When you open an attachment right from the e-mail message, it is opened as a temporary file in Windows temporary directory and you only have read-rights on it. This is handled this way by Windows.

You can either open the attachment in Open Office as you used to do and save a copy of the edited document in another directory, so you can attach it to the message, or you have to save the attachment first and then open the saved document.

When accessing an OpenOffice document that is sent via email as a file attachment you are given two options; opening the file or saving the file.

If you choose to open the file directly with OpenOffice, the Operating System first saves the document to a temporary location (In Windows, C://Users/User Name/Appdata/Local/Temp) which causes it to be marked as read-only.

To ensure that you can edit the document, select the "Save File" option instead and then store the file on your computer before opening it with OpenOffice. Then it is not opening from a temp folder.

Alternatively: click on the Attachment and choose 'Detach' choose where to save eg: You have created a special folder in 'Documents' or 'Desktop' called 'TB Attachments', so you select that folder.

This removes the attachment so reducing the email size, but it puts a link in the email, so you now.... Either click on attachment in email and select 'Open' ...the created link will open the detached attachment document in 'TB Attachments' folder in 'Documents' in read/write mode. Or open the document directly from the 'TB Attachments' folder in 'Documents'
