Turning off PowerTalk
To turn off collaboration services for an extended period, click the Off button
in the PowerTalk Setup control panel and restart your computer.
When you choose this option, collaboration services won’t be available at all
when you restart the computer. (Your Mailbox and Catalogs will not appear
on the desktop.) You’ll use this option when you know that you won’t be
needing PowerTalk services and accounts on a particular personal computer
for a while. You may also use it to save memory, since PowerTalk uses no
memory when it is turned off.
To turn PowerTalk back on, open the PowerTalk Setup control panel, and
click the On button. Then restart your computer.
