Thank you @DustinB3403 , but unfortunately i have tried all of this before and maybe more than this but without any result

because i have an application that record voip calls, it need to catch the whole traffic, i configured a mirroring port on my switch that send all traffic to this VM, but unfortunately i was unable to get promiscuous mode working

i still cannot get this done, after reading some documentation i realized that xenserver has promiscuous mode issue in 6.5 and people complaining about that in citrix official support website,
i think it is time to shift to vmware ESXI, i hope i can manage myself with it

ovs-vsctl show

tcpdump -i eth1
sniff all traffic
tcpdump -i xenbr1
sniff all traffic
tcpdump -i vif2
tcpdump: vif2: No such device exists
(SIOCGIFHWADDR: No such device)

something weird, i have only these interfaces :
eth0 eth1 lo vif1 vif2 xenbr0 xenbr1

i think normally i should have something like : vif0.1, vif0.2 bridged with eth0
and vif1.1, vif1.2 bridged with eth1
???

also xenbr1 catch all traffic

knowing that PIF1 get the whole traffic (i checked that by tcpdump -i eth1)
the problem reside in VIF1, PIF1 not mirroring the traffic ti VIF1,

Hi everybody

i have xenserver Host with 2 NIC, i installed 2 VM on it, i bridged the 2 PIF to one VM , this VM has now 2 VIF, VIF0 bridged with PIF0 and VIF1 bridged with PIF1,
PIF0 is connected to the LAN, PIF1 is connected to a mirroring port on the switch (sniffing all traffic ti record voip calls)

i have already execute the following command :

xe pif-param-set uuid=<uuid_of_pif> other-config:promiscuous="true"
xe pif-param-list uuid=<uuid_of_pif>

xe vif-param-set uuid=<uuid_of_vif> other-config:promiscuous="true"
xe vif-param-list uuid=<uuid_of_vif>

xe vif-unplug uuid=<uuid_of_vif>
xe vif-plug uuid=<uuid_of_vif>

i tried both :
xe-switch-network-backend bridge
xe-switch-network-backend openvswitch

it is so frustrating, i spend hours in this

i just checked that, i found that my system local was arabic, i mean that the email language is the same as my system local language

But what was the sender's system setting? That should not matter in an application such as Outlook, but it is always something I try to check once all the basic troubleshooting steps prove fruitless.

yes you are right, i have to check that also, but if only the sender is someone who is from the users

for example : X send email to A and B and C ....only A have this issue

So, the question then is how do A's settings differ from B and C's? In particular, look at the language, formatting and font settings. Also check whether A has any Outlook add-ins installed than B and C do not - especially antivirus add-ins.

all the users have kaspersky spam filtering add-in

Obviously updates are needed here first, but if the issue persists, it can very likely be due to the original item being sent in a very specific encoding.

I run into this often with file names when people in Japan send a document.

The only solution I have it so retype the name or change my system base language.

Here is how I have my desktop setup for example.

Similar problem time ago.

Check Internet Explorer Version, try to update to the last one.

i will upgrade my IE8 to 11, and i will inform you whether the issue is still happening or nor

thank

in windows 7,

where i can check in outlook ??is there any place in outlook to check in ??

because we cannot diagnosis the problem because it occur then vanish ....

the worst problem ever is the problem that occur only sometimes,

the big issue here is that this problem doesn't happen all the time but sometimes, maybe 1 time in a week

the issue reside in outlook, but i cannot put my feet on it

for example : X send email to A and B and C ....
only A have this issue, other people receive the email in clear text
A has 2 way of reading emails : outlook 2007 and webmail, he have issue only when he open email in outlook, as for webmail the email is OK
