'Usage
Dim instance As _Store
Dim value As Boolean
value = instance.IsOpen
[DispIdAttribute()]
bool IsOpen { get; }
Property Value
Type: System.Boolean
Remarks
This property supports both Exchange and non-Exchange stores.
IsOpen only indicates if the store is open. It does not indicate if the store is offline, or if it is an Exchange mailbox or an Exchange Public Folder and the store server is down.
Because opening a store can impose a performance overhead, and _Store.GetRootFolder and _Store.GetSearchFolders will open a store if it is not already open, you can use IsOpen before deciding to call GetRootFolder or GetSearchFolders to minimize performance overhead.
