Symptoms

When trying to migrate, or running a pre-check on a file from Microsoft 365, you receive the following error message:

The folder name 'FOLDER_NAME' contains one or more special characters (e.g. '#' or '%') that prevent Sharegate from fetching its files. Renaming the folder to remove these characters will allow Sharegate to copy its content.

Error code

AN-116-018

Details

This issue stems from the Microsoft API and there is no workaround at this time. This only applies specifically to files migrated from a Microsoft 365 source.

Solution

You will need to rename the folder to remove the problematic special characters, and run the migration or pre-check again.
