If your ISP or web hosting provider allows you to set up your own e-mail addresses, consider setting up a separate address for each web site you register on. This is easiest if you have your own domain name and you can set up generic forwarding for all addresses under the domain.

The advantage is that this approach allows you to easily verify e-mail senders. For example, if you change your e-mail address on PayPal to "john.doe.paypal@ExampleOnly.com" and the "To" address of a received message has something different, it's probably spam for a phishing scam that didn't come from PayPal.

Clicking Outlook "To" Header Does Not Display HTTP "To" Header

Some unsubscribe links don't automatically fill in the e-mail address, and if you don't enter the right recipient e-mail address it won't work. You can't just click on the "To" address to see what address the unwanted mail was sent to because Outlook the address(es) from the address book (for example, FirstName.LastName@ExampleOnly.com, NickName.LastName@ExampleOnly.com). If this wasn't the address the message was sent to, unsubscribing it won't work.

To determine the actual address the spam was sent to, do View -> Options... on the message and look at the actual HTTP headers. If the message was sent to a single user, the actual e-mail address should be in the "To" header.

By default, messages are stored on the Exchange server. The amount of space for these messages may be restricted by size limits set by the administrator.

Creating a .pst file on the local hard disk may change the frequency that e-mail messages are backed up, since the .pst file stored on the local hard disk will be backed up with the other files on that system, rather than the ones on the server. In addition, you can backup the e-mail messages separately.

To avoid any issues with space on the server, e-mail messages can be stored on the local hard disk. Select Outlook Data File... from the New toolbar button or menu option. In the dialog, the following options are recommended:

1. Select Office Outlook Personal Folders File (.pst). The option with Office Outlook Personal Folders File (.pst) is the format for earlier versions of Outlook.
2. Under Encryption Setting select Compressible Encryption to provide password protection and enter a password under Password.

To back up e-mail messages in Microsoft Outlook, select Import and Export from the File menu. In the import/export dialog, the following options are recommended:

1. Select Export to a file.
2. Select Personal Folder File (.pst).
3. Select the folder to be backed up. Select the Include subfolders check box.
4. Under Save exported file as use Browse to find the directory where the backup is to be created. If you select an existing backup file, the exported messages will be added to it. Or use a new file name so that the backup will contain the same messages as the original file.
5. Select Replace duplicates with items exported.
