How can I recover all my missing calendar events

Hi Helen,

Thank you for reaching out to Microsoft Q&A forum. I understand how important it is to recover your lost Outlook calendar events. Based on your description and the data I’ve gathered, here are some steps to help you recover your calendar entries:

1. Check Visibility and Filters

• In Outlook Web or App, go to your calendar view settings.
• Ensure no filters are hiding events (e.g., category filters, date range limits).
• Switch to “Month” view to see a broader range of dates.

2. Search for Events

• Use the search bar in Outlook Calendar to look for specific event titles or keywords.
• Expand the search scope to include all folders.

3. Recover Deleted Items

• Go to the Deleted Items folder in Outlook.
• Look for calendar events and right-click to Restore them.
• If not found, use Recover Deleted Items:
  • Go to the “Folder” tab > “Recover Deleted Items.”
    • Select missing events and click Restore Selected Items.

4. Check Sync Status

• Ensure your Outlook account is syncing properly across devices.
• Manually trigger a sync in Outlook Mobile and Desktop.
• Restart the app or device if needed.

5. Restore from Backup

• If you have a backup of your Outlook data (.pst file), you can import it:
  • File > Open & Export > Import/Export > Import from Outlook Data File (.pst)

If the issue persists, please let me know. I’ll be happy to guide you further or escalate the issue if needed.

Dear Helen,

Thank you for your thoughtful follow-up and for taking the time to work through the suggestions I shared earlier. I truly appreciate your persistence. I'm glad to hear that your calendar is now syncing between your computer and iPhone, and that you're becoming more familiar with the Outlook environment.

Since you weren’t able to locate a “Recover Deleted Items” option or any deleted calendar entries, here are a few additional steps we can try:

1. Check Calendar Folders

Sometimes events are moved to a different calendar. In Outlook:

• Go to the Calendar view.
• On the left pane, ensure all calendars (including shared or secondary ones) are checked.
• Look under “My Calendars,” “Other Calendars,” and “Shared Calendars.”

2. Use Outlook Web Access (OWA)

Sometimes the web version shows more recovery options:

• Visit https://outlook.office.com/calendar
• Try searching for events using keywords or dates.
• Check the “Deleted Items” folder from the Mail view, then click “Recover items deleted from this folder” at the top.

3. Check for Rules or Filters

It’s possible that a rule or sync setting moved or deleted calendar items:

• In Outlook desktop: Go to File > Manage Rules & Alerts (Classic version) or Settings > Mail > Rules and review any active rules.
• Also check filters in the Calendar view to ensure no filters are hiding events.

4. Outlook Mobile App Settings

On your Phone:

• Open the Outlook app > Tap your profile icon > Settings > Tap your account.
• Try removing and re-adding the account if syncing still seems inconsistent.

5. Microsoft Support Recovery Tool

• If none of the above work, Microsoft has a support tool that may help recover lost calendar data:
  Go to Contact - Microsoft Support: Contact - Microsoft Support
• In the search box, type "calendar issues" or "recovery calendar" and press Enter.
• Scroll down and select the "Contact Support" or "Sign in to contact support" option. You can sign in using any other accessible email address you have.
• For "Product and services", select Microsoft 365 and Office.
• For "Category", select Manage my profile information.
• You should then see the option to "Chat with a support agent in your web browser".

Dear Sin-D. Thank you for all your suggestions! After a few hours on the outlook app - the calendar events I put in did sync between the outlook on my computer and my iPhone. I was able to get through most of your suggestions and became acquainted with this huge outlook program. I never used this program before so it took hours to find most of what you were referring to. I have only used outlook on my iPhone for emails, contacts and calendar. I was able to find emails from years ago I don’t remember if they were deleted or just not visible anymore on a daily basis. I could not find a folder that had deleted calendar entries or anyplace that said “ recover deleted items” in all folders. My calendar events are still missing. I do not have a backup folder. I am wondering why all my emails are there but my calendar events are not. It seems to be the only part of outlook that is not working. Any help you can give me going forward to retrieve my calendar would be greatly appreciated. I have no idea where I am supposed to be except for reminders from e-mails. Thank you and good night !
