When I am trying to join a group using Outlook Add-In I can't see any groups under the join menu. The group exist in the fim portal and I can access to it from the portal. The portal is also able to send for example notification emails.
The picture shows a part from a joining message generated by Outlook. When I press the join button shown in the picture, I can't find any groups from there.
Ok, I can't add any pictures because my account is not verified.
