I have seen this problem mentioned a couple of times on the forums, and tried the solutions suggested (fixing permissions on all drives, clearing cache on the inbox folders etc..), none of which have worked.

My copy of Outlook has stopped adding email address' to the auto-complete memory. It remembers all the address' before a certain point, but has not added any new ones after this point, which is incredibly annoying and time consuming.

Does anyone have any idea why this might be? Or any potential fixes for this incredibly annoying issue?
