Bitrix24 and Microsoft 365 Integration: Exchange, SharePoint, SSO

Managers copy emails from Outlook into deal comments, leaders create meetings in the calendar—participants don't see them in Bitrix24. Files are approved in SharePoint, but the deal card holds an outdated version. Sound familiar? We encounter such scenarios daily and know how to automate them. Bitrix24 integration with Microsoft 365 eliminates manual data transfer and reduces approval time by 30–50%. For example, on a project with 200 users, manual calendar synchronization consumed up to 2 hours per manager per week—after automation, it dropped to 10 minutes. Operational cost savings amounted to about 1.5 million RUB per year. Get a consultation—we'll evaluate your project in one hour.

How to Synchronize Outlook and Bitrix24 Calendars?

Calendar synchronization is the first request in integration. Meetings from Outlook appear in B24 and vice versa. Setup:

• In B24: Calendar → Settings → Sync with Outlook / Exchange
• For cloud Microsoft 365—authorization via OAuth 2.0 (Azure AD)
• For on-premise Exchange Server—connection via CalDAV or Exchange Web Services

Synchronized fields:

Nuances:

• Meeting rooms—Exchange resources do not sync with B24. Booking remains in Outlook.
• Invitations—if a meeting is created in B24, participants receive a notification in B24, not an Outlook invitation. And vice versa. Designate one system as primary for meetings.
• Latency—synchronization via Microsoft Graph API updates every 5–15 minutes. For critical scenarios, we configure webhook subscriptions (change notifications).

OneDrive and SharePoint ↔ B24 Drive

Two options for connecting Microsoft cloud storage:

OneDrive (personal). Each employee connects their OneDrive to B24 Drive: Drive → Connect storage → OneDrive. Files are accessible from the B24 interface and can be attached to tasks and deals.

SharePoint (team). For shared document libraries. We connect specific SharePoint libraries to B24 Drive. The entire team sees one file structure.

Features:

• Office documents (.docx, .xlsx, .pptx) open in Office Online directly from B24
• File versioning is managed on the OneDrive/SharePoint side—B24 displays the current version
• Co-authoring via Office Online works when opening from B24
• Limitation: B24 business processes (approval workflows) apply only to files on B24 Drive. Files in SharePoint must first be copied.

Exchange Mail ↔ CRM

Connecting Outlook mail to Bitrix24 CRM links correspondence with client data. Setup:

1. CRM → Mail → Connect mailbox—select Microsoft 365, authorize via OAuth
2. Link to CRM—incoming emails automatically attach to contacts and companies. New addresses create a lead.
3. Send from CRM—email is sent from the deal card through the manager's Outlook account. A copy is saved both in CRM and in the Outlook Sent Items folder.

Additionally:

• Email templates—standard replies with CRM data substitution (name, amount, products)
• Open tracking—the manager sees if the client opened the email
• Routing rules—emails from specific domains are automatically assigned to the responsible manager

For clarity, here are the email integration features:

Why SSO is More Convenient Than Separate Authentication?

Single sign-on via corporate Microsoft account—employees authorize in B24 with the same login and password as in Outlook, Teams, SharePoint. It's 10 times more convenient than remembering different passwords.

Setup for cloud B24:

• Portal → Settings → Authorization → Enable "Sign in with Microsoft"
• Employee clicks "Sign in with Microsoft" → Azure AD confirms → access to B24

Setup for on-premise B24:

1. In Azure Portal → App registrations → create an application
2. Specify Redirect URI (B24 portal address)
3. Obtain Application (client) ID and Client Secret
4. Configure in B24 module "Social Services" settings
5. Set attribute mapping: email, name, department

Comparison of SSO and separate authentication:

Advantages:

• Single management point—blocking an account in Azure AD blocks access to B24
• Conditional Access—Azure AD policies (allowed IPs, devices, MFA) apply to B24 login
• Automatic user creation—on first SSO login, the user is created in B24 with a profile populated from Azure AD (SCIM provisioning—via middleware)

Interaction with Microsoft Teams

There is no direct native integration of B24 with Teams, but working scenarios exist:

• B24 tab in Teams—add the B24 portal as a tab in a Teams channel. The employee opens CRM or tasks without leaving Teams.
• Notifications via webhook—events from B24 (new lead, overdue task, completed approval) are sent to a Teams channel via Incoming Webhook.
• Power Automate—connect B24 REST API and Microsoft Power Automate for automation: task created in B24 → message in Teams; email with keyword in Outlook → lead created in B24.

