Hi, I would like to know what is the maximum allowed size for a task/form?

Some of our users are experiencing loss of information when a task reaches a
certain size (~ 20MB +). Some peviously inserted emails become corrupted and
cannot be opened anymore. The error message they are getting is "One or more
parameters are incorrect."

Thanks

A form is just a UI/code template. I can't imagine a single form being 20MB.

Maybe you're talking about an item reaching that size? There definitely is a size limit of 32kb for all data other than the item body and any attachments. Once you reach that, the item may start exhibiting all kinds of odd behaviors.

You can look up the error message you're getting in the Microsoft Knowledge Base at http://support.microsoft.com

Thanks Sue.

Yes, I am referring to the size an item, not the form itself.

We usually insert many emails inside a task (Insert > Element) and sometimes
it can get pretty big (20+ MB). At some unknown size, elements inside the
task can become corrupted and cannot be opened anymore. It's easy to spot
them as the Message icon inside de task is replaced by the generic Windows
document icon. I'm looking for the SIZE over which an item begins corrupting
elements inside it. I searched everywhere in MSDN and couldn't find the
answer.

Yours would seem to be is a very rare scenario. There is no documentation that speaks to it. You might want to file a support incident with Microsoft. They may never have seen this one before.
