Open Entourage > Preferences and select the Calendar option as shown below:
The option to note here is related to the deletion of old calendar events. Setting Entourage to Delete non-recurring events older than "X" days/weeks/months is generally a good idea as calendar items add to the amount of data stored in your email account. A common choice is 12 months.
Many times people using a Windows-based computer can't open the files you send as attachments. You typically need to add the proper file name extension to correct this problem. A file name extension is the three or four letters, preceded by a period (.), that appear at the end of file names. For example, Windows(R) Office files have names that end in ".xls," ".doc," or ".ppt." This extension tells a Windows-based computer what program to use to open the file. When you select the Append file name extensions check box, Entourage will automatically add the correct extension to the names of files you attach to messages. To make this change for compatibility, open Entourage Preferences and select the Compose option. Check the option to Append file name extensions as shown below:
The use of an email signature can be a helpful way to let the recipient of your email message know who you are and how to contact you. To add a signature that will be appended to the end of your messages, click on the Tools menu and select Signatures from the list. In the Signatures window, highlight Standard and click on the Edit button to begin making changes to your signature.
The signature will contain two dashes by default. When creating your signature, it is advisable to keep it to only a few lines, but contain the most important contact information about yourself. A simple example is shown below. When you are finished editing your signature, you may simply close the editing and Signatures windows by clicking on the red button in the upper left corner of the window. If you are prompted to save any changes, accept the prompt to save.
