folder.getContents does not get all the mails in the folder

I’m trying to extract all messages from a pst file, the Pst file contains a lot of mails something like 1800 mails in the sent items folder, but the folderInof.getContents() return mail collection of only 50 items, I’m using the free trial version is that has something to do with the problem ?

@nasty6666,
Welcome to our community! Using the trial version of Aspose.Email, only 50 emails can be extracted from a folder in a PST file. Please also look at other limitations: Evaluation Version Limitations.
