connector's Email Service as 'Office 365 (SMTP Relay)', you will be able to chose either 'Authentication Certificate' or 'None' as your Authentication Method.
Choosing 'Authentication Certificate' for Authentication with SMTP Service
If you chose the Authentication Certificate option, you will be presented with a file box where you can either drag and drop your .pfx file, or browse your files for it. Additionally there will also be a Certification Password box to add your connector's Certificate Password.
Options when choosing 'Other' as Email Service
If you configure your outgoing email connector to use 'Other' as its Email Service, you will be able to chose from None, Username and Password or Authentication Certificate as your Authentication Method.
Choosing 'Username & Password' for Authentication with 'Other' Service
If you choose Username and Password as your Authentication Method, you will be required to fill out your Connector's Username and you Connector's Password.
Choosing 'Authentication Certificate' for Authentication with 'Other' Service
If you choose the Authentication Certificate option, you will be presented with a file box where you can either drag and drop your .pfx file, or browse your files for it. Additionally, there will also be a Certification Password box where you will be able to configure your connector's configuration password.
