Reverting To Standard Forms

[Jonathan Wareham]

Hi,

I have an application that uses a custom Task form to display information
looked up from a SQL server. The custom form has been published in the
organisational forms library and I have set each user's Tasks folder
properties to use the custom form 'When posting to this folder, use:', and
it is also in the associated forms list.

Everything works fine other than every now and then the users are finding
the Tasks folder has reverted back to using Outlook's standard Task form.
Can anybody shed any light on this?

Any help appreciated,

Jonathan
