Hi Is it possible to use some managment tool in corporate network of Thunderbird Clients? We have clients in our company deployed with one version when reinstalling workstations. As Thunderbird can be set so that it does not download the update, it is still in a state where at least it asks and the user clicks on it. The question is that is it possible to do this in some software or update center??? The point ist we dont have the control over the clients updates. We wont to release these updates for the whole company when we agree not when the users do so by accident. What often happens to us, the versions are then different and we would like to have it under control. Imagine we replace 100 workstations a year. The version is the same. Time will pass and in 3 months it will be a mess. Is there any way to keep it in order ??? Tips on how to keep one version in a large network and then do a massive update on 100+ workstations. This mess of various versions then causes a problem for users with different views and unnecessary problems in managing clients for administrators in our company. When we know that version 80 is good and then that 85 is good again or does not cause any problem in our environment after the tests. Then we will deploy it for everyone. Thank you for your help Lubomir
