We're in the process of upgrading from Office 2007 to Office 2010. One thing that's been a problem is that the Outlook 2010 folks' OOF seems to be screwed up. When people still on 07 send emails to people that have 10, they get their OOF even though it's off. When people on 10 are sending to others on 10, they don't get a reply. Their status in 10 doesn't come across as being out of office, but when people that are on 07 have their OOF on, the behavior is what you would think should happen. Without giving too much info away the 1st recipient is on 07 and displays correctly (highlighted) and pops up at the top while the 2nd person does nothing.
I checked all the autodiscover settings and everything else. The only differences in policy is that we decided to use cached exchange mode for 2010.
Thanks in advance.
