Optimizing PowerApps: Managing Multiple Email Addresses and SQL Date Range Filtering


Efficient SQL Date Range Filter for Email Addresses Management in PowerApps

In the realm of data management, there often arises the need for efficient methods to handle multiple email addresses in a single field. This tutorial provides a comprehensive guide on managing multiple email entries using PowerApps, while primarily focusing on SQL date range filtering. Should you face any challenges or need further technical assistance, don’t hesitate to contact us.

Storing Multiple Email Addresses in SharePoint

When developing a data entry screen to handle multiple email addresses in a field, a semi-colon-separated list is an efficient way to store these addresses in a SharePoint list. This post offers insights into the configuration of a combo box control that aids in both the entry and display of these addresses, connected via the Office365 connector. The connector further allows for the combo box to exhibit email addresses of all members of an organization.

Data Structure Overview

To illustrate, consider creating a form facilitating users to compile an email distribution list. The essential data source for this demonstration would contain a column titled ‘EmailRecipients’. This column will be designed to hold a semi-colon separated list of email addresses. Building an auto-generated app based on this list is the starting point, with the integration of the ‘Office365Users’ data source being a vital requirement.

Configuring ComboBox for Office 365 Email Addresses

Within the edit form, the default text input control in the ‘EmailRecipients’ card should be replaced with a combo box control. Rectifying references stemming from the deleted text input control is pivotal. By setting the items property of the combo box to:


we can enable the combo box to show matching email addresses based on user input. With the SelectMultiple property value retained as true, multiple email address entries can be facilitated.

Saving and Retrieving Email Addresses

For the form to save email addresses correctly, update the card property with:

Concat(cboUsers.SelectedItems, Mail & ";")

Similarly, to display existing email addresses, the DefaultSelectedItems property of the combo box should be set as:

RenameColumns(Split(ThisItem.EmailRecipients, ";"), "Result", "Mail")

With these settings, the app will be primed to save and retrieve multiple email addresses using a combo box.

Power Apps SQL Date Range Filter Technique

To further enhance the functionality of your app, consider employing SQL date range filters. This section highlights a technique to avoid delegation issues by using variables to filter a date range. We’ll focus on filtering a table to show dates within a predetermined number of months. As an example, the ‘Calendar Dates’ SharePoint list comprises consecutive dates ranging from 1/1/2018 to 12/31/2024.

Optimized Date Range Filtering

While the WITH function has its advantages, it does present delegation constraints. This results in limitations on the number of displayed results. To mitigate this, set the StartDate and EndDate variables before employing them within a filter function. This delegation-friendly code ensures a more efficient execution when filtering date ranges.


Handling multiple email addresses within a single field is made seamless by storing them as a semi-colon-separated list. Leveraging a combo box control in PowerApps allows for efficient entry and display of these addresses, making data management more streamlined.
