Multi Company Microsoft Outlook Integration

Domain-wise Microsoft 365 account setup in Odoo. Configure separate Outlook OAuth2 credentials (Client IDs & Client Secrets) for each company in a multi-company database.

Overview

Multi Company Microsoft Outlook Integration is a premium, essential Odoo extension designed for multi-company or multi-tenant Odoo setups. By default, Odoo restricts databases to a single, global Azure Application Client ID and Client Secret in General Settings. Consequently, all companies and email servers must use the exact same Azure credentials, breaching security boundaries and preventing businesses from using separate Outlook/Office 365 tenants.

Our module bypasses this core limitation by introducing Outlook OAuth Instances. You can now register distinct Azure App registrations (separate Client IDs & Client Secrets) for each company in Odoo. Both Outgoing (SMTP) and Incoming (IMAP) mail servers can be linked to their respective company instances, preserving domain isolation, security compliance, and clean mailing headers across all business units.

Microsoft Graph API Security

Fully secure token-based OAuth2 authentication protocol. Eliminates basic authentication and insecure passwords.

Frequently Asked Questions

Why do I need this module if Odoo already supports Outlook integration?
By default, Odoo restricts Outlook OAuth credentials to a single global Client ID & Client Secret in General Settings. If you run a multi-company database where companies use separate Azure Tenants or distinct domains, they cannot authenticate natively. This module overrides the global restriction by allowing instance-specific configurations per server record.
Can I connect mailboxes from completely different Microsoft 365 tenants?
Yes! Because you can define a unique Client ID and Secret for each Outlook Instance, you can associate different instances with distinct Azure Tenants, allowing completely independent companies to authorize their respective mailboxes securely.
Do I need to manually refresh tokens?
No. Just like standard Odoo, the module stores the refresh tokens securely in the database and automatically requests new access tokens from Microsoft Graph API in the background. Once authenticated, the servers operate seamlessly.
Is this app compatible with Odoo Community as well as Enterprise?
Yes, this app works perfectly with Odoo Enterprise (Odoo.sh & On-Premise) as well as Community editions.
Is this app compatible with Odoo Online?
No, like most 3rd-party modules, this app will not work for Odoo Online (SaaS) as it requires custom module installation which is only permitted on Odoo.sh or On-Premise servers.
How to contact if there is need of any Customization?
Please contact us on support@creyox.com for any custom workflow requirements or specific feature adjustments.
Do I get free support when I buy these app?
Yes, we provide free support for 60 days from the date of purchase for any issues related to the module's standard functionality.
Do I need to buy all versions separately?
Yes, different versions of Odoo (e.g., 16, 17, 18) require their own specific module builds, and these are sold as separate purchases.
The app I paid for is not working, what should I do?
You can raise a support ticket by emailing support@creyox.com. Our technical team will investigate and provide the necessary fixes.
