Today I received a call from a customer where the inbox did not display any content at some users – but only in the Notes client, not in iNotes !!

After some investigations I remembered, that I had this issue some months ago and found the following IBM technote:

So if you create a folder with and the first character of the folder is a space, this folder is displayed instead of the inbox and it seems, that the inbox is empty.
