Change the email address to use with each calendar
If you have multiple calendars on your BlackBerry device, you can set a different email address for each
calendar. When you create an event in a specific calendar, invitations are sent using the email address
that you assigned to that calendar.
The email address that you use must already be added to your device. Some accounts don't allow you
to change the email address (for example, your work account).
1. In the Calendar app, swipe down from the top of the screen.
2. Tap > Meeting Invitation Settings.
3. Beneath a calendar, in the drop-down list, tap an email address.
