Important

We won’t take any active measures to block other versions of the Office client, such as Office 2013, from connecting to Office 365 services, but these older clients may encounter performance or reliability issues over time.

Impact of using older Office clients to connect to Office 365 services

After October 13, 2020, ongoing investments to our cloud services will not take into account older Office clients. Over time, these Office clients may encounter performance or reliability issues. Organizations that use these older clients will almost certainly face an increased security risk and may find themselves out of compliance depending upon specific regional or industry requirements.

Therefore, administrators should update older Office clients to versions of Office supported for connecting to Office 365 services.

Upgrade resources available to administrators

We recommend that you upgrade older Office clients to a subscription version of the Office client, such as Microsoft 365 Apps for enterprise. The most up-to-date subscription versions of the Office client are always supported connecting to Office 365 services.

We provide various services to help you upgrade to subscription versions of the Office client. The following list provides some examples of resources that are available:

  • Microsoft FastTrack, for migration and deployment assistance from Microsoft experts.
  • App Assure, for assistance from Microsoft with application compatibility issues.
  • Deployment guide for Microsoft 365 Apps, for technical documentation.
  • Product lifecycle dashboard and upgrade readiness dashboard, for users of Microsoft Endpoint Configuration Manager (current branch).
  • Readiness Toolkit for Office add-ins and VBA, to help identify potential issues with add-ins and VBA macros used in your organization.
