It’s that time again - Summer has bloomed for our northern hemisphere neighbours, and so have the latest Salesforce updates! We’ve dug through the Summer ‘26 release notes and handpicked the most exciting features for business users and admins.

Check out our latest blog, where we break down the highlights and what they mean for you! Keep reading below for the Enforced Updates.

Enforced Updates in Salesforce Summer ‘26

The following items may impact some clients. For those who are impacted, please check the date by which they will need to be reviewed and rectified. Enrite recommends creating a sandbox to enable the relevant changes and performing the necessary regression tests

Verify Your Email Domain Ownership

What’s Changing?

Salesforce now requires verification of email-sending domains used within Salesforce. Emails sent from unverified domains may no longer be delivered, even if the email address itself has already been verified.

What Does This Mean?
This change may affect automated emails, notifications, workflows, and organisation-wide email addresses that are sent from your company domain. Without proper domain verification, Salesforce could block outbound emails from those domains.

Recommended Actions:

  • Review domains used for Salesforce email sending
  • Verify domains and subdomains using DKIM
  • Check automated emails and organisation-wide email addresses

➡️ For technical details, see this link.

MFA Enforcement for All Employee Users

What's Changing?
Salesforce is enforcing MFA for all employee logins across production and sandbox orgs, including direct logins and Single Sign-On (SSO).

What Does This Mean?

Employees who do not already use MFA may be prompted to register a supported verification method when logging in. Organisations using SSO should also confirm that MFA signals are correctly passed to Salesforce.

Recommended Actions:

  • Review current MFA adoption across users
  • Confirm SSO configurations support MFA requirements
  • Encourage users to register MFA methods before enforcement

➡️ For technical details, see this link.

Phishing-Resistant MFA Enforcement for Privileged Users including Admins

Who is affected?
This applies to users with elevated access, including:

  • System Administrators
  • Users with permissions such as Modify All Data, View All Data, Customize Application, or Author Apex

What's changing?
Standard authenticator apps (such as Salesforce Authenticator and similar MFA apps) will no longer be sufficient for affected users. 

Affected users must use a phishing-resistant login method, such as:

  • Built-in authenticators (e.g. Windows Hello or Touch ID)
  • Security keys
  • Passkeys

These provide stronger protection against phishing and account compromise.

Enforcement dates:

  • Sandboxes: Starting June 22, 2026, staggered over approximately 7 days
  • Production: Starting July 1, 2026, staggered over approximately 30 days

What you need to do:
We strongly recommend reviewing this now to avoid login disruption.

Key actions:

  • Identify users with elevated access
  • Confirm they have an approved phishing-resistant login method available
  • Communicate these upcoming changes to affected users and encourage early registration
  • Complete setup and testing before the enforcement dates

➡️ For technical details, see this link.

Important Salesforce and Platform Update

These updates are worth being aware of as they may relate to your current Salesforce setup or connected applications. 

Chatter Is Turned Off by Default in New Orgs

What's Changing?
Chatter will be turned off by default in Salesforce orgs created from Summer ’26 onward. Existing orgs are not affected by this change.

What Does This Mean?
This change mainly impacts new Salesforce orgs. If your organisation relies on Chatter functionality (such as Case Feed, Experience Cloud communities, or APIs), you may need to enable it manually in Setup. Existing implementations will continue to work as normal.

Salesforce is also continuing to evolve collaboration tools, with Salesforce Channels and Slack becoming the preferred options for internal collaboration in Lightning Experience.

Recommended Actions:

  • Review whether your organisation uses Chatter-dependent features
  • Enable Chatter in Setup if required for your use case (no action needed for existing orgs)
  • Consider Salesforce Channels and Slack for modern collaboration use cases

➡️ For technical details, see this link.

Payments2Us Security Update 

What's Changing?
Salesforce recently enforced new security requirements for all AppExchange applications, including the implementation of PKCE and Refresh Token Rotation (RTR) for Connected Apps.

As part of this change, Payments2Us released version 11.4 on May 11, 2026, which may have required re-authorisation by your Salesforce Administrator.

What Does This Mean?
If you are using Payments2Us, we recommend confirming that the re-authorisation step has been completed and checking for any payment or authorisation-related issues.

Since this is a Salesforce-wide security directive, it is also worth reviewing any other AppExchange applications used within your organisation to ensure any required updates or actions have been completed.

➡️For technical details, see this link.

Use Your Remaining Budget Strategically 

As EOFY approaches, now is a great time to review your Salesforce environment and make the most of any remaining budget. This can also help avoid unused funds impacting next year’s allocation. It’s a great opportunity to consider pre-purchasing Customer Success hours, which can be used for enhancement projects, support, or even a Salesforce Health Check.

Use these hours to identify areas for improvement and highlight any urgent issues before they become bigger challenges. It’s also a practical way to plan ahead for upcoming projects, enhancements, or support needs while making the most of your available Client Success hours.

As many teams begin planning new initiatives for the new financial year, our project capacity can fill up quickly. Securing your hours early helps ensure your team has the support you need when priorities ramp up.
