What's fixed

Migrations from source files that contained special characters could, in some very specific cases, cause the migration to override newer files at the destination.

There would be a site column error when importing a OneNote Notebook from a file share to Microsoft 365 in Normal mode.

You could not select a subsite when running an External sharing report in Security.

Files that had a name that started with a period (.) would have the period replaced by an underscore (_) when running an Import from a file share to Microsoft 365.
