In the last 2 weeks, 2 out of 3 people at my company are having issues uploading attachments to their e-mails, as well as having problems with sending e-mails out using Outlook Web Access.
Whenever they try to upload attachments or send out e-mails through OWA they receive the error "Microsoft Exchange issued an unexpected response (12031).
They are also sometimes receiving this error when logging into OWA.
They have no problems receiving inbound e-mails on OWA.
They have no issues with uploading attachments, receiving e-mail, or sending out e-mails using Outlook 2007.
Any help would be greatly appreciated.
Thank you very much for your time.
