If you had proxy access to an email account prior to the switch to Gmail you should still be able to access those accounts via Gmail. Gmail uses the terms delegation or sharing rather than proxy. To access this account:
- When in Gmail, find your name in the upper right corner. There should be a down arrow after your name.
- Click on that down arrow, you should see the shared
accounts listed. If you do not, click on the Switch Accounts link, then
click on the account you wish to view.
- When you click on the account it will either open in a new tab or a
new window depending on your browser settings.
Note: Your personal email will
remain logged in and you should be able to keep both accounts open at
the same time and switch between them.
