When you open an email attachment (for a Microsoft Office application) in Microsoft Outlook 2010, the attachment always opens in Read-Only mode. The following figures demonstrate this behavior with Microsoft Excel and Microsoft Word attachment.
Note This behavior is a bit different with Text files. You can open the .txt file attachment and the window will not say "Read-Only". However, if you try to save the file, you will be unable to save the file back to the message. Instead, the Save As dialog box will appear.
To open an attachment in Outlook 2010 so that it is not read-only, please follow these steps:
- Open the email message that has the attachment.
- On the Actions control in the Ribbon, click Edit Message. (The screen shot for this step is listed below).
- Open the attachment.
