All Exchange services and IIS are running with no errors in event viewer; information stores mount fine; users can connect to their mailboxes with both OWA and Outlook. The problem, however, is that messages received over the past two to three days are inaccessible and users are unable to open the message. It appears in their inbox and the subject is readable but attempts to open are futile. Within Outlook, there is no error message at all; using OWA users are simply presented with a 500 Internal Server Error page.
Messages that were already inside the inbox (and other folders) open fine (with both Outlook and OWA) provided they were received prior to the 2-3 day window mentioned above
Users are receiving email from both inside and outside the org; they can compose and send new mail successfuly both internally and externally; but again, new mail received cannot be opened.
I've tried everything I know; I've searched everywhere and if the answer exists then my tired eyes have simply overlooked it by mistake.
I am assigning a high point value as my client, while not losing email exactly, still is having issues responding to his customers...
One other point - Attempting to move or delete the unaccessible message results in a permission error...
Permissions on what exactly?
Thanks to anyone able to assist!!
