Unsupported file extensions that would be beneficial - Intercom Attachments

Hello all, 

On behalf of the Access LMS Support team, it would be beneficial to have the following file formats enabled to be used in Attachments on the Intercom Chat window:

.mpg, .webm, .webp, .tiff, 

.docx, .txt, .rtf, .pptx, .ppt

 

This is to ensure our clients will be able to share materials that demonstrate a specific area of the system, in order to facilitate a better and faster service to them.

Thank you all in advance!

Hey ​@Andrei Froni,

You can allow most of these in the Messenger via Settings → Workspace → Security → Attachment settings. Turn on “Allow other file types” and add: .mpg, .webm, .tiff, .docx, .rtf, .pptx, .ppt (and .txt is supported by default).

.webp is permanently blocked and cannot be enabled.

You can check out this article for more info as well as a list of file types that cannot be enabled.
