After a week of having duplicate calendars on my BlackBerry driving me crazy, I did some research to figure out what was going on. (This is not original information, but is good to have if you find yourself in my situation.)
In order to update to the most current version of BlackBerry OS on your device, you’re best to install the BlackBerry Desktop Manager. Having completed this (including the OS update) a second calendar showed up on my device. However there were enough other features to the new OS to keep me occupied so the calendar issue went to the back of my mind for a while. That was, until I started to get duplicate updates for every event I had. That got old fast.
After trying the calendar options, finding I could really only change the color for the calendars I had already installed, I found that my answer was not in the device options.
After reading quite a few other web postings on the subject, there were many recommendations about deleting service books for all CICAL entries, etc. But that too wasn’t the answer.
If you have two calendars, here is the most direct way to consolidate them into a single calendar (assuming that is your goal):
- Open the Calendar.
- Press the menu key.
- Choose Options
- Type MOVE on the keypad.
- You will be asked to move all appointments in the base system calendar. Choose YES to accept moving all entries in the Device Default calendar to the default active calendar.
- Perform a hard reset of the BlackBerry by taking the battery out while the phone is still powered on and placing it back in.
This operation will move all calendar entries existing on the Device Default calendar to the active calendar shown in Options > Advanced Options > Default Services.
At this point, I was good. And in fact this may be all you need to do also. However if you had this issue because you have two calendars on two separate email addresses, you may need to do the following:
- Go to Options > Advanced Options > Default Services.
- Verify the correct email address is shown for Calendar [CICAL].
- Press the back arrow and save the changes if prompted.
- In the Advanced Options menu, choose Service Book.
- Highlight the entry for the calendar you do not want. This will appear as email@example.com [CICAL].
- Press the menu key and choose Delete.
When deleting a CICAL, any calendar entries associated with it are moved to a Device Default calendar.
Hopefully this is helpful.
