Folder.Bind - "Id is malformed" - Exchange Web Services Managed API

Question

I'm passing the Folder.Id.UniqueId property of a folder retrieved from a FindFolders query via the query string to another page. On this second page I want to use that UniqueId to bind to the folder to list its mail items:

string parentFolderId = Request.QueryString["id"];
...
Folder parentFolder = Folder.Bind(exchangeService, parentFolderId);
// do something with parent folder

When I run this code it throws an exception telling me the Id is malformed. I thought maybe it needs to be wrapped in a FolderId object:

Folder parentFolder = Folder.Bind(exchangeService, new FolderId(parentFolderId));

Same issue.

I've been searching for a while, and have found some suggestions about Base64/UTF8 conversion, but again that did not solve the problem.

Anyone know how to bind to a folder with a given unique id?

Answer 1

I had a similar problem and used urlencode/urldecode to make sure the ids was properly formatted. However one of the users had messages that would result in errors.

It turned out that some of the ids had a + sign in them resulting in a ' ' blank space when decoded. A simple replace of ' ' the '+' did the trick.

Could be the problem.

I know the question was asked a long time ago, but this might be helpful to others in the future.
