Hi guys, I've set up calendar and task content synchronisation between Sage SalesLogix clients and their Outlook 2010 mailboxes hostend on Exchange 2010 SP2 through Sage Exchange Link v8. I ran a test sync for 10 users and everything seemed to be working, but the CAS server logged several errors "MSExchange Common 4999". There were no complaints about Outlook or Exchange accessibility or performance, but I turned the synching off as I wasn't sure about this. I'm still waiting for Sage to come back to me about this, and I wonder if anyone of you have seen this before. I've found that a similar issue was reported some time ago, but the details were a bit different, and I'm on SP2 now. exchange common event id 4999 New-MailboxImportRequest isn't finishing. Can't work out why.
