I have a user (my manager) who has read receipts set on their messages in Outlook. She is running Windows 7 and Office 2007. All works normally. Except on Sundays when I have our server setup to delete old message in everyone's deleted items folder that is more than 30 days old. This is setup through Managed Default Folders. When this happens, she gets multiple instances of "not-read" receipts for each message (three instances I believe). I have also confirmed that this is happening to other users as well, they had just been ignoring them and deleting them Monday mornings. They each have the same time/date stamp, same user, and same subject. This happens on a weekly basis.
I tested having her send me a message and manually deleting it out of deleted items, and she gets no response at all.
I had read somewhere that this was a known issue with Exchange 2010, and that it would be fixed in the next version. However, I have only found that on one site, and it was not a MS site. Can anyone shed some light on this? Either giving me a good work around (outside of turning off the read receipts) or confirming that this is a known issue? I appreciate any help. Thanks,
