Deprecation of basic authentication for Exchange Online and Gmail

Sonja_Bauernfeind — Wed, 25 Feb 2026 12:44:09 GMT

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 Both companies consider Basic authentication as an outdated industry standard, and thus they are suggesting its customer move to OAuth 2.0 token-based authorization.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.

Hi @Sonja_Bauernfeind got IT to enable basic auth for now.

Why is this taking so long to investigate, the Dynamics/Sharepoint/Outlook365 are already using Oauth2

On the date this post was created OAuth2 support for IMAP/SMTP and POP has been available for over 2 years.

@p_verkooijen I saw your post and I've reached out to our NPrinting R&D to get more details on why this not yet been implemented, I'll post here when I hear back from them thanks!

Hi @David_Friend,

My issues are referring to the Webconnectors. NPrinting could have issues using the SMTP with basic auth.

Is there any update about Oauth for SMTP ?

Re: Deprecation of basic authentication for Exchange Online and Gmail

Sonja_Bauernfeind — Thu, 01 Jun 2023 08:55:12 GMT

Hello @Bryan0605

I would recommend logging an idea in our ideation forum to give this more visiblity.

One exists for Qlik Cloud, which you can vote on already: oAuth authentication for SMTP on SaaS

All the best,
Sonja

Hi, any updates ?

Re: Deprecation of basic authentication for Exchange Online and Gmail

Sonja_Bauernfeind — Thu, 01 Jun 2023 08:54:56 GMT

As of right now, this statement would still be accurate:

Qlik follows Google's and Microsoft's recommendations not to use their services for bulk emailing.

We've put together two articles covering two services:

How to use Sendgrid bulk email service SMTP with Qlik Cloud Services and Qlik Application Automation
How to use Mailchimp bulk email service SMTP with Qlik Cloud Services and Qlik Application Automation

The idea mentioned above is still open, I would suggest reviewing if you can give it more priority on your end using our new idea portal: oAuth authentication for SMTP on SaaS

All the best,
Sonja

We have been dealing with a crippled Qlik Tenant since we moved to Cloud over a year ago.

Should we move back to on-premise to get back these features?

@Sonja_Bauernfeind - Individual alerts set up by users are not bulk emailing. We need to the ability to use OAuth2 with Office365 email for subscriptions and alerting. Every other web based software we use has OAuth2 ability to email on our office 365. There have been zero problems with restrictive rate limiting.

Hello @SDT

Please let our Product Team know by voting on the currently active idea and leaving a comment where you can. What you sent me here is valuable feedback! I'll also be forwarding this internally of course, but the most effective method is the idea.

Any update on OAuth2?

Re: Deprecation of basic authentication for Exchange Online and Gmail

SDT — Fri, 16 Feb 2024 19:21:24 GMT

I asked the same question of Brendan Grady at a training session a few months back.

Still not Oath2. Makes all subscription services non-existent and useless to our company.

Our contract is up this fall and we need to consider other options.

@Sonja_Bauernfeind - Any update?

Re: Deprecation of basic authentication for Exchange Online and Gmail

junpei_liang — Fri, 16 Feb 2024 19:46:25 GMT

@SDT

I completely agree; we cannot risk our company's security by using basic authentication, especially for reports that might contain sensitive data.

Re: Deprecation of basic authentication for Exchange Online and Gmail

David_Friend — Fri, 16 Feb 2024 20:30:51 GMT

I'll ask our R&D team if they have any update on this (they are in Italy so don't expect a reply today though)

@Ruggero_Piccoli any comment on this is welcome!

@David_Friend At the moment (February 2024) Qlik NPrinting supports only basic authentication. I think it need to be managed as a new feature request.

GMail has a rate limitation about bulk email delivering also before removing the support for the simple authentication, as anti-spam rule, so it was not useful to deliver Qlik NPrinting reports. At least the free version of the Google SMTP server.
