We're currently using Outlook 2013 (online mode) but about 20 of the 50 users are using multiple mailboxes.
So a user has full, send as, send as behalf permissions on the delegated mailboxes.
I have tried to add a register key called DelegateSentItemsstyle : dword 000001
\\HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Preferences\DelegateSentItemsStyle (1), but this solution doesn't work because outlook is in Online mode and if I switch it to cache mode then it works but the amount of storage for the ost's is sizing up pretty quick.
The other solution is to add multiple exchange accounts in outlook 2013 but the searching is not optimum.
Can you provide me with a solution to handle this problem, unfortanely exchange 2013 hasn't got the exchange 2010 rollup 4 for changing a setting for the delegate send items on a specific mailbox through powershell
We have a terminal server environment (Windows server 2012 R2).
