doclinc vs Microsoft 365

You already have Microsoft 365. Here's where secure document sharing still breaks.

Microsoft 365 is a powerful platform — for internal collaboration. But when it comes to sharing sensitive documents with external recipients, the friction, risk, and cost often tell a different story.

This is not a replacement for Microsoft 365. It's a complement for one specific use case that native tools don't handle well.

Feature comparison

Side-by-side Comparison

Where Microsoft 365 excels, we say so. Where it creates friction for external document sharing with non-technical recipients, we explain why.

Real risk

The SharePoint folder problem

Security Risk

When a shared folder is misconfigured, the external recipient can browse the entire directory — not just the file you intended to share.

This is one of the most common data exposure incidents in organizations using SharePoint for external sharing. An employee shares a OneDrive or SharePoint folder link with a client, prospect, or partner. If the sharing settings inherit from the parent folder or if the link type is set to "Anyone with the link," the recipient may be able to navigate up the directory tree and access files that were never intended to be shared — payroll documents, internal reports, confidential contracts.

This isn't a hypothetical. Microsoft itself acknowledges it in their sharing best practices documentation. But configuring these settings correctly requires IT expertise, and human error is inevitable at scale.

How doclinc handles this: There are no shared folders in doclinc. Every document exchange is a self-contained, scoped transaction. Recipients access only what was explicitly sent to them, for the duration you define. There is no directory to navigate, no inheritance to misconfigure.

Security threat

Why Microsoft 2FA doesn't fully protect document access

Multi-factor authentication is an important security layer — but a specific class of attack specifically targets MFA-protected Microsoft 365 accounts.

The Threat — AiTM Phishing

Adversary-in-the-Middle attacks bypass Microsoft 2FA

Tools like Evilginx2 act as a transparent proxy between the victim and Microsoft's login page. The attacker captures the authenticated session cookie in real time — even after successful 2FA. Once they have the session cookie, they can access OneDrive, SharePoint, and email without needing the password or MFA code again.

How doclinc is different

No Microsoft session to intercept

When a recipient accesses a document via doclinc, there is no Microsoft authentication session involved. Access is granted through a unique, time-limited link combined with a one-time PIN delivered via SMS or voice call. There is no reusable session cookie, no username/password flow. An AiTM attack targeting a Microsoft login page has nothing to intercept.

Total cost of ownership

The real cost of advanced Microsoft security features

The native Microsoft tools that would let you approach doclinc's level of control — Purview, MIP, advanced compliance — are typically gated behind Microsoft 365 E5 licensing.

Microsoft 365 E5: the price of full control

Microsoft 365 Business Standard covers basic productivity. For advanced data protection, retention policies, sensitivity labels, and compliance features comparable to what doclinc provides by default, organizations generally need E3 at minimum — or E5 for the full suite. For most SMBs, jumping to E5 to solve a document-sharing use case is not practical or cost-effective.

Time to value

How long before it actually works?

Configuring Microsoft Purview, MIP sensitivity labels, and retention policies is a multi-month project requiring dedicated IT resources. doclinc is operational the same day.

Data residency

Where your data actually lives — and how you can prove it

Microsoft lets you choose a primary data region. But for most SMBs, verifying that all data — including service logs, AI features, and diagnostic telemetry — truly stays within that region is harder than it sounds.

Microsoft 365 — Complex

Choosing a region isn't the same as staying in it

Microsoft allows organizations to select a primary data region (e.g. Canada). However, certain service data — including diagnostic telemetry, support data, Microsoft 365 Copilot processing, and some compliance features — may be processed in secondary regions regardless of your primary selection.

Documenting that your clients' personal data never left Canada for a Law 25 or PIPEDA audit requires interpreting Microsoft's Data Residency documentation, running Data Location reports in the admin center, and often engaging IT or legal counsel — not a one-click answer.

doclinc — Clear & Simple

AWS ca-central-1 — Canada only

doclinc is hosted exclusively on AWS ca-central-1 (Canada Central — Montréal/Ottawa region). Document data, transaction metadata, and access logs never leave Canadian infrastructure.

There are no secondary processing regions, no AI features that route data abroad, and no ambiguity about where your clients' documents are stored.

For Law 25 compliance: Each transaction produces a timestamped audit trail you can present to a compliance officer without parsing admin portals or interpreting Microsoft's residency documentation.

Concrete use cases

Where native tools create friction

These are the exact scenarios where organizations move to doclinc — not instead of Microsoft 365, but alongside it.

Accounting firm sending T4s

⚠ Client uses Gmail. SharePoint guest access fails. Link shared via email is accessible to anyone.

✔ Sends from Outlook, recipient authenticates with SMS PIN, document expires after 7 days.

Law firm sharing contracts

⚠ External parties from multiple firms. Guest accounts impractical. Folder permissions misconfigured.

✔ Per-transaction access, no accounts, full audit trail, auto-deletion after signing.

HR distributing pay stubs

⚠ Employees on different domains. Email attachments uncontrolled. Forwarded or printed unintentionally.

✔ Personal secure link per employee. Access logged. Document expires after retrieval period.

Common questions

Objections we hear — answered honestly

That may be true for basic internal file sharing. But the specific capabilities doclinc provides — passwordless external authentication via SMS/voice OTP, automatic expiry, per-transaction scoped access, phishing-resistant flows, and Outlook-native UX — require Microsoft 365 E5 or a combination of add-ons that quickly exceed the cost comparison. For SMBs that don't need full E5, doclinc is a focused, lower-cost solution for the specific use case of secure external document exchange.
OneDrive links work — until they don't. "Anyone with the link" means exactly that: the link can be forwarded, shared unintentionally, or remain accessible long after it should have expired. Without enforced authentication, retention policies, and scope isolation, every shared link is a potential exposure vector. If your compliance requirements include Law 25, PIPEDA, or GDPR, those links may not meet the documentation standards required.
Absolutely — and for large enterprises with dedicated IT and security teams, that may be the right path. doclinc is designed for organizations that either don't have that capacity, don't want to maintain that configuration overhead, or need a faster path to compliant external sharing. The two approaches aren't mutually exclusive.
No. doclinc lives inside Microsoft Outlook as an add-in. It extends what you already have — it doesn't replace anything. Your team continues to use Outlook, Teams, SharePoint, and OneDrive for everything they do today. doclinc handles one specific workflow: securely sending and receiving sensitive documents with external recipients who may or may not have Microsoft accounts.
2FA significantly reduces account compromise risk — but it doesn't protect against Adversary-in-the-Middle (AiTM) phishing attacks, which specifically target the session token after a successful 2FA authentication. These attacks don't steal your password or your MFA code; they steal the authenticated session. Microsoft's own security advisories acknowledge this attack class. doclinc's access model doesn't use session tokens that can be intercepted — each access is a one-time event with a single-use OTP.
