We're running on exch2010 with outlook 2010 in cached mode
The outlook social connector sync seems to pull down most fields, but not otherTelephone / Business2
If i open the Address book "global address list", find the employee and check the "telephone" tab - then the field is filled.
If i create a new contact with that users email address in my local contacts and click on "sync" it is fully updated with photo, contact information etc - but the othertelephone/business2 field does not make it across?
