The Outlook toolbar lets users make VoIP phone calls to phone numbers stored in their address book without leaving the application.
The beta versions of the two applications were posted on Skype's website last week, but the code still contains some bugs.
The Outlook plug-in, for instance, offers to omit the '0' in area codes as is needed with international calls to many European countries. Instead of removing just the first zero, however, it deletes all of them resulting in a failed connection.
A Skype spokeswoman declined to give a projected release date for the final version of the tools, saying that Skype will collect user feedback to determine any necessary changes.
