I am able to read the ost file format from outlook , but its only feteching 50 recods from Inbox or any folder. I have added this dll from the Nuget package manager in my project . So for free dll it will show only 50 records ? Can you help me how to resolve this issue ?
Yes, you are facing evaluation limitations due to which limited number of records are shown from OST. You can get a 30-day temporary license free of cost to try the API without any limitations. Please let us know if we can be of any additional help to you in this regard.
