If you have a PST backup created before your calendar data was lost, this method should be your first choice. PST (Personal Storage Table) files are portable, easy to import, and supported by all desktop versions of Microsoft Outlook. Follow the instructions below:
Step 1. Open Outlook (classic) on your computer. Click File > Open & Export > Import/Export.
Step 2. Select Import from another program or file, then click Next.
Step 3. Choose Outlook Data File (.pst) and click Next.
Step 4. Browse to your PST backup file and select how you want to handle duplicates. Click Next.

If you’ve already restored your Outlook data but the calendar is still missing, empty, or incomplete, the issue is often related to view settings, profile conflicts, or sync problems rather than actual data loss. The following checks can help you locate and re-enable your restored calendar.
Fix 1: Set the Restored Calendar as the Default
After importing a PST file or restoring Outlook data files, Outlook may place the calendar in a secondary data file instead of your main mailbox.
Many users think the calendar is gone when it’s simply not selected for display.
Fix 2: Check Calendar View and Filters
Sometimes events are hidden due to view settings:
This can instantly restore the visibility of events that are already present.
Fix 3: Update Folder in Exchange or Microsoft 365 Accounts
If you use a server-based account, your restored data may not appear due to sync errors.
Inconsistent calendars are often caused by incomplete or stalled sync processes.
Fix 4: Rebuild the Outlook Profile
If the calendar still doesn’t appear, the Outlook profile may be corrupted.
A fresh profile often resolves stubborn display and data-loading issues.
Losing your Outlook calendar doesn’t have to mean losing your schedule forever. As long as you made a backup before, you can easily restore Outlook calendar from backup, whether you’re working with a PST file or AOMEI Backupper’s backup image.
