[Bug] - MCOIMAPFolderFlag sometimes returns wrong value for trash(deleted folder) with outlook

[caglayansever]

Summary We call MCOIMAPFetchFoldersOperation to fetch all folders. Outlook supports folder flags to identify. Sometimes trash folder flag returns wrong value.

Platform(s)

iOS

Happens on Mail Server

Outlook

Piece of code

            /// Servers which have flag support:
            switch imapFolder.flags {
            ....
            case .trash:
                folder.id = FolderId.trash.raw
            ....
            default:
                /// Folder Flag not supported or custom folder

We can identify Deleted(trash) folder with checking imapFolder.flags == .trash but sometimes Deleted folder returns ▿ MCOIMAPFolderFlag

• rawValue : 257 And this enum is not trash value. The trash rawValue is 256. It returns randomly correct value.
