There are several situations for service operations or salespersons going to distant areas where internet access cannot be foreseen or is unavailable, or where signals are weak. We require the agent to employ mobile offline functionality in all of these conditions. This offline feature is only for interacting with customers online (Dynamics 365 Sales, Dynamics 365 Customer Service, and Dynamics 365 Marketing).  

Users sought offline capability as one of the most important features. Offline mobile access is accessible for iOS and Android devices.

A four-step approach will be used to enable Mobile Offline features.

• Enable the table(s) for offline use.
• Set up conflict detection for people who aren’t online.
• Make a profile for your phone that isn’t online.
• Offline access can be enabled in the contemporary powered app.
  

  Activate the table(s) for offline use.

• Select a specific environment in PowerApps.
• Expand the left navigation and select Data from the drop-down menu.
• Select the table that needs to be taken offline from the Tables menu.
• On the right side, click Settings, and the Properties window will open.
• Expand “Offline” under “More Settings.”
• “Enable for Mobile Offline” should be checked.
  

  Configure conflict detection for remote users.

The web (Legacy) app will be used to make these changes. 

• Go to “Advanced Settings” after selecting the environment.
• The web application for D365 will launch.
• Select “Settings” and then “Administration” from the drop-down menu.
• “System Settings” should be selected.
• Check “Enable conflict detection for mobile offline synchronisation” in the “Mobile Client” tab.

Make a mobile offline profile.

We need to construct a mobile offline profile because it specifies a set of tables and users.

• To utilise their mobile device in offline mode, users must have a security role for those table(s).
• Expand “Users + permissions” and choose “Mobile Configuration” after selecting the environment and clicking Settings.
• Either update an existing profile or create a “New profile.” Enter your name and a brief description.
• By choosing Manage or Add a table, you can add a table(s) to the “Data available offline” section.

If you wish to create a link between the Account and Contact tables, for instance, you must first add both tables to the mobile offline account.

Allow offline access to the modern-driven app.

Select Environment and then “environmental URL” to navigate to the environment.

• Go to the Apps section.
• To activate it, select the modern-driven app.
• Click “…” and then “Open in App Designer” after selecting the app.
• Select the Properties option.
• Select the profile and check “Enable Offline Profiles” (s)

Offline restrictions on mobile devices

The instruction will not work offline, even if the button is unhidden via modification.
