‘exchange server administrator has blocked the version of outlook
Our server has Microsoft Exchange 2010 installed with Microsoft Outlook 2007/2010. We have a new client that uses Microsoft Outlook 2003 and have loaded Microsoft Outlook 2003 on a few machines but are having a problem connecting them to our Microsoft Exchange 2010 server.
We encountered an issue with encryption but were able to solve it by selecting the outlook client and clicking the encryption checkbox. A new problem has now arisen that we are unable solve. Presently we are receiving an error message stating 'exchange server administrator has blocked the version of outlook'.
For Outlook 2003 to successfully connect to the 2010 Exchange server, do we have to enable the public folders on the 2010 server?
