public FolderId FindFolderIdByFullName(
	string folderFullName,
	int recursionLevel
)

Public Function FindFolderIdByFullName ( 
	folderFullName As String,
	recursionLevel As Integer
) As FolderId

Parameters

folderFullName

Type: SystemString
The full folder name, such as "Inbox/Nested folder/Deeply nested folder". Null reference (Nothing in Visual Basic) or empty string not allowed.

recursionLevel

Type: SystemInt32
Specifies how many levels of folder hierarchy to scan in shallow mode before switching to deep traversal mode. If 0, the entire account will be searched in a single operation (deep traversal). Higher values increase the number of search queries to the server but make each query more lightweight. Negative values not allowed.

Return Value

Key difference of this method from DownloadFolderByFullName(String, Int32) is that it returns just ID. This means that MailBee requests less info from the server making this method a bit more efficient. However, if you need the detailed info about the folder (e.g. message count, unseen count, etc), use DownloadFolderByFullName(String, Int32) instead.

Note
This overload exists only for optimization purposes when dealing with very complex and deeply nested folder hierarchies in Exchange accounts. DownloadFolderByFullName(String, Int32) topic provides more details on recursionLevel and how it can help improve performance.

Note
This method is not implemented in .NET Core. Use FindFolderIdByFullNameAsync(String, Int32) instead.
