Configuring Pexip Infinity for VMR Scheduling for Exchange

The URL used to connect to Exchange Web Services (EWS) on the Microsoft Exchange server.

• For Office 365 deployments this will be https://outlook.office365.com/EWS/Exchange.asmx
• For Exchange on-prem this will usually be https://<exchange_server>/EWS/Exchange.asmx
  • If you have multiple Exchange servers in your deployment, this can be the URL of EWS on any one of the servers.
  • If you are using a load balancer, this can use the FQDN of the load balancer within the URL (e.g. https://<load_balancer>/EWS/Exchange.asmx).

The username of the service account to be used by this VMR scheduling for Exchange integration.

This is the username you assigned when Creating a service account for Exchange on-premises or Creating a service account for O365.

• For Office365 deployments, the format is usually name@domain.
• If you are using NTLMv2, this must be in the format name@domain.
• For other on-premises deployments, the format may be either domain\name or name@domain, depending on your domain.

A single service account can be used by more than one VMR scheduling for Exchange integration.

Enable this option to authenticate the service account using OAuth 2.0. This option is only supported for Exchange in Office 365. Leave this option disabled to continue using basic authentication. If you select this option, you must sign in to the service account after completing and saving your configuration.

As of October 2022, Microsoft will stop supporting and fully decommission basic authentication for EWS to access Exchange Online (for more information, see Microsoft's announcement). We therefore strongly recommend that for Office 365, all new deployments authenticate the service account using OAuth 2.0, and all existing deployments are updated to enable this option as soon as possible.

Enable this option to authenticate the service account using NTLMv2. This option is only supported for Exchange on-premises. Leave this option disabled to continue using basic authentication.

NTLM Authentication will not work if a Layer 7 load balancer is in use. To work around this issue we recommend reconfiguring your load balancer to Layer 4.

(Available if OAuth for the service account has been enabled)

Enter the Application (client) ID that was generated for you by Azure when you saved the App Registration (see Taking note of configuration).

(Available if OAuth for the service account has been enabled)

Enter the Redirect URI that you used when Enabling OAuth authentication for Office 365.

This must be in the format https://<Management Node Address>/admin/platform/msexchangeconnector/oauth_redirect/.

The OAuth redirect URI is the page on the Administrator interface to which the Pexip Infinity administrator will be returned after they have successfully signed in to the service account. Because it is a page on the Management Node, this URI is internal to your deployment and only needs to be accessible from the administrator's web browser; you do not need to make it externally accessible. This URI must be the same on Azure and Pexip Infinity in order for Azure to validate the sign-in request.

(Available if OAuth for the service account has been enabled)

Enter the URL of the OAuth 2.0 authorization endpoint (v1) (see Taking note of configuration).

Ensure that you use the URL for ... endpoint (v1), not ... endpoint (v2).

(Available if OAuth for the service account has been enabled)

URL of the OAuth 2.0 token endpoint (v1) (see Taking note of configuration).

Ensure that you use the URL for ... endpoint (v1), not ... endpoint (v2).

(Available if OAuth for the service account has not been enabled)

The password of the service account to be used by this VMR scheduling for Exchange integration.

This is the password you assigned when Creating a service account.

The name of the equipment resource that is to be used by this VMR scheduling for Exchange integration.

This is the name you assigned when Creating an equipment resource in Exchange on-premises or Creating an equipment resource in O365.

An equipment mailbox must only be used by a single VMR scheduling for Exchange integration.

The email address of the equipment resource that is to be used by this VMR scheduling for Exchange integration.

This is the email address you assigned when Creating an equipment resource in Exchange on-premises or Creating an equipment resource in O365.

A jinja2 template that is used to generate the name of scheduled conferences. The name is used by the Management Node to identify the conference, and may also appear to conference participants (depending on the endpoint being used).

Note that conference names must be unique, so a random number may be appended if the name that is generated is already in use by another service (Virtual Meeting Room, Virtual Auditorium, Virtual Reception, scheduled conference, Media Playback Service, or Test Call Service).

Default: {{subject}} ({{organizer_name}})

Accepted variables:

• subject
• organizer_email

Default: Scheduled Conference booked by {{organizer_email}}

Accepted variables:

• subject
• organizer_email
• organizer_name
• alias
• numeric_alias

A jinja2 template that is used to generate the subject field of scheduled conferences. This will be shown on the Management Node when viewing information about the conference, and by default will use the subject line of the meeting invitation so the default should be deleted or amended if you do not want administrators to be able to view the meeting subject.

