You may have used a block or a repeating series of blocks in your agenda because you do not want your customers to be able to book during these periods. Do you want to delete a block like this?

This can be done quickly through your calender:
1. Calender
2. Double-click the block
3. Delete
4. Click "Delete"

Do you want to delete a whole series of repeating blocks?

1. Calender
2. Double-click on the block
3. Delete
4. Check the "Delete future blockeds" box
5. Click "Delete"

Now the entire series will be deleted from the block you double-clicked on.

Note: If you only have to remove a few blocks from the whole series of blocks, then do not check the "remove future blocks" check box.
