does Office for Mac work properly with macOS Tahoe26.3.1 installed on my MacBook Pro

Office for Mac is supported on macOS Tahoe (26) and is expected to work properly, provided the Mac meets the general system requirements for Microsoft 365 or Office for Mac.

Key points from current support policy:

1. Support status for Tahoe
   • Microsoft 365 for Mac, Office 2024 for Mac, and Office 2021 for Mac support the three most recent major versions of macOS.
   • As of September 2025, those versions are macOS Tahoe (26), macOS Sequoia (15), and macOS Sonoma (14).
   • macOS Tahoe is explicitly listed as supported starting with the September 2025 update (16.101). For the best experience, Office apps should be updated to the latest build after upgrading macOS.
2. Updates and security
   • On a supported macOS version like Tahoe, Office apps continue to receive all updates, including security updates and new features.
   • If macOS is not updated to a supported version, Office apps still run but no longer receive updates.
3. Known issues and third‑party add‑ins
   • Some reported problems on Tahoe are related to third‑party components (for example, Adobe PDF add‑ins such as SaveAsAdobePDF.xlam or older Acrobat integrations) rather than Office itself. In those cases, the recommended path is to update or remove the third‑party add‑ins and, if needed, contact the third‑party vendor (such as Adobe) for fixes.
   • Reinstalling Office has resolved certain Tahoe‑related behavior for some users when the issue was due to conflicts or corrupted installations.

Practical guidance before upgrading to Tahoe 26.3.1:

1. Ensure the installed Office for Mac version is current (via Microsoft AutoUpdate) before and after the macOS upgrade.
2. After upgrading to Tahoe, run Microsoft AutoUpdate again to get the latest supported Office build (16.101 or later when available).
3. If Adobe or other third‑party Office add‑ins are installed, verify they are updated for compatibility with both Tahoe and the current Office build, or temporarily disable/remove them if issues appear.

With these steps, Office for Mac is expected to work properly on macOS Tahoe 26.3.1.
