Question

Word Add-in inconsistently visible to users after Centralized Deployment

Hello Microsoft Support,

Any recommended troubleshooting or sync steps to ensure consistent visibility for all usersHello Microsoft Support, We are experiencing inconsistent behavior after deploying our Word Add-in through Centralized Deployment in Microsoft 365. The add-in does not appear uniformly for all users — it shows up for some users immediately, while others don’t see it at all, or it appears randomly after several hours or the next day. Below are the details and questions for your investigation:
1. Inconsistent Reflection:
  - After deployment, some users can see and use the add-in right away, while others (in the same group or license type) cannot.
  - It seems to reflect randomly without a clear pattern.
2. Deployment Propagation:
  - What is the expected time for add-in propagation across all users after Centralized Deployment?
  - Are there any known caching or background sync delays in Word Online or Desktop clients?
3. License / Policy Dependencies:
  - Could licensing, Azure AD sync delay, or user token caching cause this behavior?
  - Does each user need to reload Word or sign out/in to refresh deployment visibility?
4. Dialog / Taskpane Issue:
  - For users where the add-in appears, sometimes the dialog or taskpane doesn’t open when clicked.
  - What logs or diagnostic methods (Office.js logs, browser console logs) can we provide to help debug this?
Environment Details:
- Platform: Microsoft 365 (Centralized Deployment)
- Add-in Type: Word Add-in (Office.js)
- Affected users: Some users in the same group, random visibility
- Add-in Deployment: Admin Center → Integrated Apps → Centralized Deployment
- Manifest Version: [Insert version]
- Office Client: Word Desktop + Word Online
- Tenant: [Insert tenant or org name if applicable]
Expected Outcome:
The add-in should appear consistently for all assigned users shortly after deployment and the dialog should open reliably. Request:
Please advise on:
- The typical propagation time for centralized deployments
- Known caching/visibility delays
- Any recommended troubleshooting or sync steps to ensure consistent visibility for all users

Hi @Piyush Ambaliya

Thank you for reaching out to the Microsoft Q&A forum.

According to Microsoft documentation, it can take up to 24 hours for a newly deployed add-in to appear for all assigned users, and up to 72 hours for updates or changes to be fully reflected across all users.

If some users still do not see the add-in after this period, please review the following official checks from Microsoft:

Run the Centralized Deployment Compatibility Checker to confirm that affected users have valid Microsoft 365 licenses and are correctly configured in Exchange Online.
Verify that the add-in is assigned only to top-level groups. Centralized Deployment does not support nested group assignments.
Confirm that the affected users are signed in with the same organizational account that was included in the deployment.
Check whether the add-in has been fully installed by searching for its GUID in the %LOCALAPPDATA%\Microsoft\Office\16.0\Wef\ folder.

For users who can see the add-in but cannot open its dialog or task pane, you can enable “Show add-in user interface errors” from File > Options > Advanced > General, then sideload the add-in again to view any UI-related error messages.

I hope you’re doing well.

Thank you @Dora-T for your quick response and for providing useful information.

However, I would like to highlight that the issue still persists — sometimes the add-in loads quickly, but other times it does not load at all after centralized deployment, even after performing all troubleshooting steps and clearing the cache.

Additionally, the add-in features are not stable in the latest version of Microsoft Word. For example:

When clicking the Add-in button, a blank page sometimes appears. 2.In some cases, it loads an older layout instead of the updated version.

Could you please help identify the root cause or provide any recommended steps to ensure consistent add-in performance across all users?

Hi @Piyush Ambaliya

Thank you for your response.

I'm sorry to hear that the issue persists and that the add-in’s behavior remains inconsistent. At this time, I’d like to take a bit more time to review available documentation before sharing further guidance.

As for your request for a root cause analysis, please note that this forum is not Microsoft support; it is a form of users' mutual support. Forum members don’t have access to your account and can only provide general recommendations. Therefore, I’m unable to conduct in-depth investigations or provide a formal Root Cause Analysis (RCA). I can only offer information based on publicly available documentation and my personal knowledge.

Unfortunately, neither I nor the Microsoft 365 subscription support team are able to offer direct support for this specific matter.

Support limitations for issues with Microsoft 365 Apps - Microsoft 365 Apps | Microsoft Learn

So, if you require a detailed RCA or more comprehensive support, I would recommend evaluating Microsoft Unified Support. You can find more information and explore this option at the following link: Microsoft Unified Overview | Microsoft Unified

Thank you again for your patience and understanding.

Hi @Piyush Ambaliya

Thank you for your patience while I reviewed this further.

I’ve reviewed the available Microsoft documentation and related cases, but there isn’t any additional public guidance or confirmed information beyond what has already been shared. I completely understand how inconvenient this situation can be, and I truly appreciate your time and effort in performing the suggested troubleshooting steps.

At this stage, since no further official documentation or fixes are currently available, I would recommend considering Microsoft Unified Support if a detailed analysis or escalation is needed. This would allow Microsoft engineers to review your tenant configuration and logs directly.

Thank you again for your understanding and for taking the time to share your issue.
