Plenty of organizations run Salesforce for CRM and Microsoft 365 for document storage, so sooner or later somebody asks to have the two connected. The trouble is that "connect Salesforce and SharePoint" covers several distinct requests:
- Access: users can view and open SharePoint files directly from Salesforce records.
- Organization: files land in the right SharePoint locations automatically, based on Salesforce data, so nobody is filing by hand.
- Process: documents get generated, moved, and shared as part of automated Salesforce workflows.
Work out which of those you are actually being asked for before you pick a method. That answer decides everything else.
Integration methods for Salesforce and SharePoint
1. Salesforce Files Connect (native)
Files Connect is built into Salesforce and surfaces external files, SharePoint included, in the Salesforce Files tab. Nothing gets copied into Salesforce; the files stay in SharePoint. There is no licensing cost from Salesforce.
Technical considerations:
- You configure external data sources, authentication providers, and permission sets.
- Search and preview can be inconsistent.
- It is reference-only. There is no record-triggered document automation.
Best suited for: occasional, manual access to SharePoint files from Salesforce records.
2. Manual upload and download
The most basic approach. Users download files from one system and upload them to the other.
Technical considerations:
- No setup, no licensing cost.
- Duplicate files, version sprawl, and human error come with the territory.
- It stops scaling as soon as document volume or user count grows.
Best suited for: very small teams with minimal document volume and no strict compliance requirements.
3. iPaaS and middleware solutions (e.g., MuleSoft, Zapier)
Integration Platform as a Service tools sit between Salesforce and SharePoint and sync files and metadata against rules you define.
Technical considerations:
- Powerful and flexible.
- You build the integration flows, and you maintain them.
- Document sync may not be what the platform is best at, so expect less out-of-the-box behavior.
- Ongoing maintenance, and the platform itself costs money.
Best suited for: organizations already invested in an iPaaS platform with the in-house skill to run custom integrations.
4. Custom Apex and Microsoft Graph API
You write Apex inside Salesforce that talks to the Microsoft Graph API, with granular control over read, write, and sync operations on SharePoint files.
Technical considerations:
- Complete customization and control.
- It can get complex and expensive to build and maintain.
- Changes to the Microsoft Graph API can force changes to your Apex.
- You need real development capacity in-house for edge cases and shifting requirements.
Best suited for: organizations with strong in-house development teams and highly specific requirements nothing off the shelf covers.
5. Purpose-built document automation applications
These are Salesforce-native managed packages built for external document management and automation. They range from simple sync connectors up to full document workflow platforms.
Technical considerations:
- CloudFiles is one example, and it is aimed at process automation.
- Folders are created automatically and linked to Salesforce records.
- SharePoint's native permissions are respected.
- Document actions such as sharing, uploads, and transfers can fire from Salesforce Flow without custom code.
- Many are storage agnostic and also work with Google Drive, AWS S3, or Azure Blob.
Best suited for: teams that want automated, record-aware document workflows without much development effort.
Choosing the right integration approach
It comes down to how far you need to go:
- Access: if users only need to open SharePoint files from Salesforce records, Files Connect or manual uploads are enough, and cheap.
- Organization: automated file placement and management needs iPaaS, custom development, or a purpose-built application.
- Process: generating, moving, and sharing documents off the back of Salesforce record changes needs a serious automation platform or a substantial custom build.
Integration method summary
| Method | Level Delivered | Automation | Dev Effort | Best Fit |
|---|---|---|---|---|
| Files Connect | Access | None | Low setup | Light manual reference |
| Manual Upload/Download | Access (plus manual) | None | None | Tiny teams, low volume |
| iPaaS / Middleware | Up to Process (DIY) | High | Medium to high | Existing middleware orgs |
| Custom Apex + Graph API | Any (you build it) | Full | High | Dev-heavy, unusual needs |
| Purpose-built app (e.g. CloudFiles) | Process, out-of-the-box | High, no-code | Low | Automated, record-aware workflows |
