Offline Address Book issues

We seem to have had this for qute some time now.

Whenever manually sending/receiving in outlook we get an error which is seeming to be related to the OAB not syncing.
ALso some machines are not updating contacts in outlook that are on exchange.

Error in outlook is unknown error 0x80072f06

Deleting local OAB resolves the new exchange contacts and update on outlook clients.

However the error still persists and when clicking on the - send receive groups - download address book option (in outlook) i only see: download offline address book list, whereas in the past we would see: a drop down box including half a dozen address books.

Exchange 2010 sp1 still...  But dont want to SP3 it until i know the problem is.
Could also have happened after we deployed Active Sync and OWA using SSL certs...

Ideas?

Error 0x80072F06 means there is a problem with the common name on your cert
Ensure the common name is resolvable internally to your CAS server's IP addres

I had same problem and was related proxy. Ensure your local computers are configured to not use proxy on local LAN, because OAB on Exchange 2010 is web deployed.

This post may help you if not proxy related: http://www.msexchange.org/articles-tutorials/exchange-server-2010/management-administration/offline-address-book-part1.html

Yes, Outlook uses IE proxy config.

well odd then, as i have 2x machines logged on as myself with no proxy on each and both are erroring.
but one is showing the 6x address lists and the other is only showing the download offline address book list

Could you check if your server is generating OAB and is accessible?: http://blogs.technet.com/b/rmilne/archive/2012/08/10/outlook-fails-to-download-oab.aspx

should my local paths be the mail.domain.co.uk paths?
e.g. internal: servername.domain.local/activesync - be: mail.domain.co.uk/activesync

as per above they can now open the root folder but not the OAB one i.e. 45455b4hb34j-r4234b55b34j-  etc...

Can i delete and recreate it on the server by updating OAB?

tried removing public folder distribution, no joy.

manually added permissions on the 45455b4hb34j-r4234b55b34j- folder also.

okay, changing the local OAB url to the ssl cert url i.e. mail. has fixed it.

question is why was the local one not working and is there a problem with using mail. as the local url?

CHI-LTDAuthor Commented:
strange why the local cert that we have installed on our clients and is configured on exchange local path for OAB fails.
Using the mail.domain.co.uk/oab url in the local path fixed it..

However now users default address list is not the GAL but one of the other address lists..
