My Sites In SharePoint

My Sites in SharePoint: Configuration Guide

My Sites in SharePoint gave each user a personal workspace for document storage, profile management, and social collaboration. In SharePoint Online and Microsoft 365, My Sites have been replaced by OneDrive for Business and the Microsoft 365 user profile. EPC Group manages My Site migrations, OneDrive governance, and user profile architectures for enterprises with 50,000+ users.

My Sites in SharePoint Server (on-premises)

My Sites in SharePoint Server (2013, 2016, 2019) provide a personal site for each user. Each site includes:

• Personal document library: private file storage accessible only to the user.
• Shared document library: files the user shares with colleagues.
• About Me page: user profile with skills, interests, and org chart position.
• Newsfeed: social activity stream (replaced by Yammer/Viva Engage in later versions).
• Followed content: sites, documents, and people the user follows.

My Sites in SharePoint Online (Microsoft 365)

In Microsoft 365, the My Site architecture has three components. Each replaced part of the on-premises My Site.

• OneDrive for Business: replaces the personal and shared document libraries. 1 TB per user by default.
• Microsoft 365 profile: replaces the About Me page. Integrates with Delve, LinkedIn, and Viva Insights.
• Viva Engage / Yammer: replaces the Newsfeed for org-wide social collaboration.

My Site migration considerations

When migrating from SharePoint on-premises to SharePoint Online, My Site content must be handled separately from team sites.

• Personal document libraries → OneDrive for Business (user-by-user migration).
• User profile data → Microsoft 365 profile (synced from Azure AD and HR systems).
• Followed content → re-established in SharePoint Online after migration.
• Permissions on shared My Site documents must be validated post-migration.
• SharePoint Admin Center controls My Site host URL and storage quotas.

OneDrive governance

EPC Group configures OneDrive governance policies to protect user data and meet compliance requirements.

• Storage quotas by user group or license tier.
• External sharing policies — restrict sharing to verified domains.
• Sensitivity labels via Microsoft Purview — auto-classify files by content type.
• Retention policies — configure default retention for OneDrive content.
• Data lifecycle management — archive OneDrive of departing employees.

Frequently asked questions

What happened to My Sites in SharePoint Online?

My Sites were replaced by OneDrive for Business (personal file storage) and the Microsoft 365 user profile (About Me, skills, org chart). The Delve experience surfaces profile information. Viva Engage replaced the social newsfeed.

How do I migrate My Site content to OneDrive?

Use the SharePoint Migration Tool (SPMT) or Microsoft FastTrack for My Site document library migration to OneDrive. Permissions must be remapped manually. User profile data syncs separately via Azure AD. EPC Group handles enterprise-scale My Site migrations with zero data loss.

Can users access their old My Site after migrating to Microsoft 365?

No. Once the on-premises SharePoint environment is decommissioned, the My Site URL goes offline. Content must be migrated to OneDrive before cutover. EPC Group validates content migration and notifies users of their new OneDrive URL as part of every engagement.

How much OneDrive storage does each user get?

Microsoft 365 Business and Enterprise plans include 1 TB of OneDrive storage per user by default. Admins can set individual user quotas up to the tenant limit. Microsoft 365 E3 and E5 plans include unlimited archiving for Exchange but OneDrive quotas are managed separately.
