How long until I'm up to speed with Google Apps?
You should be able to begin sending and receiving mail, scheduling calendar events, and managing contacts right away, without any trouble. Becoming accustomed to Gmail's unique mail management features such a conversations and labels can take a bit longer. Within a week, however, many people find that they not only become comfortable with Google Apps but also appreciate the benefits so much that they no longer miss their old application.
Can I open my email or calendar in new tab (not a new window)?
If you use the Chrome browser, links will open in new tabs by default. If you're using another browser, you can change the browser settings to open new tabs instead of new windows.
Can I access my mail offline?
Yes, you can set up Gmail for offline access to your most recent email messages. To enable this feature:
From any Gmail page, click the gear icon in the upper-right corner of the mail window.
Click Settings, open the Offline tab, and click Install Gmail Offline.
Note, however, that if your Google Apps administrator has disabled offline access for your domain, the Offline tab won't be available, and you won't be able to use this feature.
Do I need to use my company's VPN to access Google Apps when I'm offsite?
Not typically. In most cases, you can just go to admin.google.com in any browser to access your email and calendar, from any location. However, some companies might require VPN access to Google Apps. In that case, if you're outside your network, you must first connect to the VPN before you can access Google Apps.
