We have an Exchange 2013 CU1 server co-existing with our old Exchange 2007 server. We are only using Outlook 2010. Outlook clients connecting to the old server have no issues, but Outlook clients connecting to the 2013 server are asked for their password every
time Outlook is opened.
Does anyone know how to get rid of the constant password prompts?
Here are some things I have already checked:
- Outlook is not set to prompt for password every time it is opened
- Outlook Anywhere is currently set to NTLM authentication
- I have confirmed that the Exchange virtual directories have the correct authentication settings as per http://technet.microsoft.com/en-us/library/gg247612(v=exchg.150).aspx
- We are using an SSL certificate issued by RapidSSL. This has been installed in the Exchange Control Panel and set in the IIS website bindings.
Many thanks
