[Introduction]<\/b><\/p>\n

We\u2019re retiring the OneView <\/b>and TrueTime<\/b> features from Outlook Web App (OWA)<\/b>. OneView <\/b>allows users to connect personal email accounts\u2015such as Outlook.com, Gmail, or other IMAP accounts\u2015to their work mailbox in OWA, providing a unified view of multiple inboxes. TrueTime<\/b> allows users to view personal and work calendars together in OWA for consolidated scheduling. Once these features are retired, users will no longer be able to connect personal accounts or view personal calendar information inside OWA.<\/p>\n

[When this will happen:]<\/b><\/p>\n

This retirement will begin in early March 2026<\/b> and complete by late June 2026<\/b>.<\/p>\n

[How this affects your organization:]<\/b><\/p>\n

Who is affected:<\/b><\/p>\n

<\/p>\n

    <\/p>\n
  • Users who currently use OneView <\/b>or TrueTime<\/b> in OWA.<\/li>\n

    <\/p>\n

  • Users who have connected work and personal accounts within OWA.<\/li>\n

    <\/ul>\n

    What will happen:<\/b><\/p>\n

    <\/p>\n

      <\/p>\n
    • OneView <\/b>and TrueTime<\/b> features will be removed from OWA.<\/li>\n

      <\/p>\n

    • Users will no longer be able to connect or access personal accounts within OWA.<\/li>\n

      <\/p>\n

    • Existing connected accounts will be automatically disconnected.<\/li>\n

      <\/p>\n

    • Users must manually schedule corresponding events across calendars if needed.<\/li>\n

      <\/p>\n

    • No admin configuration changes are required; the retirement occurs automatically.<\/li>\n

      <\/ul>\n

      [What you can do to prepare:]<\/b><\/p>\n

      <\/p>\n

        <\/p>\n
      • No admin action is required.<\/li>\n

        <\/p>\n

      • Notify your users about this retirement.<\/li>\n

        <\/p>\n

      • Update internal helpdesk guidance and documentation.<\/li>\n

        <\/p>\n

      • Direct users who need multi-account support to Outlook for Windows or Mac.<\/li>\n

        <\/ul>\n

        [Compliance considerations:]<\/b><\/p>\n

        No compliance considerations identified, review as appropriate for your organization.<\/p>\n<\/td>\n<\/tr>\n
