I have tried to re-produce the scenario by reading a large PST file (size 3GB) having around hundreds of messages and it took about 58 milliseconds to load here. My test system memory is 3GB and its a 32 bit system.
Could you please send us the source messages which can be used to create the PST and then test the scenario mentioned above? It will help us to observe the issue and provide assistance as soon as possible.
I think the issue is related to attachments. Can you create email with large attachments(>40m) and add 20 of the emails to existing PST file ? I can not send you our original test PST file because of privacy concern. I have to create a fake one. Maybe it is easier for you to do it.
I have re-tested this issue on a 64-bit system at my end with the latest version of Aspose.Email for Java 4.4.0 but was still unable to face any such issue. This time I have created a PST file with a sample message that has 104 MB attachment in it. The message has been added to the PST 25+ times as per your advice. The saved PST was reloaded and no such exception was faced. It seems that the issue is specific to your environment or specific PST which we’ll be in need of to reproduce this issue at our end and assist you accordingly.
Could you please try at your end as shown here and let us know your feedback?
PS: My system has 8GB of Ram and windows 7 installed on it.
Aspose File attachment doesn’t allow to upload a file larger in size than 10 MB. Please upload it to some free online storage space such as Google Driver, Sky Drive or Dropbox and provide us with the download link of the file here. We’ll download the file for our investigation and assist you further.
PS: If the data is of private nature, you may mark this thread as private so that it is not accessible to users other than Aspose staff.
I am unable to download this file as the download process breaks after some time. I would request you to please split the file in small parts (this can be done using Winrar) and re-upload it so that it can be downloaded at my end. We appreciate your cooperation in this regard.
The download is currently in process. We’ll update you here once the download is complete and we investigate the issue at our end. If we face any issue with the download, we’ll write back to you.
