About Enterprise user Mailboxes "554.5.7.1 Access denied" when posting messages outward

Yesterday, a colleague contacted said that their mailbox can not send mail to the public email, while other colleagues are normal, after receiving this failure report, I in the user client tried to send to the public mailbox, confirm that the user mentioned problem does exist, the error is as follows:

650) this.width=650; "title=" image "style=" border-top:0px;border-right:0px;background-image:none;border-bottom:0 px;padding-top:0px;padding-left:0px;border-left:0px;padding-right:0px; "border=" 0 "alt=" image "src=" http:// S3.51cto.com/wyfs02/m01/78/bb/wkiom1acrror1zjlaacscqg5a_y494.png "height=" 324 "/>

When you see 554.5.7.1 Error, depending on the experience should be a configuration problem caused, and generally common in the SMTP authentication problem caused, OK next I will look at the user's mailbox configuration:

650) this.width=650; "title=" image "style=" border-top:0px;border-right:0px;background-image:none;border-bottom:0 px;padding-top:0px;padding-left:0px;border-left:0px;padding-right:0px; "border=" 0 "alt=" image "src=" http:// S3.51cto.com/wyfs02/m01/78/bc/wkiom1acrrisdzwiaaskqgvvi0e628.png "height=" 397 "/>

Oh? There is no tick here ...., because the user is configured to pop mode, the normal configuration we will tick this, and here is not checked, so we put this tick, check the completion, and then test to send the public network mailbox, has been able to send the normal.

Although the problem is very simple, but I still write out, IT staff for the user configuration is still to remember the standard method of configuration ah.

It reminds me of a colleague who used to send full-time mail to the public account, the sending client did not see any delivery failure error, but sent to the message is not enough, all the staff confiscated, the sender has not delivered the failure, the final inspection is also due to the configuration of the pop mode, and did not check the contents of the display, When checked, it's normal.
