IsSelectable is false

Question

I have some folders with "*" in the name, for example "** RCC **".

When i get folders list, the property IsSelectable is false, how can i see the emails in this folder?

Answer 1

The IsSelectable property is false for IMAP folders with '\noselect' IMAP folder attribute. This attribute indicates that the folder is not selectable. This implies that:

1. This folder is not supposed to contain any emails. (It is most likely just a node in a hierarchy of IMAP folders.)
2. It is not possible to list emails in this folder. (However, there are not supposed to be any emails there anyway.)

Comments

Any folder that contain "*" show my as IsSelectable false.
This is a commun folder, has many emails inside.

IsSelectable is false for folders that are listed by the IMAP server with "\NoSelect" attribute. Whether or not the folder name contains "*" is irrelevant from Rebex IMAP's (or other IMAP client's) point of view. If any folder that contains "*" shows with IsSelectable false, that implies that the server lists those folders with "\NoSelect" attribute. And, as your log confirms (EXAMINE command is just a read-only form of SELECT command), it is actually enforcing this non-selectability.

If these folders actually do contain emails, and are not supposed to be non-selectable, this would be a server-side issue. There is nothing an IMAP client can do about it, unfortunately. It's the IMAP server that's listing those folders as non-selectable and refusing to select them.

i change the folder name replacing "**" to "." and work, i'll analise the server-side.
thx so much.
