OneView and TrueTime Retirement Removes Personal Account Access in OWA

For years, users have relied on Outlook web to manage both their work mailbox and personal accounts in one place. Features like OneView and TrueTime made it possible to manage meetings, appointments, and reminders without switching between apps.

That convenience is about to change.

Microsoft is retiring the OneView and TrueTime features in Outlook Web App. If you’ve been using OWA as your ‘all-in-one’ hub, this update will shift how you manage your personal schedules. Let’s look at the transition and what it means for your daily routine.

Below is a quick look at what these features provided.

• OneView: This feature allowed users to connect personal email accounts such as Outlook.com, Gmail, or other IMAP accounts to their work mailbox in OWA. It helped manage multiple accounts from a single interface without switching apps.

• TrueTime: With this feature, users can add and view personal calendars in OWA. The combined view made it easier to see personal and work calendars together. It also helped users plan schedules and reduce conflicts between personal and professional commitments.

The retirement of these features begins in early March 2026 and is expected to be completed by late June 2026.

Here’s how this change will affect users:

• Existing personal accounts and calendars will be disconnected.
• Users will no longer be able to connect or access personal accounts within OWA.
• Users will need to manage personal and work calendars separately.
• Events may need to be manually coordinated across calendars.

In short, this prevents users from adding personal accounts in the Outlook Web App, strictly separating work and life. While this sharpens the app’s professional focus, users who rely on a unified view must now manage their personal schedules externally.
