Kablink Vibe lets you add files and entry attachments to the Vibe site via email, as described in Adding Entries to a Folder Via Email
in the Kablink Vibe 4.0.1 User Guide. However, if you have met your data quota, you are unable to email entries to Vibe if they include attachments.
If you have exceeded your allotted data quota, you should purge the items that you have previously deleted, as discussed in Section 13.8, Making Disk Space Available by Deleting Items from the Trash.
