Outlook 2010 Beta integration with Communicator 2007 R2

Asked By 0 points N/A Posted on -

I installed Microsoft Office 2010 Beta, and then I found that it does not integrate well with Communicator 2007 R2 and the Live Meeting Add-in does not work either. The error message says,

” Your Exchange server is temporarily unavailable. Communicator will automatically continue trying to reconnect. If this problem continues, contact your system administrator.”

Generally this means that the client is unable to find the OCS server. There are 2 things that you can try:

1) If your client is set with "automatically sign in" please make sure you have all the correct DNS entries with your DNS server

2) If your client is set with "manual config" please make sure that you have put the servername and correct port, e.g. ocspool.company.com:443

Hope this helps!
