We have mixed environment of Windows and Mac using Exchange 2007. All of the Mac users are using Outlook 2011, however success of email delivery for some people is getting delayed at times. Most of the time the email will deliver immediately. Other times,
the email will not be delivered for hours, or even as long a two weeks. My research has found many complaints on this issue but the consensus is seemingly pointing to a problem with
Exchange 2010, and not 2007. The cause of the delays and the fix is posted
here but it is only a fix for Exchange 2010. We plan on upgrading to Exchange 2013 within the next few months so my question is: Is there any known issues as described? Was the "fix" for 2010 part of 2013?
