Outlook: unable to search in subfolders of shared mailboxes

A few days ago, we took our last users off Outlook 2013 client and placed them on Outlook 2016.

After this, they were no longer able to search in the subfolders of multiple shared mailboxes.

Is there a way to search to more than one mailbox their subfolders? Ctrl+Shift+F doesn't allow more than one data file.

If needed, I can use automapping or map them myself. Most important is that the search option is working properly again.

Any suggestions or ideas?

I think this is by design that we can only search current folder for shared folders. To include the shared mailbox in the scope, you need to manually reselect Current Folder.
