i am running into an issue and not quite sure where to go next...
the situation: Widnows 7 pro, Outlook 2010 (cached mode), mail hosted by Microsoft
after a few minutes, when sending mail, nothing actually gets sent, outlook does not complain (thinks all is updated)
i can receive mails, but not send... it works again for a few minutes when i close and restart outlook...
this happens over WIFI and wired network..
i do not see this problem when on other networks.... (like airports etc)
my IT reloaded my cached email, but that did not fix it...
