You’ve created several signatures that you use for various types of emails. Then, you get a new machine and have to set up Windows and all your programs again. However, you can easily preserve your signatures in Outlook and restore them to the new machine.

Signatures are not stored in the .pst file Outlook uses for email messages. They are stored in the following location:

C:\Users\%username%\AppData\Roaming\Microsoft\Signatures

01_signatures_folder

There is an easy way to open this location from within Outlook. Click the File tab.

02_clicking_file_tab

On the Account Information screen, click Options in the list of menu items on the left.

03_clicking_options

Click Mail in the list of menu items on the left side of the Outlook Options dialog box.

04_clicking_mail

In the Compose messages section, press Ctrl while clicking on the Signatures button.

05_ctrl_click_signatures

The Signatures folder opens in Windows Explorer. To backup your signatures, simply copy all the files in this folder to another location.

06_signatures_folder_open_from_outlook

To restore your signatures, copy them from your backup location back into the C:\Users\%username%\AppData\Roaming\Microsoft\Signatures location. The next time you open Outlook, your saved signatures will be available. If you had signatures selected as default signatures for new emails and for replies and forwards, you’ll have to define those again.

NOTE: Each signature you create in Outlook exists in three formats: Plain Text (.txt), HTML (.htm), and Rich Text (.rtf). You need to backup all these formats for each signature.
