COHO Cloud empowers you to send, share, collaborate, and publish most common types of files, such as pictures, documents, PDF files, and web content. However, some unusual types of files are not allowed as Cloud Mail or Office 365 (Exchange) attachments, Cloud Websites uploads, or SharePoint files. These types of files are potentially unsafe because they may contain software designed to harm computers or compromise your privacy. Cloud Drive does not restrict files by their extension.
Cloud Mail and Outlook Web Apps, and Cloud Websites will notify you if a file you attempt to upload or attach is not allowed. If you send (using an app or device) or receive an email message with one of these types of files, it might not be delivered, or the attachment may be removed automatically.
The following file types are not allowed by one or more COHO Cloud services:
