If you are using more than one service to manage your schedule, it's likely your appointments might be duplicated or even overlap. To prevent this, it is adviceable to link the two accounts. For instance, if you use Doodle and Outlook, then Doodle lets you link your Doodle account with Google, Outlook and iCal, so you can keep your schedule updated via all of the services. Here’s how you can link your Doodle account with Outlook 2007 or 2010.
On the Doodle homepage, you will see the ‘Automatically sync appointments to your calendar’ option. Clicking on it will show a couple of options. Here, click on the ‘Connect with Outlook’ option. Before proceeding, you will have to sign up for a Doodle account if you haven’t got one. Now, download the file and follow the instructions for the setup. You will have to restart your machine. When you next start Outlook, you will be required to log-in to your Doodle account as well. You will also have to authorize the app to access your Outlook account. You can select the Outlook calendar you want to connect with Doodle. You can even control the amount of information that you wish to share with Doodle. Once the accounts are linked, you can search for a particular appointment directly through the Outlook calendar search option.
