This article and guide will teach you how to share your Google Apps email inbox with another user.
Many business people have a PA, manager, or co-worker that they need to share email access with. The Google Apps email sharing function allows other people in your organisation to view and reply to emails on your behalf.
How?
In Google Apps it is relatively simple to enable email sharing and access for other users within your domain.
Login to your Google Apps email at mail.google.com/a/yourdomain.com
Click on 'Settings' in the menu at the top right of the page.
Click on the tab 'Accounts'.
Under the option 'Grant access to your account.' click on 'Add another account'. You will then be asked to enter the email address of the person you wish to give access to your emails; make sure you don't enter an email alias here. Click 'Next Step', and then 'Send email to grant access.'.
Login to your Google Apps email at mail.google.com/a/yourdomain.com
In the menu at the top right of the page you'll see your email address. It should be highlighted in blue and have a little blue arrow pointing downwards. Click on your email address and a menu will appear allowing you to access other email in-boxes that have been shared with you.
Please note that you can only access shared emails using the online Gmail interface and not Google Apps sync for MS Outlook.
You're done :)
