What's new in version 42?

Pexip Infinity now supports Microsoft Graph API for Secure Scheduler for Exchange when connecting to Microsoft 365 Exchange Online.

Microsoft has announced that Exchange Web Services (EWS) for Exchange Online will be deprecated on 1 October 2026 (although an extension is available). Customers using Exchange Online must migrate their Secure Scheduler for Exchange integrations to Microsoft Graph before this date. Exchange Server on-premises deployments continue to support EWS.

This release introduces:

• Microsoft Graph as an Exchange API type for Secure Scheduler for Exchange.

• OAuth authentication using either client secrets or private keys and certificates.

• Microsoft Graph configuration fields for Exchange integrations.

• An alarm that identifies Exchange Online integrations still using EWS.

Existing Exchange integrations continue to use EWS after upgrading because EWS remains the default Exchange API type.

Microsoft Teams audio

• Audio prompts and transfer delay: Audio prompts are now played to participants before they are moved to a breakout room and before they are moved back to the main room. A configurable transfer delay can also be applied to give participants time to hear the prompt before the transfer takes place.

• Meeting name: When a participant is in a meeting with breakout rooms enabled, the name of the meeting is now displayed in addition to the name of the breakout room they are in.

Google Meet interoperability: watermark support

• Enabling Exchange Scheduler with personal VMRs

• Using Identity Providers

• Configuring Pexip Infinity for Exchange Scheduler

• You can now filter the events sent to an event sink.

• Events relating to transcription (live captions and event sink transcripts) are now available.

You can now configure Virtual Meeting Rooms and Virtual Auditoriums to send transcripts of the meeting audio to an event sink.

This feature requires integration with Pexip's AI Media Server.

You can now use participant policy to set the live captions language for an individual participant.

Registering your app

Registering devices to Pexip Infinity

When entering a Video address, users are offered suggestions based on their recent calls, favorite addresses, and (if they are registered) a search of the organization's directory.

Users can select the addresses to add to their list of Favorites.

Administrators can use customization to enable and disable Recents and Favorites, and pre-populate the Favorites list.

Blurring or replacing your background

Users can select whether they are prompted to enter their display name each time they join a meeting that requires it, or whether their saved name will be used instead.

Administrators can use customization to set whether this option is enabled or disabled by default.

Participants who are able to receive direct chat messages are more clearly distinguished from those who cannot.

Body of the custom step

sandboxValues

The data-testid (referenced when hiding elements from the web interface) has changed for the following element:

• The single button to blur the background (button-background-effect-blur) has been replaced by two new buttons (button-background-effect-blur-low and button-background-effect-blur-high).

Secure Scheduler for Exchange

• Automatic meeting recovery: The scheduling recovery script has been removed. Scheduled conferences are now recovered automatically by the scheduling service after management node recovery.

• Removed scheduling template variables: The deprecated {{start_time}} and {{end_time}} template variables have been removed. Exchange integrations that still use these variables must be updated before they can be saved.

• Removed OAuth delegate authentication: The OAuth (Delegate access with a service account) authentication method has been removed for Secure Scheduler for Exchange Exchange integration. Existing integrations must be updated before they can be saved.

• Scheduling maintenance changes: The scheduling maintenance script has been removed. Microsoft Exchange retention policies should now be used to manage mailbox cleanup.

Removed OAuth delegate authentication: The OAuth (Delegate access with a service account) authentication method has been removed for One-Touch Join Exchange integration. Existing integrations must be updated before they can be saved.

Hybrid key exchange is now available on all services

In addition to classical key exchange algorithms, hybrid key exchanges algorithms are now enabled on all services by default (and cannot be disabled).

Deployments running in FIPS compliance mode

Pexip Infinity v42 and later running with FIPS cryptography enabled does not support hybrid key-exchange algorithms.

Google Meet prevents disruption in meetings with more than 5 participants by automatically muting any additional participants on join. Previously Pexip Infinity did not reflect this behavior; from v42, VTC participants in a gateway call to a Google Meet meeting are automatically muted if at least 5 participants are already in the meeting. When VTC participants are automatically muted, they must actively unmute in order to be heard.

• Microsoft Teams domain change: In Q1 2026 Microsoft will start transitioning Teams links from teams.microsoft.com to teams.cloud.microsoft. One-Touch Join will automatically support invitations using teams.cloud.microsoft after upgrading to v39 or later, but if you use any custom rules that use teams.microsoft.com, you must update them manually to use the new format.

• Migrate to RBAC for the Graph API: Microsoft have replaced Application Access Policies with Role Based Access Control (RBAC) for Apps. We recommend that you switch from App Access Policies to RBAC. See the Microsoft's page for more information.

Certificate-based authentication (CBA) is now the default method to authenticate the Teams Connector CVI application towards MS Graph. You can still use the previous password-based authentication method, but we plan to deprecate it in a future release, thus we recommend using CBA for new installations, or migrating to CBA as soon as practicable when upgrading existing deployments.
