Missing files

I use emClient since 2023 and upgraded in July 2024.

Some days ago, I migrated my personal email account from one host to another.

To prevent loss of data I transferred my emails and folders within emClient to my Gmail account. Thus, the emails and files were uploaded to Gmail.

After the migration to the new host was completed, I transferred all the folders and emails back to my personal account (which was now connected to the server of the new host).

However, emClient did not copy all the files and showed many error messages that folders could not be created. These folders did not contain any special letters or numbers etc.

As of today, many emails are still missing.

Any help would be greatly appreciated.
