ItemAdd event is not triggered when importing a large number of contacts

[kia]

Hello,

When I tried to import (using the Import and Export option from the File
menu) a large number of contacts (over 1000) into the Contacts folder the
ItemAdd event is not triggered at all.

In the same circumstances when I tried to import only 10 contacts I saw that
the ItemAdd event was triggered for every contact item.
I have an Outlook plug-in and I want to perform some additional operations
for the newly added contacts, so I need to be notified when a contacts is
added.

Is there some kind of limitation in Outlook, or how can I resolve this
problem ?

Note: I monitorized the events with Outlook Spy.

Thanks,
K.I.

In general, more than 16 items at a time will cause ItemAdd and ItemRemove
to fail to fire.
