When the add-in Outlook manifest updates(for example increase version), will it automatically bring it to users? Does Microsoft have any documents for this?

Hi @ChristyZhang-MSFT , Thank you for your reply.Is there any difference between add-in in store and add-in install by file/url? when I update the manifest file, will the add-in install by file/url automatically update or do we need to reinstall it?

Hi @Dino ,

Thanks for your reply!

Is there any difference between add-in in store and add-in install by file/url?

Yes, there is a difference between add-ins installed from the store and those installed by file/URL.

When you install an add-in from the store, it is automatically updated by Microsoft, and you can manage it from the Office Add-ins dialog box. You can also browse the store to find other add-ins to install. On the other hand, when you install an add-in by file/URL, you have to manually update it, and it is not managed by Microsoft. You can install add-ins by file/URL from the Office Add-ins dialog box.

when I update the manifest file, will the add-in install by file/url automatically update or do we need to reinstall it?

As i know, if a developer updates something in the manifest, the version must be incremented as well. This way, when the new manifest is installed, it will overwrite the existing one and the user will get the new functionality. If this add-in was submitted to the store, the new manifest will have to be re-submitted and re-validated. Then, users of this add-in will get the new updated manifest automatically in a few hours, after it is approved.

If the add-in's requested permissions change, users will be prompted to upgrade and re-consent to the add-in. If the admin installed this add-in for the entire organization, the admin will have to re-consent first. Users will be unable to use the add-in until consent is granted.

In addition, i found the below information in this article:

When you add features or fix bugs in your add-in, you'll need to deploy the updates. If your add-in is deployed by one or more admins to their organizations, some manifest changes will require the admin to consent to the updates. Users will be blocked from the add-in until consent is granted. The following manifest changes will require the admin to consent again.

Changes to requested permissions. See Requesting permissions for API use in add-ins and Understanding Outlook add-in permissions.

Additional or changed Scopes. (Not applicable if the add-in uses the unified manifest for Microsoft 365.)

Additional or changed Outlook events.
