Emailing vSZ guest passes fails

[steve_bluck]

We've moved from an on-prem Exchange server to O365, I've changed the System >> General Settings >> SMTP Server to the appropriate O365 SMTP server host as per option 2 of https://docs.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-dev...;

Alerts are being sent after the changes e.g. AP's down etc. but emailing of guest passes fails. The only error I can find is in Events & Alarms >> Events:
Code | Type | Severity | Activity
982 | Email sent failed  | Warning | [IDM] sent email to [name@domain.com] failed.
The guest passes are only sent to internal organization users.
We are on Controller version: 5.1.2.0.302
What am I missing? Is there another place to setup SMTP server?

In Exchange you have a setting to allow a connector to send emails to internal or external addresses.

Thanks, but the issue we have is that alert emails are working via the new O365 server but sending of guest passes is not -even to those users that receive alerts e.g. this comes through via O365 without issue:

Emailing of guest passes now working after a scheduled update to 5.2.1.0.515.

My guess is just needed a reboot but under our change system this would have taken longer time to organise than the already approved upgrade 🙂

Be nice to know what service to restart to force the SMTP update -anyone from Ruckus want to chime in?
