Exchange 2007 - meeting requests going to drafts

Good Morning Experts,

I'm having a rather unusual issue in Exchange 2007, to do with meeting request.

Using OWA, so as to remove Outlook client as a cause, when a meeting is created within the calendar and an invitee is set (either internal or external, using either the GAL or typing manually), the email request goes into the sender's drafts folder within OWA.

Attempting to forward this request from drafts to the intended invitee results in the forwarded request going to drafts as well.

There are no transport rules set in Exchange.

We're getting the following erros in the app log at the same time:

EventID 1014:

The store driver failed to open the message item for event 17977163 mailbox 6920296b-122f-4218-b348-f55b0cd48436 MDB d03490fc-168f-4199-bb6e-71fb2c7c16f4. An NDR won't be generated.

Also Event ID 9554:

Unable to update Mailbox SD in the DS. Mailbox Guid: 74927dc6-6748-4960-8ce1-e1cc992e6a5d. Error Code 0x80070005

Any help appreciated!

Hi All,

It seems like Exchange needed some update rollout pack. Applying this and rebooting solved the issue, although I'm no closer to understanding exactly what caused this rather unusual behaviour

I'm having the same problem but in OWA and Outlook but only for one user.  What exactly was the update "rollout pack" that you found to be the solution?
