Office 365 AI Email Integration
Blumac Digital developed a bespoke Office 365 email integration that connects monitored inboxes to a client’s business management system in real time. Using Microsoft Graph API webhooks and AI-powered email classification, the system automatically reads incoming emails, analyses their content, and allocates each one to the correct quote or order record - eliminating hours of manual sorting every week.
The brief
The challenge
Our client managed hundreds of incoming emails each week across multiple shared Office 365 inboxes. Staff were manually reading each email, identifying which quote or production order it related to, and filing it in the correct place within their order management system. This manual email processing was time-consuming, error-prone, and meant urgent communications were sometimes missed or misallocated. They needed an intelligent email routing solution that could think for itself.
Why bespoke?
Off-the-shelf email automation tools like Power Automate or Zapier work for simple rules, but they cannot match emails against your own business data with contextual AI understanding. This bespoke integration demonstrates how combining the Microsoft Graph API for real-time email delivery with AI-powered classification creates a system that saves hours of administrative work every week - while being more accurate than the manual process it replaced.
What it delivered
Eliminated Manual Email Sorting
Staff no longer spend time reading and filing emails. The AI email processing system handles each email within seconds of arrival, freeing the team to focus on their actual work.
Improved Allocation Accuracy
AI-powered classification reduces human error. Reference numbers, project names and even fuzzy name variations are caught consistently, and low-confidence matches are held back for review rather than being filed incorrectly.
Complete Audit Trail
Every processed email is logged with its matched record, the actions taken, and the result. Nothing falls through the cracks, and management has full visibility of the email pipeline.
Seamless Office 365 Integration
Built directly on the Microsoft Graph API, the integration runs within the existing Laravel application and AWS infrastructure. No separate email servers, no IMAP polling - just real-time webhooks from Microsoft 365.
Our solution
What we built
Automated Email Allocation Using AI and the Microsoft Graph API
Real-Time Email Webhooks via Microsoft Graph API
The system registers Microsoft Graph API webhook subscriptions on monitored Office 365 mailboxes. When a new email arrives, Microsoft sends an instant change notification to our application - no polling, no delays. Subscriptions are automatically renewed before expiry, ensuring uninterrupted email monitoring around the clock.
Configurable Rule Engine
A flexible rules engine routes emails based on sender patterns, subject line matching and folder type. Rules are configured by the business team without any code changes, and each rule can trigger a different processing action - from quote allocation to production order assignment.
AI-Powered Email Classification and Record Matching
This is where the integration truly shines. AI agents analyse the sender, subject line and full email body, then compare them against existing quotes and orders for that customer. The AI email classification engine looks for reference numbers, project identifiers and contextual name matching - even handling typos and abbreviations. Only high-confidence matches are automatically allocated; anything uncertain is flagged for human review, ensuring accuracy without losing speed.
Attachment & Inline Image Processing
The system downloads and catalogues every attachment - PDFs, images, spreadsheets and even embedded .eml files with their own nested attachments. Inline images referenced via CID are resolved and replaced with permanent URLs, so the email renders perfectly when viewed later within the management system.
Automatic allocation to records
Each message is allocated to the correct quote or production order automatically, removing the manual sorting step entirely.
Multiple monitored inboxes
Several shared Office 365 inboxes are monitored at once, so nothing depends on one person watching one mailbox.
