I will start by saying Im a web developer and my networking knowledge is very limited, please be patient =) . We dont have network/sysad in our company.
We are having problem with our connection. We cannot send outgoing email on our outlook UNLESS we restart the interface by pressing the disconnect button
(see picture). After restarting, the emails will be sent BUT after few minutes same problem occurs, then we have to restart again! We are also using google drive is unable to connect to google server (not sure if its because of frequent restarts we are doing)
by the way, we had this problem solved (kinda) for a month or two, everything is working fine until I pressed the disconnect button
. Then the problem starts occuring again until now.
Please note that we dont have any problem receiving emails. Only for outgoing.
We are using Sonicwall Model TZ 105
Other Info:
- Email Client: Outlook 2013/2016
- OS of Users: Windows 8/8.1/10
- Email Provider: Etisalat (local provider in United Arab Emirates)
- Outgoing Server: mailv.emirates.net.ae Port: 25
- Incoming Server: mailv.emirates.net.ae Port: 110
- SSL: we are not using it (not sure what to provide)
Update
When using cmd on host machine and try pinging the outgoing mail server Im having request timeout
response. But when pinging inside virtual machine (virtualbox) Im receiving different response (see image). When using mobile data
and ping the outgoing server mailv.emirates.net.ae
using host machine
then its successful. I've also tried different laptop and ping mailv.emirates.net.ae
they are successful.
