CRM 2013 Sync Error RRS feed

  • Question

  • All,

    I have recently been asked to look over a Dynamics CRM 2013 install which is suffering some problems. At the moment its being trialled ahead of a full deployment and so we don’t have many active users. Two users have an ongoing issue with the sync of appointments, contacts and tasks. Within the portal, under Settings > Email Configuration > Email-Server-Profile > Alerts I am seeing the following:


    An internal Microsoft Dynamics CRM error occurred while synchronizing appointments, contacts, and tasks for the mailbox _User_. The mailbox has been disabled for synchronizing appointments, contacts and tasks and the owner of the associated email server profile _Profile_ has been notified.


    As the message is not overly informative I have enabled tracing to get some more detail, having played around a bit I think I have narrowed the relevant message down to the following:

    I have tried researching different elements of this error to little avail and so now hope someone here can provide some answers! I did not set this system up and am by no means an expert on the product therefore this may well be some small detail somewhere that’s been missed.

  • My first thought is there is something wrong with that mailbox. It looks like the GUID for that mailbox is missing somehow? Is that mailbox on a separate Exchange server, or is it an older mailbox that may have been through an Exchange migration/upgrade? I'd start by looking at the history of that mailbox and see if there is something different about it.

  • Hi,

    We have the same error in async log when we test the sync of appointments, contacts and tasks.

    (How) Did you fix this?

    Kind regards,

  • So something else I remembered about errors like this, sometimes they are caused by invalid characters in Outlook events.  In once case for a client of mine, a three year old recurring appointment had some kind of bad data .  The appointment had to be removed in its entirety from all mailboxes before things would actually work.

    Don't know if that's something happening here, but it's worth checking if you have an Exchange guru around.

  • Just a quick glance through the error message.

    <Message>subscriptionclients with clientid 6dafafb4-da51-e311-93f0-00155d02cf2f doesn't exist</Message>

    If they are using the Outlook client, have then try reconfiguring it to create a new subscription for syncing.

  • Hi Jason,

    She is not using Outlook client. I have enabled few other users and appointments are working fine but only for her account it is throwing. I have found following tables and noticed that there are records for users whose appointment are but there is not any record for her.

    SELECT sc.ClientId, sc.MachineName, sc.SubscriptionId, sc.IsPrimaryClient, sc.SubscriptionClientId FROM SubscriptionClients sc  

    SELECT  s.SubscriptionId,s.SubscriptionId, s.SystemUserId, s.MachineName, s.LastSyncStartedOn, s.SyncEntryTableName, s.SubscriptionType, s.CompletedSyncStartedOn  FROM [Subscription] s 

    Can you please confirm where clientID is coming from in SubscriptionClients table?

    Many Thanks

  • Hi

    I have resolved this issue after resetting ExchangeSyncStateXml column to NULL in MailboxBase table for corresponding user.

    I have perform following steps:

    1-Run Below update

    SELECT ExchangeSyncStateXml,MailboxId,* FROM MailboxBase

    UPDATE MailboxBase
    SET ExchangeSyncStateXml=NULL
    WHERE MailboxId='YourMailboxId' 

    2- Open specific user mailbox and run "Test and Enabled Mailbox" option which created new clientid and associated data
