Dear @Emily Dishian,

Good day, and thank you for providing a detailed description of the issue you’re experiencing.

From my research, newly provisioned Windows 365 Cloud PCs often start with a fresh Outlook profile using Cached Exchange Mode (the default). During the initial sync, Outlook typically downloads only a limited amount of recent mailbox data, commonly the last 1 to 3 months for performance reasons. Older calendar events still exist in your Microsoft 365 mailbox but haven’t yet been pulled into the local cache on the Cloud PC.

To ensure that your Cloud PC displays your full calendar history, please try the following steps.

1.Switch to Online Mode (immediate access to full history)

• Open Outlook (classic) on the Cloud PC (If Outlook opens in the new Outlook experience, use the toggle in the top‑right corner to switch back to classic Outlook.)
• Go to File > Account Settings > Account Settings.
• Select your Microsoft 365 / Exchange account > Change.
• Uncheck Use Cached Exchange Mode.
• Click Next > Finish > Restart Outlook.

2.Stay in Cached Exchange Mode but expand the sync range

If you prefer to keep Cached Exchange Mode enabled, you can force Outlook to sync more historical data.

• Go to File > Account Settings > Account Settings > select your account > Change.
• Under Offline Settings, move the slider all the way to the right (All) or set it to the maximum available (e.g., 36 months or more).
• Click Next > Finish > Restart Outlook.

3.Reset the Calendar View and Clear Any Filters

• In Outlook Calendar, go to the View tab > Current View > Reset View (or View Settings > Filter > Clear All).
• Switch between Month, Week, and Day views and use the mini-calendar on the left to scroll back to older months/years.

4.Check in Outlook on the Web 

This helps confirm that the data itself is present in the mailbox.

• Go to outlook.office.com (or office.com) and sign in with the same account.
• Open Calendar and scroll back using the left-side date picker.
• If the full history appears here, the issue is local to the Outlook profile on the Cloud PC.