Default: {{subject}}

Accepted variables:

• subject
• organizer_email
• organizer_name
• alias
• numeric_alias

The prefix to use when generating aliases for scheduled conferences.

Note: this must be between 1 and 8 characters long.

The length of the random number suffix part of aliases generated for scheduled conferences.

This must be a number between 6 and 15.

Default: 6.

The set of Identity Providers used to authenticate participants attempting to join scheduled conferences. If this is blank, participants will not be required to authenticate.

For more information, see About participant authentication.

(Available when an Identity Provider Group has been selected)

Determines whether participants joining a SSO-protected service from devices other than the Connect web app (for example SIP or H.323 endpoints) are allowed to dial in to the service.

• Disallow all: these devices are placed in a waiting room where they must wait to be admitted by a Host.
• Allow if trusted: these devices may join the service if they are locally registered. They must still enter a Host PIN or Guest PIN if either is required. All other devices are placed in a waiting room where they must wait to be admitted by a Host.

For more information, see About participant authentication.

Default: Disallow all

The number of minutes before the meeting's scheduled start time that participants will be able to join the VMR.

Range: 0 to 180.

Default: 30.

The number of minutes after the meeting's scheduled end time that participants will be able to join the VMR.

Range: 0 to 180.

Default: 60.

Enable this option to override the default locations from which the add-in JavaScript and CSS are served. This option is intended for use in deployments that are fully offline (where Outlook users will not have internet access) and therefore these resources must be available locally.

If you enable this option, you must host these files on your own internal server, and enter the URLs for each in the relevant fields below.

We recommend contacting your Pexip authorized support representative before enabling this option.

(Available if Use custom add-in sources has been enabled)

The URL used to download the Office.js JavaScript library.

(Available if Use custom add-in sources has been enabled)

The URL used to download the Microsoft Fabric CSS.

(Available if Use custom add-in sources has been enabled)

The URL used to download the Microsoft Fabric Components CSS.

(Available if Use custom add-in sources has been enabled)

Optionally specify additional URLs from which to download JavaScript script files.

These URLs will be used in preference to any other URLs specified elsewhere for the same resource. In particular, we recommend that you specify here the URL for MicrosoftAjax.js.

Each URL must be entered on a separate line.

(Required for single-use VMRs and personal VMRs)

An FQDN or URL which can be used to access a page containing the Exchange Metadata for your Exchange deployment. This page provides the public key of the Microsoft Exchange Server Auth Certificate used by the add-in to verify user identities.

If a FQDN is supplied, the default URL path https://<FQDN>/autodiscover/metadata/json/1 will be used.

This URL must be reachable by the management node.

If you have a hybrid Exchange and Office 365 deployment, you must include outlook.office365.com in the list of domains as well as the domain of one of your Exchange on-premises servers.

If your Exchange deployment uses more than one domain or URL (for example, if you have an on-premises Microsoft Exchange deployment with more than one Microsoft Exchange server, or your Exchange server has more than one FQDN), and they use separate signing certificates, you must include all the FQDNs of all the Exchange servers in your deployment. To do this, select Add another Exchange Metadata Domain or URL and add the FQDN of each.

Inserts the FQDN configured in the Add-in server FQDN field. This FQDN is used by Connect apps as part of the address to use when connecting to the meeting. For more information, see Creating preconfigured links to launch conferences via Connect apps.

Inserts the full alias that was generated for the VMR that will be used for this meeting. This is in the format:

<prefix><random_number>@domain.

Inserts the PXPS:- ID. For more information, see PXPS:- and TOK:- security tags.

The Single-use VMR joining instructions template must contain this variable.

Used in the Reject general error template only

Inserts a UUID which can be used to find more information about the error from the administrator log.

Inserts the end time of the meeting, as per the meeting request. (This time does not include the Join after buffer.)

Note that this will use the format hh:mm on DD/MM/YYYY, e.g. 15:30 on 31/07/2017; this format cannot be changed.

Inserts the numeric part of the alias that was generated for the VMR that will be used for this meeting. This is in the format:

<prefix><random_number>.

Inserts the start time of the meeting, as per the meeting request. (This time does not include the Join before buffer.)

Note that this will use the format hh:mm on DD/MM/YYYY, e.g. 15:30 on 31/07/2017; this format cannot be changed.

Inserts the subject line of the meeting invitation sent by the meeting organizer.

Note that this information will be visible to anyone with access to the Management Node, so do not use this variable if privacy is an issue.

Inserts the FQDN configured in the Add-in server FQDN field. This FQDN is used by Connect apps as part of the address to use when connecting to the meeting. For more information, see Creating preconfigured links to launch conferences via Connect apps.
