Searching emails accounts for the domain microsoft.com in a PGP server, here it's not necessary to specify the limit.

./theharvester.py -d microsoft.com -b pgp

Searching for user names that works in the company microsoft, we use google as search engine, so we need to specify the limit of results we want to use:

./theharvester.py -d microsoft.com -l 200 -b linkedin

Searching in all sources at the same time, with a limit of 200 results:

./theHarvester.py -d microsoft.com -l 200 -b all
