!)when using RPC/HTTPS connection in Outlook, you will need to follow the instructions below to store your password so Outlook will not prompt you for credentials. You must be running on Windows XP or Vista (any edition except Windows Home).
2) In Outlook 2003, go to: Tools > Email Accounts > Click Next to View or change existing email accounts > Highlight Microsoft Exchange Server and click Change.
In Outlook 2007, go to Tools > Account Settings > doubleclick Microsoft Exchange.
Click More Settings > Connections tab > Exchange Proxy Settings.
Select NLTM Authentication as the Proxy Authentication Setting
In Windows, click the Start Menu > Run > Type in “control keymgr.dll’”
You’ll see Credential Manager window with an entry with the Exchange Server name.

If you are missing the Add button you may want to modify Windows Registry to save the password. Note, that for editing Windows Registry administrator rights are required, because it is not safe and you will perform it on your own risk.
In Windows, click the Start Menu > Run > Type in “regedit”
Navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\
Find DisableDomainCreds entry. Value of 1 (enabled) will prevent you from saving new credentials.
Change the value to 0 and reboot. You should have the Add button. Note, that the value of 0 is the default value.
Also check LmCompatibilityLevel entry. It should be set to 3, which is a default value. If you have another value, change it to 3. If it does not work with 3 then also try it with 2.
Reboot the computer to apply changes.
