Hi Matt,

Thank you for writing to Aspose Support team.

We have tested this issue at our end and were not able to face any problem as you have mentioned. Can you please try the following test code that has actual credentials of a test account and let us know your feedback? Please share your sample code with us for further investigation in this regard.

Sample Code:

ImapClient client = new ImapClient(“outlook.office365.com”, 993, UserTwo@Aspose2016Mar.onmicrosoft.com", “Aspose1234”);

client.SecurityOptions = SecurityOptions.Auto;

client.SelectFolder(ImapFolderInfo.InBox, true);

Console.WriteLine(client.ListMessages().Count);
