We are deploying Office 365 to about 2800 workstations. We are blocking the OneDrive personal and forcing employees to use OneDrive Business accounts by applying the GPO: "Block Signing to Office = Enable - ORG ID only." It works fine HOWEVER I am noticing some workstations are unable to access the Apps for Office Store to download apps such as dictionary and translator...When going to Word or Excel>Insert tab>the click on Store and get this error "Please add or enable app catalogs from the Trust Center." If they go to File>Options>Trust Center>Trust Center Settings>Trusted App Catalogs>the box "don't allow apps from the Office Store to start" is checked. If they uncheck and click ok, the box REMAINS checked. Some workstations aren't experiencing this issue thus can access the Office Store with no issue. I have reviewed my user configuration GPO for Office 2013 and cant figure out how to resolve this issue. I want to block the personal OneDrive but still allow users to access the Apps for Office Store. Thanks

Hi,

I've been researching on this issue for a while, so the checkbox "Don't allow apps from the Office Store to start" is unticked for these users who are not affected, correct?

In your scenario, the option doesn't seem like being disabled by the policy; if it is, it should look like below:

So I'm wondering if this is just not related to the GPO or registry.

Try to disable all add-ins in Word, check if the issue persists.

To disable add-ins, click FILE -> Options -> Add-Ins.

Thanks Melon,

I have disabled all add-ins in Word, but the apps store is still giving the same error "Please add or enable app catalogs from the Trust Center"

I am able to uncheck the box now to not start office apps after repairing online Office 365 Pro Plus and then I can get to the Office store and download apps.
