Restricting users from adding or installing Office add-ins

Question

Hello dear community,

We want to restrict users from adding or installing Office add-ins from the Office Store, but allow one specific application. How can it be done?

After locking the store, I added an application to "integrated apps" in Microsoft 365 admin center, but nothing happened. I can't select any application (for example in MS WORD) because I get the error message that the store is not available.

Im waited 24 hours and was the same.

I appreciate helping me

Answer 1

 

1. Add Add-in A via Integrated apps.

After several minutes, when I reopened Word and clicked the Refresh button, I can see Add-in A

 

Unfortunately I can't see ****-in in Admin Manager tab. I waited 1 Day and clicked on refresh button

Answer 2

Thank you for the answer. I can't see any apps in the ADMIN MANAGED tab. I'll try your workaround of temporarily turning on the store and deleteing/adding the app.

Best regards

Hi Adbobo,

If you can see the specific add-in now, please ignore this reply. If you still can't see the specific add-in, the following information may help you.

Based on my test, it seems I can reproduce a similar situation. Here are my steps and test results.

1. Add Add-in A via Integrated apps.

After several minutes, when I reopened Word and clicked the Refresh button, I can see Add-in A

2. Turn off the Office Store in "User owned apps and services".

After several hours, Office Store was unavailable in the Office application.

3. After the Office Store was unavailable, add Add-in B via Integrated apps.

So far, I've been waiting for 14 hours, but I still haven't seen Add-in B, but Add-in A still appears and works well on my side.

I have searched a lot, but I didn't find other settings/policies that can control this behavior. Since my results conflict with the above article, and I can reproduce the same situation, I would like to suggest you contact your admin or IT department to raise a support ticket via Microsoft 365 Admin Center> Support> New service request. That support team there has the correct channel to help you investigate more and find what exactly the reason has caused this situation.

In the meanwhile, since Add-in A appears and works well on my side, the following steps may help you.

1. Please temporarily turn on the Office Store in "User owned apps and services". Make sure Office Store is available in the Office application.
2. Please remove the specific add-in from Integrated apps and re-add it again. Make sure when the user clicks the Refresh button, he can see the specific add-in.
3. Please turn off the Office Store.

Hi Adbobo,

Normally, the integrated app should appear in the ADMIN MANAGED tab (the VOM ADMINISTRATOR VERWALTET tab as shown in your screenshot), not the STORE tab. Please click the Refresh button via Get Add-ins> in Office Add-ins, and click the ADMIN MANAGED tab. I would like to confirm if you can see the specific add-in or not.

Also, based on my search, turning off the Office Store does not prevent the admin from using Centralized Deployment to assign an add-in.

For your reference:

Prevent add-in downloads by turning off the Office Store across all clients (Except Outlook)

Deploy an Office Add-in using the admin center

Hi Adbobo,

Thanks for posting in the community. We are happy to help you.

According to your description, you have already added the specific app via Microsoft 365 admin center> Integrated apps, but it didn't appear. If my understanding is correct, we need to do some tests first on our side, we'll appreciate it if you can understand that it will take some time to give you more effective suggestions according to the test result. We will update our reply as soon as possible.

Appreciate your understanding and patience.
