Error 0x80070057-00000000-00000000 Outlook Meeting Request
When you try to send a meeting request from Outlook you get the following error :
Your message did not reach some or all of the intended recipients.

This message could not be sent. Try sending the message again later, or contact your network administrator. Error is [0x80070057-00000000-00000000].
To fix this you need to ensure that the sender of the request has picked the address from the global address book or if that does not resolve the issue try a /cleanprofile or /cleanfreebusy and this should resolve the issue. I have seen this error on Outlook 2003 and 2007 so it may be on other version also.
