How to Stop OneDrive from Adding Calendar Events to File Names
Question details
Users need to prevent OneDrive from automatically appending Outlook Calendar events to file names upon upload.
- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Uploading scanned photos and business project files to OneDrive.
- Observed behavior
- OneDrive automatically changes the file names of uploaded photos and documents to include Outlook Calendar events, such as holidays, without manual user configuration.
Verify whether you are using a personal or business Microsoft 365 account, as organizational accounts often have hidden background automation policies managed by IT.
Inspect and Disable Power Automate Flows
Identify and turn off any background automation scripts that link Outlook calendars to OneDrive file uploads.
OneDrive does not feature a built-in setting that automatically renames files using calendar events. This behavior is typically caused by a Microsoft Power Automate flow configured to trigger when a new file or scanned photo is uploaded.
Log in to your Microsoft 365 account portal and click on the 'Power Automate' app from the app launcher menu.
Navigate to 'My flows' in the left-hand menu to view a list of all automations currently active on your account.
Look for any flows that mention OneDrive, Outlook Calendar, or file processing/renaming triggers.
Select the responsible flow, click the three-dot menu (More commands), and select 'Turn off' to disable the automatic file renaming.
Contact Your IT Administrator
For business accounts, tenant-level automations might be enforced by your IT department without your direct knowledge.
Switch to WPS Office for a Distraction-Free File Experience
If you are tired of unexpected background automations and complicated file syncing issues in Microsoft 365, consider switching to WPS Office. It provides a lightweight, highly compatible suite for all your document needs without intrusive automated file renaming.
Frequently Asked Questions
Why does OneDrive rename my scanned files with holiday names?
OneDrive does not do this by default. This behavior is typically caused by a background integration, such as a Power Automate flow, that triggers when new photos are uploaded and automatically links them to your active Outlook Calendar events.
Can I stop OneDrive from syncing with my Outlook calendar?
Yes, you can manage connected services by reviewing your Microsoft account privacy and data settings, or by explicitly disabling specific flows in Microsoft Power Automate that bridge your Outlook calendar and OneDrive folders.
Does this file renaming issue affect all Microsoft 365 users?
No, this is an isolated issue often tied to specific business tenants, user-configured automation scripts, or third-party integrations rather than a universal OneDrive feature. Microsoft moderators have acknowledged the behavior and are investigating these edge cases.
