we have several clients running outlook 2007 configured with cached mode and RPC/OVER HTTP . The Exchange server is 2010 and it's on a cloud service provider.
In the last few months we decided to get rid of PSTs moving all the messages into the mailboxes . We did this operation using the copy of folder within outlook.
NOW the problem
The result is that the ost on each client is almost 10GB but the mailbox size on the cloud provider is much much less and , this is the tragedy, all the messages are stored on the ost but only few were sync on on the exchange server ( we discovered this making a comparison with owa).
Something went wrong with the sync between ost and the cloud exchange i guess?
Now we are in a situation that if one of the cdesktop/laptops broke we don't have any backup of messages. How can I syncronyze the messages in the ost with the exchange server? and is there I can be sure that the sync process went fine.
