What happens if you save the attachment to a local store BEFORE attempting to edit. Files opened from Outlook store in a TEMP directory and that directory should not be used for long term storage.


Are you attempting to save the modified file locally or to a network drive.

Hi Julie
When I attempt to use the save as feature on the .mpp file opened directly from the Outlook email attachment, I do use a local folder, not the temporary directory. So I don't understand why I am getting the error.

If I attempt to save the .mpp email attachment to a local folder before editing, and then open the locally saved file, it works fine. I can edit the locally saved file and re-save. However, that is no use if you have just spent an hour updating a file opened directly from Outlook and then cannot save the changes.

So yes, there is a workaround. But that doesn't actually resolve the problem.

Thanks

The problem recurred yesterday on another person's machine. She had opened the file directly from her allocated space on the network. She attempted to "save as" and received the same error. There was no email attachment involved in this instance. She could "save" successfully but not "save as".

The issue with the coworker sounds more like a network latency issue than a Project issue. It is possible your issue is also the same.

What OS are you using? Which version of Project and what service pack level?

Hi Julie
Thanks for the update. I am using Windows XP Professional, with MS Project Professional 2010 version 14.0.7116.5000 (32 bit). I don't know how to determine what service pack is installed.

Can you explain to me (as a non-technical user) how a network latency issue would cause "save as" to fail but not "save"?

Thanks

You can check what service pack is applied in Project 2010 through:

File > Help.
On the right side click the link Additional Version and copyright information
At the top of that dialog you should see:
SP2

Regarding the difference between Save and Save As. A Save is incremental adding only what has been added to changed to the file. A Save As is a completely new file, calling on the network to create a completely new file and using more resources.

Thanks for the reply Julie.
Now that I can see where the service pack is identified, I can see that I only have service pack 1. I have asked our IT department to rectify that. The possible network latency issue is probably going to be harder for them to confirm/fix.

Great. Have the latest SP applied. The unscientific method of checking network performance is to work on the file locally (your laptop) and then move them to a network drive after the work is done. See if that solves the issue.
