John, Geoff I have made some progress diagnosing something changed with createIncomingServer presumably with 60.*  The extension I took over LocalFolders creates additional local folders using the type "none".  The basic code for this is below which has been working for many years.  60.* to the normal thing of creating both special folder Trash and Outgoing Mail.  Besides the expected .msf files, now actual local file system folders are also created. These are not .sbd folders, just the straight names and both are empty. At this point it is not possible to place any messages into the trash folder. If I delete the empty folders (either within Thunderbird or externally) then reboot , it becomes possible to place messages into Trash or any newly created subfolders within the server root. I have traced through the code and cannot identify where the empty folders are created. I presume there is something like an update function to update folder status, something not necessary before. So I think my questions are: What methods are required to create a valid "LocalFolder" with appropriate status. What is required to update the folder structure without a reboot. Thanks to all for help so far Christopher eu.philoux.localfolder.creeDossierLocal = function (nom, chemin) {     try {         var accountmanager = Components.classes["@mozilla.org/messenger/account-manager;1"].getService(Components.interfaces.nsIMsgAccountManager);         var srv = accountmanager.createIncomingServer("nobody", nom, "none");         var filespec = Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsIFile);         filespec.initWithPath(chemin);         srv.prettyName = nom;         srv.localPath = filespec;         // console.debug('before create account');         eu.philoux.localfolder.LocalFolderTrace("before create account");         var account = accountmanager.createAccount();         account.incomingServer = srv;         return account;     }     catch (ex) { eu.philoux.localfolder.LocalFolderAfficheMsgId2("ErreurCreationDossier", ex);         return false;     }     return false; }

You may want to review whether that code does the same as https://searchfox.org/comm-central/source/mailnews/base/src/nsMsgAccountManager.cpp#2100, which creates the built-in Local Folders account (apart of setting the account as the main Local folders account in the pref). >  Besides the expected .msf files, now actual local file system > folders are also created. > These are not .sbd folders, just the straight names and both are empty. Are those actual folders, not just files? The Inbox folder should be represented by the file Inbox and it's Inbox.msf. There should be no Inbox or Inbox.sbd folder until you create a subfolder inside the Inbox via Thunderbird. We have touched the .sbd suffix handling e.g. at https://hg.mozilla.org/comm-central/rev/d7d59e4c13d72e96641c5bcebe5e18bb8d4f46eb , you may try to check it for errors. The intent of those patches wasn't to change the behaviour in any way. > At this point > it is not possible to place any messages into the trash folder.

It seems those default folders are created here: https://searchfox.org/comm-central/source/mailnews/local/src/nsNoIncomingServer.cpp#127 You can try to trace what it does there. > I have traced through the code and cannot identify where the empty > folders are created. > I presume there is something like an update function to update folder > status, > something not necessary before. > So I think my questions are: > What methods are required to create a valid "LocalFolder" with > appropriate status. > What is required to update the folder structure without a reboot. > > > Thanks to all for help so far > Christopher > > > eu.philoux.localfolder.creeDossierLocal = function (nom, chemin) { > >     try { >         var accountmanager = > Components.classes["@mozilla.org/messenger/account-manager;1"].getService(Components.interfaces.nsIMsgAccountManager); > >         var srv = accountmanager.createIncomingServer("nobody", nom, > "none"); >         var filespec = > Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsIFile); > >         filespec.initWithPath(chemin); >         srv.prettyName = nom; >         srv.localPath = filespec; > >         // console.debug('before create account'); >         eu.philoux.localfolder.LocalFolderTrace("before create account"); >         var account = accountmanager.createAccount(); >         account.incomingServer = srv; > >         return account; >     } >     catch (ex) { > eu.philoux.localfolder.LocalFolderAfficheMsgId2("ErreurCreationDossier", > ex); >         return false; >     } > >     return false; > } > >
