(1) In your Outlook Calendar click on View > Current View > By Category

(2) Delete old Events
You can sort the upcoming list by date and delete old appointments. Depending on how long you’ve been using Outlook these entries might reach long into the past. Be careful not to delete recurring events as you might kill the entire series.

(3) Delete “big” appointments
This list doesn’t display the size of appointments by default, but you can easily add the Size field to the top of the table.


Right click on one of the header fields (“Subject”, “Location” etc.) and click on Customize Current View. In the upcoming Window click on Fields.

(4) Select Size and click on the Add -> Button

(5) Sort the list by Size and delete large attachments.

Voilà thats it, you’re done.

Bonus Tip:

There is actually another method to find large appointments in the Calendar.

1. In your Outlook Calendar menu, click on Tools, select Find, then Advanced Find.
2. 2. On the More Choices tab, at the bottom under Size, select the greater than option
3. 3. Input the maximum amount you want to see, for example 100.
