findallpeople in the ewsManage.py use m:FindPeople:

 <m:IndexedPageItemView BasePoint="Beginning" MaxEntriesReturned="1000" Offset="0"/>

You can just set the "offset" to 1000 for the next search.

And my code avoids the bug in this way:

https://github.com/3gstudent/Homework-of-Python/blob/master/ewsManage.py#L1275

Each letter is used as the search criteria and this will narrow the search results.

If the scope is still insufficient, the scope can be reduced again.

Like this:

            for i in range(97,123):
                for j in range(97,123):  
                	ewsManage_findallpeople(sys.argv[1], int(sys.argv[2]), sys.argv[3], sys.argv[4], sys.argv[5], sys.argv[6], chr(i))
