Hello.
We use an Exchange 5.5 mail server. The problem we face is that suddently one day, I could not reply or forward to a mail message using Outlook Web Access. If I click the reply button then nothing happens.
I noticed that this problem affects only some of the mailboxes (not all).
Furthermore I found out that the OWA “out of office” notification option is not working for some mailboxes, too.
Also, there is a mailbox that whenever I try to access it in the Configuration->Servers->Private Information Store -> Mailbox resources, I get this error message: “An unexpected, unknown error has occured MAPI or an unspecified service provider ID no: 8004011b-0000-00000000”.
I can not delete this mailbox. If I try to delete it I get this error message:
“An internal processing error has occured. Try restarting the Microsoft Exchange Administrator program or the Microsoft Exchange Server computer or both. Microsoft Exchange Information Store ID no: c1040af4”
Any ideas what is going on and how can I repair all of these problems?
Thank you in advance.
