Question:

>> Our company uses GMail for corporate mail. How can we configure the SharePoint to work with @gmail mailbox?

Answer:

I got several questions how to configure the SharePoint on Windows Server 2008 to alternative email addresses when you don't have Exchange (for those who don't know Microsoft removed internal Mailbox support from Windows Server 2008).

There are several solution for this situation - using 3rd party mail servers, like Visendo and others. But in some cases you company can use GMail or Live mail for the corporate correspondence, and you need to configure your SharePoint to work with external mail servers.

Such configuration a bit tricky but possible. I recommend to read that post http://www.oceanapproach.com.au/blog/Lists/Posts/Post.aspx?ID=44 where described how to configure SharePoint to work with GMail accounts

It is important to realize that SharePoint stores a complete binary copy of every version of your document in the SQL Server database.

If the "Require Check Out" option is not enabled and a user forgets to check out the document first, a new version will be created every time a user saves the document to the server. This can lead to hundreds of versions of a document over time. But, if the document is checked out before it is edited, all changes will be saved to the same checked-out version

For example, you have a document that is 250 KB in size and you create three past versions of it along with the current version, a total of 1000 KB will be stored in the database along with appropriate metadata for each version. This formula applies equally to both major and minor versions.

PS: "Required Check Out" option is found on the Versioning Settings page of the Document Library Settings.
