Hi and Welcome to the Community!
I find nothing exact when searching the public KBs...perhaps you will have better luck:
Otherwise, I suggest this thread:
It starts with a process for cleanly starting over, and there is some discussion, and there is also a post (15) with links to older Desktop Software versions, if those are needed. Note that this is not, by any means, guaranteed to work...but it has worked for many to resolve issues they are having.
It may well be that you have corruption in either your Outlook databases or perhaps even your on-device databases. You might want to research, via Microsoft forums, the potential of the culprit being Outlook.
You also should ensure you take a good backup of your BB, just in case it turns out to be the device databases that have the corruption.
