Hello Claudio, > Yeah, the problem in using a logon script is that it should be timed to run > exactely after Thunderbird upgrade and before the new Lightning install. > > I don't think it's possible. that's a problem, indeed. If I remember well, some time ago people on this list used two wpkg systems - one for WPKG client as system service, and one for the logon script - to get things done. > > Btw, i am forced to use the %userprofile% variable since ufortunately the > default location of that DAMNED calendar (i have yeto to understand why it > cannot be integrated directly in Thunderbird from the start) is > %userprofile%\appdata\roaming\thunderbird\Profiles\random.profilefolder\extensions. > And i cannot simply delete the thunderbird folder because the users would > lose all the old calendar entries, mail settings and message filters. So the easiest script would do the following (schematically): loop thru all %userprofile%..\* folders as %i if exist %i\appdata\roaming\thunderbird\profiles.ini get name of real folder from profiles.ini as %j delete %i\appdata\roaming\thunderbird\%j\extensions\{42b649d0-62e0-11da-8cd6-0800200c9a66} end if endloop Instead of "get name of real folder from profiles.ini ..." you could loop thru all folders within thunderbird\Profiles\, this should do pretty much the same as there is usually only one profile folder in.
