Hello,
I’m using Outlook 2013 Professional Plus on Windows 7 Ultimate (both 64 bit). I recently installed Gmail POP3 account after using IMAP for a year or two on Office 2010. For some peculiar reason, it seems that Outlook having no problems with sending out “regular” email messages, but fails to send meeting requests (nor meeting updates). Every time I tried to send something, I receive the error message: Error 0x800CCC13 (“Cannot connect to the network. Verify your network connection or modem”).
The problem is that I tried to start Office in safe mode, changed to another SMTP server, Changed to use SMTP with SSL, changed SMTP ports, disabled all my add-ins, deleted and recreated my mail account all over again, and even tried to repaired outlook through the control panel. Please assist :/
