Populate HomeFax and BusinessFax. MapiContact PST file

I'm currently reviewing this product and trying to export contacts. I'm having problems populating the following fields

This is what I am trying:
mapiContact.ElectronicAddresses.HomeFax.FaxNumber = "123456";
mapiContact.ElectronicAddresses.BusinessFax.FaxNumber = "123456";

is this a limitation in the trial?

Many thanks

Hi Ashley,

Thank you for writing to Aspose support team.

We have tested this issue at our end and everything works fine. The generated MSG file has both the fax numbers as specified. In Outlook, you need to select Business Fax and Home Fax to view these numbers. Please try it using the latest version of Aspose.Email for .NET 5.5.0 and let us know your feedback.


I’ve upgraded to the latest version and tried the following, still with no success:
MapiContact mapiContact = new MapiContact();
mapiContact.ElectronicAddresses.HomeFax.FaxNumber = “Home Fax”;
mapiContact.ElectronicAddresses.BusinessFax.FaxNumber = “Buiness Fax”;
mapiContact.Telephones.BusinessTelephoneNumber = “Office Number”;
mapiContact.Save(@“C:\Users\Test\Desktop\Pst Import\test.vcf”);

This is what I get:

It appears Business Fax gets entered into OtherFax?

Am I missing something?

This bug seems to have reappeared in version
My code (the example is the same as yours, so ty for the legwork webfort ;)) gives me the same result - no fax numbers being committed to the pst file at all.

Here is my code - emails 1 thru 3 do commit, but the fax numbers are nowhere to be found:

            contact.ElectronicAddresses = new MapiContactElectronicAddressPropertySet
                Email1 = "",
                Email2 = "",
                Email3 = "",
                BusinessFax = "1111111111",
                HomeFax = "2222222222",
                PrimaryFax = "3333333333"

Can you run a test and confirm this please?

Please try setting the fax numbers explicitly as in attached sample project:

                contact.ElectronicAddresses.Email1 = "";
                contact.ElectronicAddresses.BusinessFax.FaxNumber = "1111111111";
                contact.ElectronicAddresses.HomeFax.FaxNumber = "2222222222";
