How much space do I have for mail messages? Can I run out of space?

Your account has 25 GB of storage. You'll probably never run out of space. In fact, a heavy email user who sends and receives lots of file attachments and archives all messages might use up to 5% of this space a year (usually less), so it would take decades to use up all of the available space. Also note that Google Apps restricts the size of file attachments to 20 MB, so you don't have to worry about a few large files using up your storage space.

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, click Settings in the upper-right corner of your Mail window, click the Offline tab, and then click Enable Offline Mail for this computer. (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.)

Can I stop messages from being grouped into conversations?

Yes. Click Settings in the upper-right corner of your Gmail window and, on the General tab, scroll down toConversation View.

• If Conversation View is off, new messages won't be grouped into conversations, and any existing conversations are ungrouped into separate messages.
• If Conversation View is on, you can't separate the messages in a conversation. However, if you want to send a reply but don't want it to be added to the conversation, you can simply change the subject line in your reply.

How do I mark a message as "unread" in my Inbox after I open it?

Select the message. Then, in the More drop-down list, select Mark as unread.

Can I recall a message I already sent?

Yes, Gmail Labs has an early version of a new "message undo" feature that lets you recall a message within a few seconds after you send it. To enable the feature, open your Gmail Settings, go to the Labs tab, and enable the Undo Send lab.

Note that your Google Apps administrator must enable Labs for your domain for this feature to be available.

I've heard Gmail search is really powerful. How does it work?

To search for messages, type a word that the messages contain. Note, however, that Search matches "whole words" only—that is, it doesn't recognize partial or similar matches. For example, if you search for benefits, Search won't find benefit or benef. Also, Search doesn't recognize special search characters, such as square brackets, parentheses, currency symbols, the ampersand, the pound sign, and asterisks.

By default, Search doesn't look in your Trash or Spam folders. To search those folders also, click Show search options next to the Search field, and then, in the Search drop-down list, select Mail & Spam & Trash. You can find more information about using Search in the Gmail Help Center.

A list of the advanced search operators is available in the Gmail Help Center. You can also print out this reference sheet.

Can I make Gmail the default email program when I click email links?

Yes, if Google Talk is enabled for your domain. In that case, specify Gmail as your default email program as follows:

1. Open Google Talk.
2. Click Settings in the upper-right corner of your contacts list.
3. In the General dialog box, select Open Gmail when I click on email links.
4. Click OK.

Note, however, that this setting doesn't work for all email links.

Conversations and Messages

Can I reply to or forward just a single message in a conversation?

Yes. Open the conversation and expand the individual message. From the drop-menu at the top-right of the message, click Reply or Forward.

Can I delete a messages from a conversation?

Yes, you can delete one or more messages in a conversation as follows:

1. Open the conversation and expand the message you want to delete.
2. Open the drop-menu at the top-right of the message.
3. Select Delete this message.

Can I open a message in a separate window from my main Mail window?

Yes, if your browser is set to display pop-ups in a new window, you can do the following:

• If you're reading a message, click the New Window icon in the upper-right corner of the message.
• If you're composing a new message, click the New Window icon in the upper-right corner of the message.
