We have issues with Windows XP clients being prompted for network credentials over and over. Never allowing Outlook to open and connect. We have about 200 XP machine left in the environment unfortunately. Since we set up a hybrid CAS server in hopes to eventually start migrating mailboxes to Office 365, this issue started happening. All Windows 7 and greater running Office 2010 or greater aren't affected.
I know the XP and Office 2010 requirements are Office 2010 SP2 and Windows XP SP3. I have verified that they have this patch level.
Troubleshooting Steps taken;
* Installed updates to Windows XP SP3
* Installed updates to Office 2010 SP2
* Setting up a new Outlook profile
* Editing the Authentication settings(NTLM, Basic) and Encryption settings in the current Outlook profile
All our servers are Exchange 2013 CU6 on Windows Server 2012.
I am wondering if we need to run the Set-OutlookProvider command on the Exchange servers... but only article I can find is to do it on Exchange 2007. Wondering if anyone has had a need to and run this on the 2013 Exchange servers?
Set-OutlookProvider -Identity EXPR -CertPrincipalName msstd:*.contoso.com
Could it hurt to run this on Exchange 2013 servers?
Thanks in advance.
