microsoft 365 group calendars

The microsoft 365 group calendars tag covers Outlook shared-calendar issues affecting recurring meetings, delegates, and meeting attachments. Current guidance focuses on Microsoft’s investigation into classic Outlook behavior where editing one instance of a recurring meeting may update every instance, while delegates sending attachment-related updates may result in recipients not receiving all content. The tagged discussion recommends that organizations pause broad deployment of shared-calendar improvements, run limited pilots with users managing delegated calendars or recurring group-calendar meetings, and use SharePoint or OneDrive links for meeting materials when delegates make updates. It is intended for administrators assessing workflow risks before wider rollout.
