Dsstore not updating Phonechatforfree

I disable cache mode and it works fine but I don't want to keep it disabled, I also tried by delete the OAB file in C:\Users\username\App Data\Local\Microsoft\Outlook\Offline Address Books and download OAB manually rather then waiting for 24 hours, it's still same.

I might have a problem with my Offline Address Book in Outlook.

For me, new colleagues are not showing up and the contact pictures aren’t displaying either.

in the TCP/IP settings of the network interface: As much as it may appear strange, this is the only solution to ensure Windows will register both the A and the PTR records for a DHCP network connection; otherwise, it will only register the A record. sends option 81 and its fully qualified domain name to the DHCP server and requests the DHCP server to register a pointer resource record (PTR RR) on its behalf.

The dynamic update client registers an address resource record (A RR). the DHCP server can be configured to instruct the client to allow the server to register both records with the DNS.

It does work when I call it from the Share Point site, but If I call it from a WCF service (built on top of Share Point's WCF factory) it does not updates the field (and it does not throws an exception or anything) Any ideas?

[UPDATE] Here's some sample code so you can see what I'm doing, lets start with the service implementation: [Basic Http Binding Service Metadata Exchange Endpoint Attribute] [Asp Net Compatibility Requirements(Requirements Mode = Asp Net Compatibility Requirements Mode. First Or Default(); to get the group and then the taxonomy value which it does fetch.I've stumbled upon a strange behaviour with Windows machines, which seems to be fairly consistent between all Windows versions from Vista/2008 to 8.1/2012 R2; it doesn't happen instead when using Windows XP or Windows Server 2003.The problem is this: when the network adapter is configured for DHCP and the DHCP server doesn't register DNS records on behalf of its clients (because it can't, or because it's not configured to do so), then A friend not on SF said: "That's normal, PTR is only updated by DHCP in Win2K ".If the update mechanism appears to be broken for you, it could be because of a corruption in your OAB or in your mail profile.In that case, you can completely reset it by deleting the files making up the OAB or by recreating your mail profile.I also have had this problem with a very large spreadsheet that just stopped updating itself over the weekend, but having checked the above solutions, setting were already set to automatic, and sheet is too big to rebuild, so I was at a loss.
