You can upload your own files and photos to your business mailbox if you are an authorized signatory or have assigned read and write permissions.
How to upload documents:
On the homepage of your business mailbox, look for "Uploads" (Uppladdningar) in the menu.
From there, you can upload your files.
Good to know:

Limitations: You can upload up to 20 files for free. To continue uploading documents after that, you will need to activate Kivra Företag Plus.
