This generally happens when you need to send "New" service books to your BlackBerry and have multiple e-mail addresses setup.
It is in my experience that the "New" service books change the "Default" address you had already setup. This is very frustrating, but rest assure it is NOT a Theme issue. It is a service book issue!
To check and see if this is what is happening you need to verify your default address for E-Mail and Calendar items. To do this please follow the steps below:
- From the home screen hit the "Menu" button. The Menu button is the BlackBerry Logo just to the left of the trackball on keypad phones and just to the left of the "Escape" [the sideways U with the arrow on it] on Touch Screen devices.
- Now find "Options", usually the icon with a wrench on it.
- Now locate the "Advanced Options" line item.
- Highlight it and click the trackball or touch the screen to enter.
- Now locate the "Default Services" line item
- Highlight it and click the trackball or touch the screen to enter.
- Here you will see your "Default Services", Make sure these are what you want them to be.
- If they are not, correct them and save before you exit.
- Now see if your calendar displays correctly.
You may also want to have a look around in the Calendar itself. This is done by going into your Calendar App, hitting menu, going to options and looking around.
If the Calendar still does not display correctly, please locate the manual that came with your device or use your favorite search engine to research your issue. I may do a "How To" fix this sometime, but as of yet I have not typed one up.
