Hi, We have an Exchange 2010 server for about 5 months now. Recently a user (the CEO) with Outlook 2007 started receiving numerous "Not Read" messages of meetings that were set months ago, in bursts of messages, always at the same time, approximately 1 at night. All mails are forwarded to a Gmail account. We disabled the forwarding but still kept getting the Not Read messages. A delegate exits for that mailbox. All Outlook settings seem fine. This issue has been going on for a week and a half and has turned into quite a nuisance. Googled the issue but nothing relevant came up. Any suggestions? Thanks, Ben

Is that what time the Messaging Records Management is set to run? Are you deleting e-mail with MRM? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

No "Read Receipts" are set on the invitations. No Messaging Records Management is set to run on any mailbox. We don't delete anything with MRM.

Hi, Messages come from a Gmail account? Just forward? Or duplicated with the other messages? Please check the message id of those messages. Please check the organizer of those meetings. Regards, Xiu

Hi, Did some more running around and managed to get some more information from other users: Several users (including the CEO) have one delegate. That one delegate sets meetings for the users. None of the users stay up till 1:12 AM to delete meetings from 4 months ago, and certainly not in groups. What's going on at 1:12 AM? And why meetings from 4 months ago? @Xiu : Other users don't have forwarding to gmail or the sort, so i don't think it has to do with the forwarding. Thanks, Ben

I have seen this as well. I think its a bug. Hopefully SP1 will fix?

Hi, I came across a tab in mailbox properties and am testing right now. In the exchange 2010 properties of the mailbox, there is a tab "Calendar Settings" Under "Automate processing:" I unchecked "Enable the Calendar Attendant" for all relevant users. I will update in a few days and let you know if i still get the "Not Read" messages.

Hi, I checked the thread, didn't find anything helpful or anything i haven't tried Thanks, Ben

Other then asking your users not to send read receipts? There is no fix right now as far as I know.

It's been a week since I unchecked the Calendar Attendant and I haven't seen the "Not Read" messages since!!! Thanks

It's been a week since I unchecked the Calendar Attendant and I haven't seen the "Not Read" messages since!!! Thanks Note that disabling the Attendant means some things will not be enabled for that mailbox: http://technet.microsoft.com/en-us/library/bb124255.aspx Enable the Calendar attendant Select this check box to enable the Calendar Attendant or clear the check box to disable it. It is enabled by default. When Calendar Attendant is enabled, the following settings are made available: Remove meeting forward notifications to the Deleted Items folder If you select this check box, meeting forwarding notifications are moved to the Deleted Items folder after they are processed by the Calendar Attendant. This setting is disabled by default. Remove old meeting requests and responses If you select this check box, the Calendar Attendant removes old and redundant updates and responses. This setting is enabled by default. Mark new meeting requests as Tentative If you select this check box, incoming meeting requests are marked as "Tentative" on the calendar. If you don't select this check box, pending requests are marked as "Free". This setting is enabled by default. Process meeting requests and responses originating outside the Exchange organization If you select this check box, the Calendar Attendant will process meeting requests that originate outside the Exchange organization. This setting is disabled by default.
