Outlook 365 Tips

Change the default address book

Open a new email message and click  on the "To" button

Your address book probably defaults to "All Users - ..."

You will need to hit the down arrow to the right of that and choose "Global Address Book" and then find the person you are looking for OR you can make "Global Address Book" the default by doing the following:

Click on the "Address Book" option on the far right of the ribbon

Click "Tools", then "Options"

Select "Start with Global Address List" if it is not already selected.

Click on the down arrow to the right of "Choose Automatically" and then select "Global Address List".

Click OK to close that dialog box.

Hit the X in the upper left to close the open dialog box.

You're done.

Now, when you start a new message and click the "To" button, the default Address Book will be the "Global Address List".

Keep Meeting Requests even after you've responded

In Outlook, click "File", then "Options"

Click "Mail"
