Same webmail ability can be at user end also. required the particular user’s logon credentials. there you can the out of office and also you can create a new outlook profile for the manager in Secretary’s outlook , so she can set out of office enable
I would create a new Outlook profile on the same computer as the secretary pointing directly to the manager’s mailbox. Then once connected, you will be able to create your Out of Office.
To be more specific, have the secretary close outlook then go to the control panel and click the mail icon (switch to classic view if necessary). Then click show profiles. From there select the radio button that says “prompt for a profile to be used.” and click OK. Open outlook and you will get a prompt window. Click the “new” button and add the manager’s mailbox in as a profile. When the secretary opens the manager’s mailbox in its own profile this way he/she can go in and enable the out of office for the manager.
