We have been having this issue for a few months.

Previously, users could navigate to Public Folders and open Excel or Word documents, make changes, save and close without issue.

When this problem first started, users were getting files open as Read Only. We were unsure why this was happening and could not find a fix, so we put out an instructional document on how to: disable Protected view in Excel or Word, turn off attachment previewing in Outlook and disable the preview pane. If users performed these steps, they could then operate without an issue.

Now it is occurring again, even with the above fixes in place. We tried setting up a Group Policy to make these settings and it didn't help.

My sysadmin had me block the following updates in WSUS: 2687567, 2965295 and 2956128. We thought this may be the cause but to no avail. On my work desktop and laptop it occurs with these updates not installed.

We can access the documents OK, without Read Only status using Outlook Web Access. We are using a mix of Windows 7 Professional and Enterprise. We are using Exchange 2008, Office 2010.

Thanks for any help you can provide.

Hi,

Based on my knowledge, since Outlook 2010, it seems to be by design.

The easiest way to open and modify the attachment in the message, is to "Edit" the message, then open the attachment, make changes in the attachment and save the attachment, then Save the Message.

You mentioned "Previously", was that a previous version of Outlook?
