Question

I have a basic C# form where the user select a folder from outlook (using Microsoft.Office.Interop.Outlook.Application.Session.PickFolder())

I want this folder to be saved so every time the user opens the form, the last select folder will be restored.

How can that be achieved?

Thanks

When the user picks the folder via PickFolder(), store the Folder.EntryID and Folder.StoreID of the selected folder. You can then use Session.GetFolderFromID() to retrieve the previously selected folder.

See this MSDN example for reference.

Outlook.Folder folder = Application.Session.PickFolder() as Outlook.Folder;
Outlook.Folder folderFromID = Application.Session.GetFolderFromID(folder.EntryID, folder.StoreID) as Outlook.Folder;
