Error C407: Saving in the cloud failed
You're working with a cloud project. Citavi could not save your most recent changes in the cloud.
If you want to save a project in the cloud for the first time and error C407 appears, there are several causes that could be to blame:
▪The project contains a large number of categories
▪Lists (Persons and organizations, journals, etc.) contain duplicate entries
▪Special causes that can only be ascertained by examining the project
If your project contains a large number of categories, follow the steps in this FAQ article.
If you suspect that the problem is being caused by duplicate entries, follow the steps in this FAQ article.
Otherwise, send the project file that you could not upload to the Citavi Support team. Make sure to send only the .ctv5 or .ctv6 file without the Attachments folder. Use our special upload form and enter the error message in the Message field.
If the project was already saved in the cloud once but still displays error 407, invite a member of the Citavi Support team to the project so that they can troubleshoot the problem. Make sure to also write an email to the support team.
Please send the error message and the OperationID to the Citavi Support team.
