Microsoft Office 2011 Update For Mac Sierra
Office 2016 for Mac is fully supported on High Sierra. For the best experience, we recommend you update Office to version 15.38 or later. For updates regarding macOS 10.14 Mojave, see Microsoft Office support for macOS 10.14 Mojave. Microsoft today released an update for Microsoft Office for Mac 2011, which fixes a significant Outlook bug that Office users ran into after upgrading to OS X El Capitan. Microsoft has announced in a support document that Office for Mac 2011 will not be supported under macOS 10.13 High Sierra. It doesn’t go as far as to say the software will not work, but hints.

On the other hand, it’s hard to believe that the Office for Mac team hasn’t devoted some effort to testing Office 2011 on the upcoming macOS. Aside from the support deadline, Redmond has a vested interest in getting anyone with Office 2011 to hand over more money for Office 2016/Mac. Staying quiet on compatibility of Office 2011 serves Microsoft’s ends. MacOS ‘High Sierra’ a big deal Usually macOS upgrades aren’t a major issue for Office compatibility but ‘High Sierra’ is different. Apple is changing the entire disk/file system which is a major change that needs careful testing for programs like Office. Gone is the 30-year-old HFS+ system in favor of APFS Apple File System. APFS has many new features but the one of most relevance to Office users is encryption.
Unlike most file systems (including Microsoft’s NTFS), Apple File System has been designed with encryption in mind. An entire drive can be encrypted, much like Windows Bitlocker. There’s also a multi-key system with different keys for file and metadata.

Patience, Grasshopper Because of this fundamental change to macOS, it’s prudent to wait for the public release of ‘High Sierra’ (and even then, maybe a few weeks more). When you do upgrade macOS, do a full backup first and upgrade Office 2016 for Mac to the latest release before the macOS update.
