First of all, please let us know if you can replicate this behavior using the same mail addresses / number of addresses by using the Outlook Connector or if it was a one time issue.
Secondly let’s see if the problem is related to Outlook Connector or not by checking if by using same external e-mails you encounter this problem with Outlook setup with the IMAP protocol without using the Outlook Connector.
By default, these types of errors are related to the remote serverver response and the message normally is provided by the remote server.
First.
Happens multiple times daily since the deployment of Outlook Connector with different / multiple (x nos.) of email addresses sending using Outlook Connector.
Second.
Yeah with IMAP there is no problem will all outgoing emails. Only happens with Outlook Connector.
Third.
The thing is the receiving servers received the email properly even we receive the bounce back message.
Outlook Connector installed on Outlook 2016.
IMAP installed in Outlook 2016 and in TB.
Also we check all other forums related to this errors about contact properties etc. (MAILTO to SMTP on Internet Type)
Axigen Connector saves correctly and with properties SMTP on each contacts.
We are in critical stage with our customer to break. Because right now they are comparing other clients that are using Exchange Server without any issues using Outlook.
Please note that having an account used by 20 users is not an usual setup, however in order to further investigate this, please provide us a screenshot with the WebAdmin > Domains & Accounts > Manage Accounts > Edit on this particular Account > Quotas and Restrictions tab under the “Sessions” section.
It is now obvious that this issue should be checked from the IMAP, PROCESSING and SMTP module logs at Protocol Communication.
You may maximize the logs for these modules from:
WebAdmin > Services > IMAP > Logging section
WebAdmin > Services > SMTP Sending > Logging section
WebAdmin > Queue > Processing > Logging section
and as soon as this behavior is encountered please attach to your response the SMTP-OUT, IMAP and PROCESSING module logs that cover the time frame of this behavior. You will also need to mention the sending address and the recipients.
Nevertheless this type of investigation is better traced and handled via the support channel wich can be reached by sending an e-mail to support(at)axigen.com - also having your Registration code mentioned in the subject or just by opening it from WebAdmin > Contact Support:
Please find attach Undeliverable message. I manage to get all details on 1 due to the fact that It was a busy day to get and filter all 1by1 all the undeliverable.
Please note that even receiving this undeliverable the recipients properly received the mail.
Hope you can help us sort it out this issue. Atleast 10(different emails) daily we are getting this.
As we can’t see any errors in the Axigen log files, please use a machine that hasn’t disabled the creation of the OLK logs, replicate this behavior, attach the Outlook Connector Synclogs to your response and mention the time-frame /screenshot of this behavior.
We discontinued using Outlook Connector as it gave us more problems and shifted back to IMAP. Hope in near future your development team will find more bugs and try to fix them.
