We use WebDAV to share Outlook calendars.
I set up a WebDAV server with IIS on Windows 2012 R2. It works fine.
This Windows 2012 R2 is on the local network and it belongs to an Active Directory's domain. Every client are also on the local network, and belong to the same domain.
The WebDAV's IIS site only use "Windows authentication", which is the recommended setting.
When a domain user access a WebDAV share for the first time, he has to wait about 5 seconds before he is required to enter credentials. The user then type his domain user/password and the access is granted.
The WebDAV credentials are stored into the Windows's credentials cache (you can see/modify then with
If the user then change his domain password, the access to the WebDAV share no longer works, because the credentials used are the old ones stored into the cache.
This behavior is seen when using WebDAV from Outlook and from explorer.
We currently need only to solve the problem for Outlook.
Question: How to make Outlook use the currently logged user credentials, instead of asking to type it? So when the user change his password, everything still work.
Update: On a client computer I explicitly put the WebDAV share into the intranet zone of Internet Explorer. I also explicitly configured Internet Explorer to use the current user's credentials (this is not the default setting). But no improvement.
