My client has a few Outlook 2013 contact groups with a few dozen people in each. The mail host has a limit of about 25 emails, but some of these groups are larger than that, and so the sending fails:
Server error: '550 sorry, too many recipients (#5.7.1)'
Are there any solutions to this problem that will allow my client to stay in Outlook?
(the mail host has an option for an email distribution list, but the client would prefer to maintain just one list in Outlook. There are also 3rd party services that allow him to send out emails, but this again requires maintaining a second list).
