we have one mailbox shared to our users to read within the web client. This worked fine until the update to 6.0.1 (from 5.x) yesterday.
Now if the folder of the shared account has the same name as a folder in the peronal mailbox (i.e Inbox, Sent, ...) the contents of the personal folder is shown, not of the shared mailbox (search line reflects that the personal inbox is selected). If I try to manipulate the search box entry to include the shared accounts name it switches back to the old entry.
If the folders name is different it all works fine.
