I have a infopath form which is linked to sharepoint list. We have setup groups and setup the permission for the groups. This has been working okay for a year no problem. We have both internal and external (via extranet) access the sharepoint site then view the infopath form. For the past 3 weeks when any new user is added to the group then can access the sharepoint site but when they click the infopath form to view it says access denied.
Any assistance will be appreciated.
