Outlook Doing Full Sync after Emails are Vaulted
We have EV 10.0.3 with users running Outlook 2010-addin with Light functionality.
Settings are set to use Vault Cache and sync only items that are opened.
Users use Cached Exchange mode for Outlook Profiles.
Provisioned a whole bunch of users at one of my sites late yesteday and today noticed those users Outlooks are doing a huge sync and killing the network.
Checked if it is Virtual Vault sync but it isnt as users have 0 items it thier cache. Tested by opening an item and then approx 37Kb synced to the VC.
So assuming this is Outlook syncing its OST after seeing the changes in the Mailbox on Exchange?.
Confirmed it must be this as all the traffic is coming form the CAS server.
So is this by design? Does Outlook re-sync its OST?
Checked the changes of an OST on a user and it hasnt grown or reduced so again assuming its simple syncing the folder structure and updating.
Is this by design and can anyone confirm this is normal behaviour?
