This article documents the limits and constraints that apply when using the Salesforce Help Portal, also known as the Help & Training (H&T) portal. Understanding these limits helps Help & Training (H&T) Administrators and Primary Case Contacts manage cases, collaborators, and file attachments effectively. These limitations are set by design and cannot be modified by customers or administrators.
The following limitations apply to the Salesforce Help Portal.
A maximum of 20 collaborators can be added to a single case. Each collaborator must have previously logged in to Salesforce Help in order to be eligible for addition.
Users permitted to add case collaborators: Primary Case Contacts and Help & Training Administrators. Help & Training Administrators may add themselves and any of their organization's other valid users in the Salesforce Help site as a collaborator on a case they do not own.
Maximum number of files attached to one case: 10
Maximum file size of a single attachment: 4.2 MB
Supported file types include: PDF, TXT, image files, as well as ZIP, DOC, MPEG4, 3GPP, MOV (h264 and MPEG4 video codecs; AAC audio codec), AVI (MJPEG video codec; PCM audio), GTM (GoToMeeting recordings), WMV, FLV, XLS (including .xlsx and .xlsm), PPT (including .pptx and .pptm), WMA, MPEGPS (MPEG2 video codec; MP2 audio), and WebM.
Supported login types for Salesforce Help access: Salesforce (force.com org) and Marketing Cloud.
Access to the Help Portal depends on the type of License assigned to the user. Users of other Salesforce services — such as Social Studio, Radian6, and Pardot — do not have direct access to the Help Portal using those products' credentials. If you have access to a Salesforce or Marketing Cloud login, use one of those to log in to the Help & Training portal.
