\"\"This article describes how to get shared folder list from your IMAP server using Mail.dll IMAP component for .NET<\/a>.<\/p>\n

Shared folder names usually start with ‘#’ character. This is not a rule, but it’s very common.<\/p>\n

IMAP server when asked for all folder list should return also shared folders.<\/p>\n

Here’s the unit test code that shows this:<\/p>\n

\r\nList<folderInfo> allFolders = client.GetFolders();\r\nCollectionAssert.Contains(allFolders.Select(x => x.Name), "#Public.PublicFolder1");\r\nCollectionAssert.Contains(allFolders.Select(x => x.Name), "#Public");\r\n<\/pre>\n
If you want to list only shared folders<\/strong> you’ll need to use IMAP’s NAMESPACE <\/strong>command. Imap.GetNamespaces()<\/em> method returns Namespaces<\/em> class which contains information about personal, shared<\/strong> and other users namespaces:<\/p>\n
\r\n\/\/ C# version\r\n\r\nusing (Imap client = new Imap())\r\n{\r\n    client.Connect("server");\r\n    client.Login("user", "password");\r\n\r\n    Namespaces namespaces = client.GetNamespaces();\r\n\r\n    \/\/ List shared folders in all shared namespaces\r\n    foreach (NamespaceInfo space in namespaces.Shared)\r\n    {\r\n        List<folderInfo> sharedFolders = client.GetFolders(space.Name);\r\n        sharedFolders.ForEach(x => Console.WriteLine(x.Name));\r\n    }\r\n\r\n    client.Close();\r\n}\r\n<\/pre>\n
\r\n' VB.NET version\r\n\r\nUsing client As New Imap()\r\n\tclient.Connect("server")\r\n\tclient.Login("user", "password")\r\n\r\n\tDim namespaces As Namespaces = client.GetNamespaces()\r\n\r\n\t' List shared folders in all shared namespaces\r\n\tFor Each space As NamespaceInfo In namespaces.[Shared]\r\n\t\tDim sharedFolders As List(Of FolderInfo) = client.GetFolders(space.Name)\r\n\t\tsharedFolders.ForEach(Function(x) Console.WriteLine(x.Name))\r\n\tNext\r\n\r\n\tclient.Close()\r\nEnd Using\r\n<\/pre>\n
The above code lists all public folders available for the currently logged-in user:
\n
\n#Public.PublicFolder1
\n#Public.PublicFolder2
\n#Public
\n<\/code><\/p>\n
Please note that server will not let you select<\/strong> some folders. In the example above the user can not select ‘#Public’ folder. You can use FolderInfo.CanSelect<\/em> property to check if the user is allowed to select the folder.<\/p>\n
