A Chatter private group is a type of Chatter group that allows members to share feedback and ideas with each other in a secure and exclusive space; only members can see and post in a private group. It can be used by Ursa Major Solar to create a space for product owners to collaborate with just the product team by creating a Chatter private group and adding product owners as members. Using quick actions to log communication, configuring a Chatter public group, or adding activity history to document tasks are not solutions for creating a space for product owners to collaborate with just the product team; they either do not provide privacy or do not support collaboration.

One of the possible causes for being unable to add a new user in Salesforce is that the username is already in use by another organization. Usernames must be globally unique across all Salesforce orgs, so if another user has claimed that username before, it cannot be used again. To fix this issue, choose a different username that is not taken by anyone else. The username is not restricted to a domain specific to my domain unless specified by an administrator. The email address used for the username does not have to match a contact record. The email used for the username can be any valid email address.

Permission sets are a flexible way to grant additional access to users without changing their profiles. To provide access to the lead object for a team of support users, create a permission set that includes the appropriate object and field permissions for leads, and then assign it to the users.

Themes are a way to customize the look and feel of Salesforce by changing the colors, images, and logos that appear on Lightning Experience pages. However, there are some limitations and considerations when using themes, such as: only one theme can be active at a time, and a theme applies to the entire org; themes apply only to Lightning Experience and do not affect Salesforce Classic or the Salesforce mobile app; up to 300 custom themes can be created, modified, or cloned from the built-in themes; Chatter external users see the built-in Lightning theme only and cannot see custom themes.

Currency locale and default language are two of the company settings that an administrator can configure in Salesforce. Currency locale determines how currency amounts are formatted and displayed in reports and other places.
