# Groupware: Removing Duplicate Calendar Entries

This source provides technical instructions for removing duplicate and redundant entries within the [[groupware]] calendar module. It addresses issues caused by input errors or synchronization failures.

## Key Instructions
The process for removing duplicates is as follows:

1. Open the **Calendar module**.
2. Click on **Manage** (represented by the gear icon).
3. **Double-click** the specific calendar that contains the duplicates/to be cleaned.
4. Select the option **Remove duplicates** / **Remove duplicate entries** (Doppelte Einträge entfernen) at the bottom.
5. A new tab will open displaying the found duplicates.
6. To execute the deletion, the removal link at the end of the list must be clicked **twice**.
7. Once the list is empty and the page updates, the tab can be closed and the calendar module refreshed to verify the changes.

## Notes
- The process may take some time depending on the volume/number of duplicate entries.
- The requirement to click the removal link twice is a critical step for the operation to complete.
