How to update custom app completely on all outlook clients?

Hüsing, Georg 0 Reputation points


I removed integrated office (outlook) app in Microsoft 365 admin center and added a new version of this app, but only the old addin version is offered on most outlook clients.

After 12 or more hours, only a few outlook users got the new addin, currently the tenant admins. I checked it in Outlook on the Web.

Is this because of the same ProductId of the old and new addin version? How can I enforce app update in outlook? Will the app removal or deployment faster if I use a user scope? Is the deployment of a test app slower or faster?

Best regards, George
