Addin installation failed after updating with code for mobile integration #5380

DunhamGitHub · 2025-01-20T17:05:29Z

How to debug not being able to load Outlook Addin with mobile code (desktop version can be added)? I do not see any feedback in the Console!?

Sideloading my (demo) DESKTOP .xml Manifest works, after updating it for MOBILE it does not! (Manifest files attached as reference)

outlook-manifest_mobile.zip

I have updated it with the snipped from: https://github.com/OfficeDev/office-js-docs-pr/blob/main/docs/outlook/add-mobile-support.md.

When I am trying to add it (in Outlook Web) I get an error,

How to determine the reason for failure?

Hi @DunhamGitHub,

Thanks for reporting this. @samantharamon could you please help investigate?

samantharamon · 2025-01-31T01:21:53Z

Hi @DunhamGitHub,

Thank you for reaching out. Your add-in's manifest needs to specify the VersionOverrides 1.1 element to use <MobileFormFactor>. While it's mentioned in Add support for add-in commands in Outlook on mobile devices, I understand that it isn't immediately obvious in the code snippet, so I created PR OfficeDev/office-js-docs-pr#5014 to clarify this. Here's an updated version of your snippet.

<VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides" xsi:type="VersionOverridesV1_0">     
    <VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides/1.1" xsi:type="VersionOverridesV1_1">
        ...

                <Group id="mobileMsgRead">
                    <Label resid="GroupLabel" /> <!-- I updated this to match the label ID in the Resources section. -->
                    <Control xsi:type="MobileButton" id="msgReadCreateSO">
                        <Label resid="ButtonCreateSO.Label" />
                        <Icon xsi:type="bt:MobileIconList">
      	                    <bt:Image size="25" scale="1" resid="ribon-icon-25" />
                            <bt:Image size="25" scale="2" resid="ribon-icon-25" />
      	                    <bt:Image size="25" scale="3" resid="ribon-icon-25" />

	                    <bt:Image size="32" scale="1" resid="ribon-icon-32" />

	                    <bt:Image size="32" scale="3" resid="ribon-icon-32" />

	                    <bt:Image size="48" scale="1" resid="ribon-icon-48" />
	                    <bt:Image size="48" scale="2" resid="ribon-icon-48" />
	                    <bt:Image size="48" scale="3" resid="ribon-icon-48" />
                        </Icon>
                        <Action xsi:type="ShowTaskpane">
 	                    <SourceLocation resid="readTaskPaneUrlMobile" />
                        </Action>
                    </Control>
                </Group>
            </ExtensionPoint>
        </MobileFormFactor>
        ...
    </VersionOverrides>
</VersionOverrides>

I also noted that the resid value of the group label in the <MobileFormFactor> element isn't defined in the <Resources> section. Updating the value to GroupLabel (or a new string of your choosing) should do the trick.

Let me know if you still continue to run into issues when sideloading.

DunhamGitHub · 2025-02-03T05:12:06Z

Thank you for your reply. I have made the changes. I get "failed" as return.

a) Am I correct in assuming that there is 0 feedback as to why the addin installation fails? (Also not in the Console)

b) In your example code you put <VersionOverridesV1_0"><VersionOverridesV1_1">. So VersionOverrides 1_1 is a child of 1_0?

c) Updates .xml below (I have the <VersionOverrides 1_0 /><VersionOverridesV1_1 /> on the same level):

a) Am I correct in assuming that there is 0 feedback as to why the addin installation fails? (Also not in the Console)

While the dialog that appears when attempting to sideload the add-in doesn't provide additional feedback, you can use the options in Validate an Office Add-in's manifest to verify your manifest.

b) In your example code you put <VersionOverridesV1_0"><VersionOverridesV1_1">. So VersionOverrides 1_1 is a child of 1_0?

That's correct. For more information, see VersionOverrides 1.0 element in the manifest file for a mail add-in.

c) Updates .xml below (I have the <VersionOverrides 1_0 /><VersionOverridesV1_1 /> on the same level):

Integrating the sample code I provided with the rest of your manifest, I'm able to install the add-in. If you haven't yet, try closing your current browser window and opening a new window before attempting to install your add-in.

Thank you for your updated example. I was able to side-load this successfully.

However, the Addin does not show up in the iOS Outlook version, what is missing?**

samantharamon · 2025-02-06T19:42:46Z

I'm able to see the Digital WorkMate add-in in Outlook on iOS and on Android. If you haven't already done so, please try restarting the Outlook app on your device. If you have multiple accounts, please make sure that you're also accessing the add-ins for the account to which the add-in was sideloaded.

Hi. 4 days have passed, I have restarted (in that time) the app and the iPhone (15 Pro) multiple times.
-> The Addin does not show up in the Outlook app (latest iOS, latest Outlook app), however the Addin is still visible in the normal web-browser of the same account.

Here is an email in the web-browser (Addin visible):

Here is the same email in the Outlook iOS app (Addin NOT visible):

Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

The issue with the Add-in manifest validation failure on Microsoft 365 admin center with the Extension point MobileLogEventAppointmentAttendee has been fixed. It is now possible to install the manifest through the M365 Admin Center. Please ensure that your manifest is updated and try again.

Thanks for the update, @DunhamGitHub.

@exextoc could you please investigate this further?

DivyaPatidar · 2025-02-13T08:08:03Z

@DunhamGitHub
Could you please check the following:

Do you see any add-ins on the iOS app?
Can you uninstall the add-in and reinstall it from the Outlook app on iOS, then check if the add-in shows up?
Do you see this add-in on any other platform, such as Outlook Classic on Win32, Outlook on Mac, or Outlook on Android?
Can you check if the Optional Connected Experiences setting is enabled on your iOS device? For more details, please refer here
If none of this helps, please collect logs as mentioned here and share the diagnostics ID.

Hi

No (see my screenshot of the iOS Outlook App displaying no available Addins
No (I cannot reinstall it from the Outlook app on iOS) because the Addin a) does not show up ( see 1) ) and b) the Addin is sideloaded (can't do that on iOS AFAIK).
I do not have Windows (Outlook Classic), not Outlook on Mac, not any Android devices.
I am using Outlook online, how would I check if "the Optional Connected Experiences setting is enabled on your iOS device"?

anjalitp · 2025-02-18T16:40:10Z

@DunhamGitHub To enable 'Optional Connected Experiences' on an iOS device, go to Settings -> Privacy. Turn ON this setting, then relaunch the Outlook app and check if the add-ins show up

If add-ins are still not available in Store, please gather the logs from iOS device(where the add-in is not working) and Outlook Web(where the add-in is working) by following the steps here

That works! The Addin does show up on Outlook iOS.
