MS outlook not launching within New VDI environment

Encountered the following issue when standing up VDI Environment.

1.       Outlook was not launching.

2.       Checked with Exchange team and networking team on whether the mailboxes are created or not and all required ports are opened or not for outlook and lync to access as inbound and outbound access are tightly restricted between firewall.

3.       For Exchange team we found out that some mail accounts are created as deskless workers (outlook web access) they cannot use the outlook client.

4.       We checked common ports like 25(smtp), 135(msrpc), 443(https), 993(imaps), 995(pop3s), 7575, 7576, 7830 and dynamic ports range 60000+

5.       Checked for Lync port required are 5061 and 443 and made sure we opened a firewall request to network team to open the required outlook and lync by providing the server name and port numbers

6.       Exchange team changed the deskless workers to standard mailboxes (MBX=5GB; Type=EP2D)

Telnet test from the VDI desktop to 10.XX.XXX.XXX on ports 135, 443, 993 and 995 all worked fine.

However telnet tests on ports 80 and 25 failed.(Do we need it for outlook connectivity?)

SO I’m not sure if this is a firewall issue or an Outlook issue.

Telnet command : telnet 10.XX.XX.XX 135

7.       Firewall ports are opened Now(read the attached email chain). the final troubleshooting helped the issue resolved which is as follows.

8.       Under Citrix Policies on Xendesktop 7.6,  - “!ctx_localappdata!\Microsoft\Outlook” is in the Exclusion list – directories – Removed it from the policies

9.       This change helps to create a folder for users profile(wmantooth is the user name) location - D:\Users\CitrixProfiles\wmantooth.Domain\Win7x64\UPM_Profile\AppData\Local\Microsoft\Outlook\wmantooth - wmantooth.ost

10.   User logged into VDI Desktop and followed the attached instructions(Outlook access) and user was able to log into outlook.
