2. Power Apps & Office 365 Groups
What is covered?
 List owned groups
 List group members
 Check membership
This is a concept how to use Office 365 groups to
show/hide content like buttons or navigation
menus in Power Apps.
It makes it easier for non-developers to manage
permissions for Power App content.
Permissions of the logged in user in the app are
defined by the membershipin an Office 365 Group.
Connected Data Sources
 Office365Groups
 Office365Users

3. Remarks
This presentation describes how to get information
about Office 365 Groups and list the members of a
group.
If this scenario is used in a productive application
the developer would get the ID of the group and
check directly the membership OnStart or on the
Home screen.

4. List my Groups
Items = SortByColumns(
Office365Groups.ListOwnedGroupsV3().value,"displayName",Ascending)
// To keep some data in variables and collections for later use
OnSelect = Set(glb_selO365Group,ThisItem.id);
// The email address of the selected O365 group
Set(glb_selO365GroupMail,ThisItem.mail);
// Storing all members and details in a Collection
ClearCollect(collMembers, Office365Groups.ListGroupMembers(g_MyGroups_1.Selected.id)
.value);
// Concatenate all email addresses, so I can email the members directly
Set(glb_MailIndividuals,Concat(collMembers,";" & mail))

5. List Group Members
 Add a List box and display the Members:
Items = Office365Groups.ListGroupMembers(glb_selO365Grou
p).value
 Add a text field and display the concatenated emails
Text = glb_MailIndividuals
// Both variables glb_selO365Group and
glb_MailIndividuals have been set in the previous slide

6. Check Membership
 Add a Combobox to select a user
OnChange = Set(glb_selUser, cbx_SearchUser.Selected.Mail)
 Add a text label to display the email address (optional)
Text = glb_selUser
 Add an image control
If(
IsBlank(
Find(glb_selUser, glb_MailIndividuals)),
'Thumbs-Down',
'Thumbs-Up'
)

7. Summary
 Create Office 365 Groups for each permissionyou want to use in a Power App
 Add your users to the desired groups
 In Power Apps check to which group the currently logged in user belongs to
 Use this information to hide/display controls like buttons or navigation menus