What's Included

• Two-way synchronization of Outlook Calendar and B24 calendar
• Connection of OneDrive and SharePoint to B24 Drive
• Exchange mail integration with CRM: email linking, sending from card, tracking
• SSO via Azure AD with Conditional Access and automatic provisioning
• Notifications from B24 to Microsoft Teams via webhook
• Automations via Power Automate (B24 REST API ↔ Microsoft Graph API)
• Team training on working with B24 + Microsoft 365
• Documentation on setup and operation, working access, support during implementation

How a corporate portal on Bitrix24 solves the problem of information chaos?

Employees spend up to 2 hours a day searching for files, emails, and solutions. Tasks get lost in dozens of chats, approvals get stuck for weeks. The manager learns about missed deadlines only at a meeting. A corporate portal on Bitrix24 ties every message, document, and task to a single context. You get a transparent picture of work: who is working on what, which stages, where bottlenecks are. Wikipedia: Information silo describes how unorganized data reduces productivity – a portal cuts that loss by 60–70%.

We will evaluate your project for free – contact us to get the architecture in 2 days. A medium‑sized company typically saves 2.5 million rubles annually after deployment (based on our projects).

What does the portal offer in daily work and why is it better than messengers?

In messengers, information is unstructured – discussions get buried within a week. On the portal, every message is tied to a task, project, or document. Employees spend up to 30% of their work time searching for data (McKinsey). The portal reduces this time by 2–3 times thanks to structured repositories and full‑text search.

Communications. Activity stream, messenger, and video calls are tied to specific tasks. Any discussion can be found six months later – in a messenger it would be buried within a week.

Tasks and projects. Kanban, Gantt, checklists, dependencies, time tracking. Each employee's efficiency is visible in reports – no need to wait for a meeting.

Document flow. Approval routes through the business process designer: leave request → manager → HR → accounting. Electronic signature, versioning, deadline control. Integration with electronic document management (SBIS, Diadoc) via REST API.

HR. Onboarding of new employees, leave/travel requests, organizational structure, absence schedule. An employee knows where to go from day one.

Knowledge base. Bitrix24 wiki engine: regulations, instructions. Knowledge does not leave with departing employees.

Implementation example. For a manufacturing company with 320 employees, we deployed a portal with integration of 1C:SALARY AND HR MANAGEMENT and Active Directory in 4 months. Travel request approval time decreased from 3 days to 4 hours. Savings on employee idle time amounted to 1.5 million rubles per year. Managers receive automatic reports on department efficiency. Customer response time decreased by 20%. Portal payback period is 7 months.

How does integration with 1C and Active Directory accelerate HR management?

Integration with 1C:Enterprise via the b24connector module or custom REST handler: a leave request is approved on the portal through a business process and automatically enters 1C:SALARY AND HR MANAGEMENT for vacation pay calculation. Active Directory (SSO via the ldap module) – the employee account is created once in AD and synchronized to the portal, email, VPN. Upon dismissal, it is blocked everywhere. Manual account creation is eliminated, errors are minimized.

Types of corporate portals and key integrations

Additional integrations that deliver real value:

• Email: Exchange via EWS API or IMAP, calendar synchronization, creating a task from an email.
• IP telephony: Asterisk, Mango Office, Zadarma via REST API – calls from the portal, contact card, call recording.
• Video conferencing: built‑in video calls or integration with Zoom/Teams via marketplace.
• EDI: SBIS, Diadoc via REST API – fully electronic document flow with counterparties.

Security and compliance with Federal Law 152‑FZ

The portal contains personal data, financial reports, strategic plans. We guarantee protection:

• role model via CGroup and section‑level permissions;
• two‑factor authentication (OTP, Yandex.Key, SMS);
• audit of all actions (b_event_log);
• TLS encryption for transmission and disk encryption;
• full compliance with Federal Law No. 152‑FZ "On Personal Data".
