SYMPTOMS
The MSExchangeMTA service may stop unexpectedly with an "access violation" error message and cannot be restarted. When you manually start the service, it stops responding with the following call stack in the dump file: FramePtr RetAddr   Param1   Param2   Param3   Function Name 010cf0f4 00410e6f  010cf11c 00000000 00000000 EMSMTA!odpinaat+0x6b 010cf134 0040b5fd  012cfd70 00000000 00000001 EMSMTA!odpbcfra+0x9a 010cf168 0048d959  010cf270 00000001 00000000 EMSMTA!odplfarb+0x12c 010cf268 0048d406  00270001 010cf288 010cfa67 EMSMTA!odpgique+0x157({...}) 010cfa70 0048c5f7  00676639 010cfee5 00000004 EMSMTA!odpgimai+0xc50 010cfc30 0048ba7d  010cff14 00688dda 00000000 EMSMTA!odpinday+0x2cf 010cff2c 00482cd9  77f0178b 77f1c661 00134ea8 EMSMTA!odpgmtin+0xb0c 010cff94 0048225a  77f9d850 00134ea8 0000017c EMSMTA!sbpwinit+0xa77 010cffa8 77dd8bec  00000001 00134eb0 ffffffff EMSMTA!sbpisvep+0xcf In addition, MTACHECK does not recover the issue when it occurs.

CAUSE
This behavior occurs because the working queue object (usually 00000027) is damaged. When the recovery procedure attempts to recover the object, the object is wrongly regarded as a damaged message. This occurs because the property array of a queue object is different than that of a message object. The later reference to the property array causes the "access violation" error message.
