Dear Fellow

 

I have recently encounter a problem much similar to following.

https://docs.microsoft.com/en-us/answers/questions/394418/exchange-messages-encoding-error.html

 

My situation however,

1) Some not readable Japanese characters email appears correctly after applying disclaimer using exchange transport rule (new email).

2) 1 of the non problem problematic sender starts having problem after applying the disclaimer (disclaimer was in html format).

 

I have applied <add key="DisableDetectEncodingFromMetaTag" value="True"> as suggested from following links, however its not helping for situation 2) as above.

https://docs.microsoft.com/en-us/answers/questions/394418/exchange-messages-encoding-error.html

 

Non readable character looks like following

!&!& (Bァ $B!& (B

 

 

Any suggestion is greatly appreciated. Thanks!

This specific problem was not because of Exchange it self but rather the antivirus for exchange which has the capability of altering html at transport level (transport agent).
