So here's my issue. New setup with exchange 2010 in a resource forest. Users are in a separate forest with a trust setup. Most of the users are using windows 7 and this is working fine with outlook 2010. However the windows xp users who are using outlook
2010 are having issues. Every time they attempt to reopen outlook it will ask them for a password. They will then have to type in the domain name/username and password before it will work again. Even checking save password won't work. The only way I've been
able to get this to work is to change network logon security in outlook to NTLM manually and then it will connect them with no problems. Any ideas? suggestions? On how to get this working without having to change the setting?
