We recently upgraded all of our users Groupwise Clients to release 8.0.2 HP2 and before the upgrade a user could attach pdf documents from Adobe Acrobat Reader by going to file -> attach to email. Also they used to be able to attach word and excel documents through office in a similar way. Since the upgrade users can no longer do this. Now when they go to "attach to email" it just prompts them with "An error occurred while sending mail". I have looked around and haven't found a fix so thought I would try here. Is anyone else having this issue or is there a setting/fix to enable attaching emails through other programs like office and adobe.

Any help would be great,
