Microsoft Outlook add-in change request - outlook

I have developed an outlook add-in and posted on Microsoft appstore.
But I got validation error report with change request as below:

Outlook add-in with React not visible for shared mail box

We have created an Outlook add-in to move emails/attachments to SharePoint which works fine for user mailbox but when I move to the shared mailbox the add-in is not visible
Inside get add-ins to tab the add-in is visible but not visible on the ribbon.
We have configured shared mailbox in Exchange and is auto mapped to outlook. The SupportsSharedFolders is set to true and there are no issues while installing the manifest.
Did I miss any step in configuration?
Please help to get the add-in started for the shared mailbox.
EDIT: Im including the manifest file below. Just found that the desktop client is using version override 1.0 and Web and mobile are using version override 1.1.

outlook add-ins on safari and chrome on mobiles

Given that outlook for iOS and android only supports "MessageReadCommandSurface" I thought I'd investigate how my add-in looks on safari and chrome running on a mobile. On all other platforms I can see'Send to OneNote' as well as my own app but on mobile i only get 'My Templates'. My add-in doesn't appear. Am i doing something wrong?

Outlook Add-In Icon Not Showing

Outlook Add-in not rendering in 2016

I am creating an Outlook Add-in, which works perfectly fine in Outlook 2013. In Outlook 2016, however, nothing shows up. The ribbon items are completely gone. In 2013, there are three ribbon buttons that show up, that do not in 2016.
Any ideas what might be wrong in the manifest file.

Inside the <Supertip> tag there are <Title> and <Description>. The <Title> resource must be placed into <bt:ShortStrings> parent tag. In the same time the <Description> resource must be placed into <bt:LongStrings> parent tag.
Documentation on Office Add-ins XML manifest stated the following:
Title: Required. The text for the supertip. The resid attribute must be set to the value of the id attribute of a String element. The String element is a child element of the ShortStrings element, which is a child element of the Resources element.
Description: Required. The description for the supertip. The resid attribute must be set to the value of the id attribute of a String element. The String element is a child element of the LongStrings element, which is a child element of the Resources element.
To fix your manifest I have moved the following Resource Ids into <bt:ShortStrings> ...
<bt:ShortStrings>
<bt:String id="groupLabel" DefaultValue="--REMOVED--"/>
<bt:String id="msgReadPaneButtonLabel" DefaultValue="Open --REMOVED--"/>
<bt:String id="menuCreateLabel" DefaultValue="Create New"/>
<bt:String id="menuSettingsHelpLabel" DefaultValue="Settings and Help"/>
<bt:String id="createContactLabel" DefaultValue="Contact"/>
<bt:String id="createFirmLabel" DefaultValue="Firm"/>
<bt:String id="createOpportunityLabel" DefaultValue="Opportunity"/>
<bt:String id="createActivityLabel" DefaultValue="Activity"/>
<bt:String id="checkAccountInformationLabel" DefaultValue="Account Information"/>
<bt:String id="checkHelpLabel" DefaultValue="Help"/>
<bt:String id="msgReadPaneButtonTitle" DefaultValue="--REMOVED--"/>
<bt:String id="menuCreateTitle" DefaultValue="Create New"/>

<bt:String id="checkHelpTitle" DefaultValue="Help"/>
<bt:String id="checkAccountInformationTitle" DefaultValue="Account Information"/>
<bt:String id="createActivityTitle" DefaultValue="Create New Activity"/>
<bt:String id="createFirmTitle" DefaultValue="Create New Firm"/>
<bt:String id="menuSettingsHelpTitle" DefaultValue="Settings and Help"/>
<bt:String id="createContactTitle" DefaultValue="Create New Contact"/>
</bt:ShortStrings>
EDIT:
This is become "remote debugging" instead of QandA, but I already done it anyway. After take a closer look on your manifest and replacing all image entries with my own I realize you are missing entire <Resources> section in your <VersionOverrides> element. You must have this tag inside VersionOverrides element. As long as I added the section the add-in appeared in Outlook Desktop. Please note, the resource strings in VersionOverrides element will override the same strings in the parent element.

How to show addin in Outlook when composing mail?

I used office-generator to scaffold out an Outlook addin and it seems to show up and run when mail opened in read mode but its not showing up in the addins section when a new mail is being composed. I wanted to show the addin to show up in compose mode and once clicked open the addin in pane.

This is handled in the VersionOverides section. In the manifest you included, you'll notice an ExentionPoint defined as <ExtensionPoint xsi:type="MessageReadCommandSurface">. This defines an extension point for Message Reading.
To enable the add-in during Compose you'll need to add an ExtentionPoint for MessageComposeCommandSurface.
If you would like to only show during Compose, simply remove the MessageReadCommandSurface section. The same applies to AppointmentAttendeeCommandSurface (reading appointments you were invited to) and AppointmentOrganizerCommandSurface (reading appointments you created).
