Outlook - Operation Failed message when sending mail
Posted on 2013-01-28
We have some users that use Outlook 2010 and have recently changed from online mode (Exchange 2010) to cache mode.
For the most part. things are working well, however some users occasionally get an error dialog when trying to send an email message. The error message simply says 'Operation Failed' and the message will not send. Typically if they save it as a 'draft' and then open and close Outlook and then resend it from the drafts folder it will send ok.
It is becoming a nuisance and not sure why it is only happening to 2-3 users out of the 15-20 we recently converted to cache mode....
