Microsoft has informed IT administrators that Microsoft 365 Enterprise programs (Word, Excel, etc.) set to the semi-annual update channel will be automatically migrated to the monthly update channel. Employees who receive monthly Office updates are said to be more satisfied, according to the company.
Microsoft has multiple update channels for programs in a Microsoft 365 subscription (formerly Office 365). There is the ‘Current Channel’ where the latest updates are loaded immediately, the ‘Monthly Enterprise Channel’ where this happens monthly, and then the semi-annual ‘Semi-Annual Enterprise Channel’. The last two, as the name suggests, are for Enterprise subscribers only. There are also ‘Beta’ and ‘Current Channel (Preview)’ channels for Office Insider users.
If changes are not desired, IT admins can indicate in the Microsoft 365 admin center that they still want to stay in the biennial update channel.
