Title: Receiving Daily Errors Last modified: September 18, 2018 --- # Receiving Daily Errors * [jcd1006](https://wordpress.org/support/users/jcd1006/) * (@jcd1006) * [7 years, 8 months ago](https://wordpress.org/support/topic/receiving-daily-errors/) * Started receiving errors everyday on deliveries. Not all deliveries are erroring out. At times I can go in and resend the notification from the Gravity Form area and it works fine. Also will work if I resend notification from the SMTP area( however formatting is off). However, there are times I am unable to resend even from Gravity form area. Below are the most recent error messages * 5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message. 16.55847:32290000, 17.43559:0000000094000000000000000800000000000000, 20.52176:140F77840000101030020000, 20.50032:140F77847E1710103C020000, 0.35180: 02011330, 255.23226:52020000, 255.27962:0A000000, 255.27962:0E000000, 255.31418: 0201E165, 16.55847:BA000000, 17.43559:0000000068010000000000000200000000000000, 20.52176:140F7784000010100B002900, 20.50032:140F77847E17101003003600, 0.35180: C9000000, 255.23226:0A004100, 255.27962:0A000000, 255.27962:32000000, 255.17082: DC040000, 0.27745:0A006400, 4.21921:DC040000, 255.27962:FA000000, 255.1494:E9000000, 0.37692:0F010480, 0.37948:00000000, 5.33852:00000000534D545000304532, 4.56248: DC040000, 7.40748:010000000000010B31414342, 7.57132:000000000000000000000000, 1.63016:32000000, 4.39640:DC040000, 8.45434:C828A2389C207D4D95F3779105953BFC44000480, 5.10786:0000000031352E32302E313134332E3030303A424E * 5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message. 16.55847:6B2D0000, 17.43559:0000000094000000000000000200000000000000, 20.52176:140F77840000101030020000, 20.50032:140F77847E1710103C020000, 0.35180: 02011330, 255.23226:52020000, 255.27962:0A000000, 255.27962:0E000000, 255.31418: 0201E165, 16.55847:BA000000, 17.43559:0000000068010000000000000200000000000000, 20.52176:140F7784000010100B002900, 20.50032:140F77847E17101003003600, 0.35180: C9000000, 255.23226:0A004100, 255.27962:0A000000, 255.27962:32000000, 255.17082: DC040000, 0.27745:0A006400, 4.21921:DC040000, 255.27962:FA000000, 255.1494:E9000000, 0.37692:0F010480, 0.37948:FE7F0600, 5.33852:00000000534D545000010480, 4.56248: DC040000, 7.40748:010000000000010B30303A42, 7.57132:00000000000000003A663537, 1.63016:32000000, 4.39640:DC040000, 8.45434:C828A2389C207D4D95F3779105953BFC0F010480, 5.10786:0000000031352E32302E313134332E3030303A424E * 5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message. 16.55847:34290000, 17.43559:0000000094000000000000000300000000000000, 20.52176:140F7784000010100A00A283, 20.50032:140F77847E17101003000B37, 0.35180: B6000000, 255.23226:0A000137, 255.27962:0A000000, 255.27962:0E000000, 255.31418: C0000000, 16.55847:BA000000, 17.43559:0000000068010000000000000100000000000000, 20.52176:140F778400001010CF000000, 20.50032:140F77847E171010D4000000, 0.35180: 0A00E982, 255.23226:D9000000, 255.27962:0A000000, 255.27962:32000000, 255.17082: DC040000, 0.27745:E3000000, 4.21921:DC040000, 255.27962:FA000000, 255.1494:0A006D85, 0.37692:09010480, 0.37948:01000000, 5.33852:00000000534D545000000001, 4.56248: DC040000, 7.40748:010000000000010B09010480, 7.57132:0000000000000000AE636B6A, 1.63016:32000000, 4.39640:DC040000, 8.45434:C828A2389C207D4D95F3779105953BFC31314D42, 5.10786:0000000031352E32302E313134332E3030303A424E Viewing 6 replies - 1 through 6 (of 6 total) * [Russ](https://wordpress.org/support/users/gfxdesigner/) * (@gfxdesigner) * [7 years, 8 months ago](https://wordpress.org/support/topic/receiving-daily-errors/#post-10705303) * I have been getting the same errors from one of my clients that uses Office 365 for authentication. Are you also using Office 365? * My clients using other mail servers aren’t getting this error, so I assume something changed with Office 365 to create these errors. * Thread Starter [jcd1006](https://wordpress.org/support/users/jcd1006/) * (@jcd1006) * [7 years, 8 months ago](https://wordpress.org/support/topic/receiving-daily-errors/#post-10705328) * They are using Office 365. I noticed the same thing, no other issues with other clients on various hosting and email systems. * [Russ](https://wordpress.org/support/users/gfxdesigner/) * (@gfxdesigner) * [7 years, 8 months ago](https://wordpress.org/support/topic/receiving-daily-errors/#post-10705342) * The weird thing is if I “Send a Test Message” via the Post SMTP admin screen, it actually goes through. So I am not sure why it would fail on submitting with a form. * [yehudah](https://wordpress.org/support/users/yehudah/) * (@yehudah) * [7 years, 8 months ago](https://wordpress.org/support/topic/receiving-daily-errors/#post-10706054) * Hi [@jcd1006](https://wordpress.org/support/users/jcd1006/) and [@gfxdesigner](https://wordpress.org/support/users/gfxdesigner/), * As I see it your form is letting setup a from address that office 365 is rejecting. * can you check the email log and see what is the from address in one of the failed emails? * [yehudah](https://wordpress.org/support/users/yehudah/) * (@yehudah) * [7 years, 8 months ago](https://wordpress.org/support/topic/receiving-daily-errors/#post-10707163) * Hi, * Wrote a small guide with recommended steps: [https://postmansmtp.com/storedrv-submission-exceptionsendasdeniedexception-mapiexceptionsendasdenied/](https://postmansmtp.com/storedrv-submission-exceptionsendasdeniedexception-mapiexceptionsendasdenied/) * [Russ](https://wordpress.org/support/users/gfxdesigner/) * (@gfxdesigner) * [7 years, 8 months ago](https://wordpress.org/support/topic/receiving-daily-errors/#post-10707961) * That worked! Thank you for the update. * It’s a bummer that Office 365 is strict on the “from”. I understand it’s because of preventing spoofing, but it makes it so convenient in forms to have the reply- to be the actual form submitter.
