The type could not be found or it is not registered as safe

I'm doing an installation on WSS 3.0 (will be moving to 2010 later in the year) I receive this error when trying to add your webpart to a page. "A web part or web form control on this page cannot be displayed or imported. The type could not be found or it is not registered as safe." Do you have any instructions for WSS/MOSS to make sure I'm doing it right?

Hi Rob,

I just change the WSS 3.0 / MOSS 2007 Package, i forgot to include the EWS dll (Exchange Web Service) to the package.

You can deactivate the feature and remove the webpart from the webpart gallery.

Then, go to your central admin and retract the solution and use STSADM -o deletesolution.

Download the last WSS 3.0 / MOSS 2007 package and install the new solution with STSADM -o addsolution.

Deploy, activate the feature and voilà ... :)

Thanks for your feedback.

Damien.

I am getting the same issue with the just downloaded package for Exchange 2013

Exchange WebPart

A Web Part or Web Form Control on this Page cannot be displayed or imported. The type WP_Exchange.WP_Exchange.WP_Exchange, WP_Exchange, Version=1.0.0.0, Culture=neutral, PublicKeyToken=13ea1a424ee211d4 could not be found or it is not registered as safe.

Does this package need the ews.dll as well?
