Question 1

What is a SharePoint extranet?

Accepted Answer

A SharePoint extranet is a SharePoint Online site or portal accessible to external users (partners, suppliers, customers, auditors, board members) outside your organisation, without a Microsoft 365 licence. External users sign in with their own identity (Microsoft, Google, email OTP) via Entra ID B2B. CNEXT builds FADP-compliant SharePoint extranets.

Question 2

How does Microsoft Entra ID B2B enable SharePoint extranet access?

Accepted Answer

Entra ID B2B invites external users as 'guests' in your tenant. They sign in with their own work account (from any identity provider supporting SAML/OpenID Connect) or a one-time passcode. CNEXT configures B2B: invitation policies, guest access expiry (60–180 days), MFA requirements for guests, access reviews and cross-tenant access settings.

Question 3

What is Power Pages and when is it better than SharePoint for an extranet?

Accepted Answer

Power Pages (formerly Power Apps Portals) is Microsoft's external portal builder: no-code site builder, anonymous or authenticated access, forms, database integration (Dataverse) and full custom branding. CNEXT recommends SharePoint extranet for document sharing with known partners; Power Pages for customer-facing portals with self-service forms and anonymous access.

Question 4

How does CNEXT secure a SharePoint extranet?

Accepted Answer

CNEXT security for SharePoint extranets: MFA required for all external users (Conditional Access), Sensitivity Labels on documents shared externally (prevent download of confidential files), access expiry and automatic reviews (Entra ID Identity Governance), SharePoint external sharing audit reports, DLP policies and guest activity monitoring in Microsoft Sentinel.

Question 5

Can external users edit SharePoint documents in an extranet?

Accepted Answer

Yes. External users can co-author Office documents in the browser (or Office desktop apps if configured). CNEXT configures sharing settings: 'Can edit' vs. 'Can view' per document library. For highly sensitive documents, 'Can view' only with download blocked (via Sensitivity Labels) is recommended.

Question 6

Can a SharePoint extranet replace a physical data room for due diligence?

Accepted Answer

Yes. CNEXT builds SharePoint virtual data rooms for M&A due diligence, fundraising and audits: granular access by document category, access logs (who viewed what, when), download restrictions, watermarking via Sensitivity Labels and automatic access revocation on deal close. FADP-compliant with complete audit trail.

Question 7

How does CNEXT manage SharePoint extranet governance?

Accepted Answer

CNEXT extranet governance: automated guest access expiry notifications (30 days before expiry → prompt for renewal), quarterly Entra ID access reviews (each guest account reviewed by site owner), external sharing audit reports monthly, SharePoint Data Access Governance (DAG) reports for overshared files and Power Automate guest offboarding flows.

Question 8

Can a SharePoint extranet integrate with our CRM?

Accepted Answer

Yes. CNEXT integrates SharePoint extranets with CRM (Dynamics 365, Salesforce): new partner record in CRM → Power Automate creates SharePoint site + sends B2B invitation → access tied to CRM relationship status (active partners only). Contract expiry in CRM → automatic SharePoint access revocation.

Question 9

Is SharePoint extranet suitable for board governance?

Accepted Answer

Yes. CNEXT builds board portals on SharePoint: secure board document library (resolutions, minutes, financial reports), board meeting preparation site (agenda, pre-reading packs), action item tracking and mobile access via SharePoint app. Board members access via B2B guest with MFA – no separate board portal software needed.

Question 10

How much does a SharePoint extranet cost with CNEXT?

Accepted Answer

A simple partner extranet (1 SharePoint site, guest access setup, governance, training): CHF 8,000–20,000. A full partner portal with Power Pages, CRM integration and workflow: CHF 25,000–60,000. A board governance portal: CHF 15,000–35,000. CNEXT provides fixed-price quotes after a discovery workshop.
