Destination Users not getting emails....

Is anything related to exchange appearing in the logs within the hostserverin folder? You may find more detail on the issue there

This is happneing in Exchange, or it is happning in the K2 configuraton to Exchange.  Most likely the former.

Work with ayou Exchange Administrator to see if messages are going.  You may also have to check MSMQ services, gte help form your Opertations team, to see if messages are trapped in there.  If the issue is not in Exchange, then open a Support ticket to troubleshoot the MSMQ possbilities.

Hi Sharpharp1,

Did you make changes to the process and deploy? Did you make any changes to the email that gets sent? Since things are still working in other processes, you can check the Host Server logs for any errors that might show up when an email is sent. Client event notifications don't break the workflow if they fail, unlike email events.

You can also check the EventBus.ClientRecorderError table in the K2 database to see if something is happening when the messages are going through the message queues. (For instance, if there are issues with SmartObjects contained within the email subject or body, the errors will usually end up in this table)

Hi all,

Thanks for the responses, the mailbox of the users is fine because they receive approval emails from other forms/processes i have.

It's just this one that has stopped working.
I will continue to try other ways today to get this working,

@Emily, found a few of these in the hostlogs: ,"Error","IdentityService","64007","IdentityServiceError","IdentityService.ProviderCacheIdentity:RoleProvider.GetGroup","64007 Provider did not return a result for K2:domainMyUser

That is very strange that the issue seems related to one specific process... can you update that process to (temporarily) only assign the task to you, and see if you get the e-mail when it is simplified in this way? Maybe it is having an issue with one of the participants on this particular task.
