Google and Microsoft deprecated basic authentication for their email services in 2022. Both companies consider Basic authentication as an outdated industry standard, and thus they are suggesting its customer move to OAuth 2.0 token-based authorization.
On May 7, 2024, we introduced OAuth2 authentication for the Microsoft 365 email provider
What has changed?
Microsoft – Outlook: Starting on October 1, 2022, Basic authentication was disabled for Outlook, EWS, RPS, POP, IMAP, and EAS protocols in Exchange Online. SMTP Auth will be an exception and will only be disabled if it is not being used, when it comes to new tenants it will be a configurable parameter disabled by default. Meaning that applications that already use SMTP Auth won’t be affected by these changes and users who want to keep using SMTP Auth will be able to do it. (Source)
Google – Gmail: Starting with May 30, 2022, Google no longer supports Basic authentication and “Less secure app access” option will disappear from the google account management console if it’s not being used. (Source)
What are Qlik's plans for the future?
Both Google and Microsoft have restrictive rate limits in play for their cloud services.
For that reason, Qlik recommends using a bulk e-mail service such as Sendgrid, Mailchimp, or Mailgun. These services provide purpose-built solutions to handle the volume alerting and reporting solutions produce.
On May 7, 2024, we introduced OAuth2 authentication for the Microsoft 365 email provider. Keep Microsoft's API limits in mind before choosing your email provider. This includes requests per minute, concurrent requests, and size restrictions. Example: a capability such as Tabular Reporting can create large files as part of its reporting job creation, which may exceed Microsoft's service limits.
Qlik is currently investigating OAuth2 as an authorization scheme for SMTP from bulk mail solutions.
