URGENT Outlook clients Cannot access exhange 2010 server
Came in yesterday to our mail server playing up outlook clients could not connect to it.
From the server console I can connect to it & use logmein, I can browse the web etc. but cannot VNC to it or get outlook client to connect, or connect via telnet.
the windows firewall has been turned off with all settings to allow no difference. I can also access webmail on the server console but not from a pc.
All incoming connectivity is being blocked???
Has been escalated to Microsoft as business critical...still waiting, so I thought I'd better get the experts involved...come on guys don't let me down

Would you restart all Exchange services and check again. also do you have any HLB or NLB in between, if yes, restart that too and check.

Server has been restarted numerous times. Still the same.. can do anything from the server out but nothing inbound
HLB NLB???
HLB NLB???
ASKER
Domain controllers have been restarted as well

All other servers working fine....
HLB: Hardware load Balancer
NLB: Network Load Balancer
Normally there are two main reason for outlook connectivity issue:
1) DNS Setting or wrong Subnet
2) Office customization. (check if you have any .prf file in user machine, if yes open it with notepad and check which server it is pointing)
Starting check both these two items.
Also run ExBPA tool and check for any errors.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Can you connect to the server in any other way? Remote desktop, file shares etc.
If not, then it's nothing to do with Exchange. Windows Firewall or AntiVirus - or networking? Internal DNS?
