Microsoft Office appears to be experiencing activation issues on both Mac and PC today, according to several user reports on Twitter. MacRumors also received emails from multiple readers affected.
At least some Office 365 subscribers who have attempted to use Word, Outlook, and other apps in the Microsoft Office suite have been prompted to reactivate their license, but the process fails to complete.
Affected users have encountered various errors while Office apps hang on "activating" or "looking for licenses," which eventually leads to a window that says "no license found," with seemingly no workaround.
Hi @Microsoft, Is @Office365 having trouble with it's activation service right now? Just updated @Office for #macOS and it asked to be activated (again). Tried 3x over the past half-hour or so. pic.twitter.com/9VeLR0bVOC — Henry Ferlauto (@HTFIII) August 16, 2018
The issue appears to be affecting not only individual users, but businesses and universities and with enterprise licenses.
Update: A spokesperson for Microsoft says "our team has addressed the issue and is continuing to monitor to ensure complete resolution."
