3cx webmeeting emails intermittently not being received.

[FridayIT]

Good afternoon,

We are experiencing an issue where invites are intermittently not being sent for new meeting creations. for example, if I create a meeting and invite 5 clients, 3 emails get sent and none are sent to the other 2. previously we were using 3cx's SMTP server. as a test we created a 365 email address and used that to send a reproduced this with the same issue.

Firewall check is green

webmeeting sync is showing green. firewall tests do not show any blocked packets over port 587. the emails that is "misses" are also not consistent. so email1 may not receive the invite, but may receive the cancelation. I ran a few tests, and about 80% of the time at least one invitee is missed.

I checked the outgoing mail tracking and it is also not showing the message. it also does not show in the mailbox's sent items either.

Has anyone had similar issues with this recently?

All emails are sent from your 3CX itself, no from the cloud platform. You can check the system service log for your install for more information related to SMTP activity or the logs of your SMTP service provider.

I can see all the test email addresses listed in the logs, I opened a official support ticket to get some assistance with this .

Hi, any answer to this question yet. I have a client with the same problem. Some email invites do not arrive, others do. Results vary with the same e-mail addresses.

Working with 3cx on providing logs. We had a P2P link go down today so that has taken priority.
