Hint
For the Primary email address field use the other persons email address. As BFH-ACCOUNT please provide your own username (eg. 3-5 letters followed by a number).
Right click below your calendar list and select New Calendar.
Select On the Network.
Select Microsoft Exchange 2007/2010/2013.
Fill in a name for your new calendar. Uncheck Show Reminders and ensure to select none
for the E-Mail field.
A password may be asked. Provide your own password. It is recommended to let thunderbird remember your password because there are many calls to your online calendar without even having it open.
Press Next.
Press Finish.
