I've customized some form that work on public folders as task, named
"Commesse".
Recently, afterby creating a new task and saved it in the public folder,
when I try to open the new task created compare the message:
"Impossible opening the customed form. It will be used a outlook form;
Operation not done" (my traslation from italian)
And then, a new message:
"It's impossible to open form"
Note that the task is visible but is not possible have access to it.
Thank
