I have all the PCs in the network with outlook auto archive configured and for several days it hasn't worked well for many of them, including mine with Outlook 365. In my case it archives all folders well except the 'inbox', I changed from 4 months in 16 weeks and it archived correctly. I have a similar problem on a client with Outlllok 2010 but even if I change months to weeks or days it doesn't archive my mail anymore. I tried to create a new archive file too but nothing happens .. This is a big deal.
