Hi, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your issues. Are you using a Windows computer or a Mac?
What version of Outlook are you using -- 2003, 2007, 2010, 2013 or 2016?
Also, how exactly you get this error message? When you open Outlook? When you send an email?
Please let me know by replying to me here so that I can help you further.
Hi, thank you for writing back with that information. So is this problem happening in your Windows computer? Or in your iPhone?
