  • 1. Is there a way I can use e-mail to create tasks in Project?
    I'm wondering whether there is a e-mail submission method to create tasks in Project, similar to bug submission method in Bugzilla.

    Saving a baseline I just want to confirm something. If I baseline an entire plan and track progress for a week, then add a few new task items. When I save the baseline again, I only save the selected task (the new ones) using the option in to only save the selected task, this will not re-set the baseline for the entire project tight? It will only add the new selected task to the existing baseline right?

  • 5. Start date in "task usage"
    I have a problem with View/Task Usage. Everytime I open my project, the timewindows start months ago... How can I set which date should be the start date, when displaying "task usage". I have tried to set "status date", and used "project update" to move all unscheduled work to a far later date. This problem means I have to scroll the timebar approx. 4 month after every start of project, to get to the place where I can enter work. I have loaded SP1 with no change

What is the purpose of the question make in the Duration column and ho
do you make it disappear? 

I'm new to Project (an old hand at Access) so apologize for what i
probably a very rookie question. 

Sorry, I seem to have posted this question twice.  At least I admitte
to being a rookie.

Hi cassidym,

Welcome to this Microsoft Project newsgroup :)

The question mark indicates that the duration is tentative or estimated.
When you actually type in a figure for the duration, the question mark will
disappear.  Tools/Options.../Schedule tab has an option to switch this off.
However, it seems to me to be a very unnecessary facility as, after all,
aren't all the durations estimates?  If you leave the question marks there,
you can filter for uncertain durations to allow you to firm up the ones
you've missed.

As a beginner, you might like to have a look at my series on Microsoft 
Project in the TechTrax ezine at this site:  http://www.**--****.com/ 
(Perhaps you'd care to rate the articles before leaving the site, :) 

Hope this helps - please let us know how you get on :)

In article < XXXX@XXXXX.COM >,

The question mark simply indicates that the duration is a best guess 
estimate. You can remove it under Tools/Options/Schedule. Uncheck the 
option to "show that tasks have estimated durations".

Incidentally, I forgot to mention that you can type in the duration with a 
question mark to bring it back again.

One more question. Somehow, I've locked my initial task so that it onl
shows it's duration as equal to the combined durations of the subtasks

When I try to extend the finish date of the primary task, I can't ge
the calendar to open. The only way I can extend the time frame is t
add another subtask or extend the last one.

Obviously, I've changed a setting that is enforcing this

Any ideas what I did and how I can rectify it

Hello cassidym,

I assume you are talking about the project summary task (line zero). 
You have done nothing incorrect.  Summary task durations are calculated 
by Project and are the span of working time from the start of the 
earliest subtask to the finish of the last subtask.  As you note, the 
only way to change the duration is to change the schedule of the 

I hope this helps.  Let us know how you get along.

1.Question mark in Task Duration

Can anyone help with this simple problem?

Why does the Duration box in the Task Form have a question mark after
the estimated duration?

Typically I enter new tasks in the Task Form. My default Task Type set
to Fixed Work. I assign a Resource and enter the Work in the fields
provided. If the resource is not fully available, I adjust the Units.
The Duration box then gives me an estimate of how long the task will
take to complete. Nice. For example a 1 day task assigned to a 20%
resourse will take 5d to complete. But Project displays "5d?"  I don't
understand why sometimes there is a ? after the duration estimate and
sometimes not. Any ideas? 


2.Red mark and blue mark in timesheet hrs


For some of the task hrs in timesheet, the hrs shows red and for some the 
hrs shows blue color.

I understood that for approved ones the hrs shows black color. But, what it 
indicates when the task hrs shows red and blue color.

Any thoughts on this would be greatly appreciated.

Thank you

4.? mark in Duration

I know this is a stupid question, but why do the ? marks show up in a 
duration? How can I get them to default to not showing up? How do I remove 
exisiting ones. I have just taken over a file from a client tha tis filled 
with them and Im on a time contraint.
I knowits some simple function that I am overlooking

5.What is the purpose of the question mark (?) in the duration field?

What is the purpose of the question mark (?) in the 
duration field? I know it is used to indicate an 
estimate.  Is that the only purpose - just an indicator?  
Does it server any other purpose or control how MS Project 
works in any way?
