office 32 bit

The office 32 bit tag covers Microsoft 365 Apps guidance for organizations that continue to use 32-bit Office installations and dependent add-ins. Current coverage focuses on Version 2606, which does not force a migration to 64-bit Office, and on the compatibility considerations for 32-bit COM and VSTO add-ins. The discussion emphasizes representative testing before deploying the July 14, 2026 update to add-in-dependent devices. Higher-risk systems may remain on Version 2508 while testing continues, with September 8, 2026 identified as the relevant testing deadline. The tag is useful for tracking Office architecture, deployment timing, and add-in compatibility concerns.
