Office add-in deployment within integrated apps: eligibility error with the Centralized Deployment

Question

Hi,

We have outlook add-in deployed via centralized deployment in

"Microsoft 365 admin center > Settings. > IntegratedApps". For some time it was there and it worked.

1. We went to update manifest file, this update didn't take any effect.
2. Then we deleted add-in app and tried to install again, it says deployment fail.

3 . Tried to deploy in another way via "Adminportal/Home/#/Settings/AddIns" and got:

This operation was unsuccessful - reasons may include:

 (3ec53d9a-1ac1-46d9-9646-6b106f0a2c79)

This is blocking us, seriously, any help with this is much appreciated.Thank you in advance.Best Regards, Ante

Answer 1

Hi @Ante Kotarac,

Thank you for posting to Microsoft Community.

Based on your description, I understand you got an error message about eligibility requirements when you deployed add-in.

It could be the eligibility requirements have been changed in your environment for some reason.

Therefore, please kindly double check the requirements as links below.

Determine if Centralized Deployment of add-ins works for your organization - Microsoft 365 admin | Microsoft Learn

Also, please refer to steps of Deploy add-ins in the admin center - Microsoft 365 admin | Microsoft Learn to check if there are anything missing.

Hope it helps and if there is anything else I could help with, please let me know.

Answer 2

It looks like there is an advisory for this issue in the office portal - its MO801142 "Admins may be unable to use certain add-ins from the Microsoft 365 admin center using centralized deployment"Incidentally, this morning I can refresh the add-in from the store without getting the error.

Answer 3

Problem Encountered

Error in the User Interface (UI)

During the deployment process, the following error message was displayed:

This operation was unsuccessful - reasons may include: (12345678-1234-1234-1234-123456789abc)

Error in the Backend Request

Upon analyzing the logs, I found the following error:

{ "appsManagementStatus": [ { "appId": "abcd1234-abcd-1234-abcd-123456abcdef", "workload": "WXPO", "status": "Failed", "commandType": "Deploy", "errorReason": "Error while processing app management request for efgh5678-efgh-5678-efgh-56789abcdef0 with message = {"ResponseResult":"FailedWriteToExchange","ResponseResultDetails":{"Code":"FailedWriteToExchange"},"ErrorMessages":null}..." } ] }

The error indicated an issue related to writing to Exchange:

FailedWriteToExchange

Steps to Resolve

Connect to the Portal via PowerShell

I started by connecting to Exchange Online to investigate further:

Connect-ExchangeOnline

Check Installed Applications

I listed the installed applications to verify their status:

Get-App -Organization | Format-Table DisplayName, AppId, Enabled, Version

Identify the Root Cause

After further analysis, I discovered that the Office 365 user in question was not located in the correct database on Microsoft's side. This misconfiguration was blocking the plugin deployment.

Migrate the User to the Correct Database

To resolve the issue, I migrated the user to the appropriate database. Here are the commands I used:

Check the user's current database:

Get-Mailbox | Format-List Database, ArchiveDatabase

Create a migration request:

New-MoveRequest -Identity "user@domain.com"

Monitor the Migration

I tracked the progress of the migration using the following command:

Get-MoveRequestStatistics -Identity "user@domain.com"

Reinstall the Plugin

Once the migration was complete, I reattempted the plugin installation, and it worked successfully.
