Kerio version 7.4.2 build 7813
We have multiple users imported from the Open Directory, all of them work fine except for one user who was moved from a external group on the server to a internal group, since the person was hired by the company fulltime.
Ever since, after changing the group ID in the workgroup manager, the user can only sent invitations to attendees from her own computer in iCal, Mac OS 10.7.5
We don't have delegations setup, instead we add every user account to iCal so we don't bump in to delegation issues with read/write, etc. I know its not the most practical way but it works. Whenever I make an appointment on the persons computer in iCal, I can add invitees. On another computer, not. This is very strange and we tried most suggestions found online, yet they don't work.
I thought it might be a permissions problem so I removed the user in Kerio, re-added it and tried again, same error. Also removed the user completely from Kerio, and the workgroup manager / server. After adding the user again with the right user ID's and groups the problem still persists.
I am not sure how to troubleshoot this anymore, nor can I find any "advanced" calendar settings in the Kerio administration web interface. I hope somebody has another suggestion or a clue what I could try to do next.
This issue occurs on all Apple computers except the users own, however all the account are configured exactly the same in iCal, except for on her own computer she logs in with her own credentials in the finder.
Any help is greatly appreciated, many thanks!
