When attaching a file in Allmoxy, it's important to set the visibility to "anyone" to ensure that everyone who needs to access the file can do so. By default, the visibility is set to "my company," which restricts access to only those within your organization. To change the visibility setting, simply click on the drop-down menu and select "anyone" before choosing the file you want to attach. This small step can make a big difference in ensuring that everyone who needs to see the attachment can do so, regardless of their location or organization.
