Short Description: Controls how many entrys are in the recent contacts view
There is a maximum number of people who can be in your Recent Contacts; the default is approximately 3000. (You or your administrator can change the maximum number of contacts allowed with the Notes.ini parameter DPAB_MAX_DIP_TABLE_SIZE=3000.)
If you have more than the maximum number of contacts, the people you communicate with the least will be deleted from your Recent Contacts whenever your Recent Contacts are updated, which happens approximately every seven days. If you do not have more than the maximum number of contacts, no contacts will be deleted.
Setting this entry to 1 or 2 would mean there is only one entry in the view! So that value is not a clever idea.
None (means 3.000 entrys)
There is no kown UI setting for this notes.ini variable. But you can specify this setting in the notes.ini settings tab of the configuration settings document.
