I'm not sure if this is the correct board to ask this on but it looks like the best match. I'm having a problem with an MDaemon mail server and trying to upgrade Outlook.
Currently they are using Outlook 2003 and are wanting to upgrade to Outlook 2013. I've upgraded a couple of the machines already and all seemed to have went well except now on the ones that have been upgraded they are no longer able to use the shared calendar or contacts. Also, one of the Outlook 2013 is also not able to use the search feature to search through emails. Does anyone have any idea what might be causing this problem?
