Enterprise Calendar - Preview 2016 RRS feed

  • Question

  • We use Project Online with Project Professional Pro 2013 and am now unable to edit the enterprise calendar.

    When I try to edit or create an enterprise calendar from PWA | Enterprise Calendars (Usine IE 11), it errors with 'Project cannot open the file.' twice then after a delay another message pops up that says 'You need to have Microsoft Project Professional 2016 Preview installed and configured to connect to a profile for this Project Web App site.'

    In PWA | Additional Server Settings,  I have allowed Project versions '15.0.4128.1014' and above.  My Project Professional Version is '15.0.4569.1504'.

    I seem to be capable of saving project files to the project online server fine, though.

    Please help.

  • Hello,

    This is an issue already raised at Microsoft support level, wait and see.

    On the meantime it seems you can test to disable Protected Mode for the Internet-level security setting and then restart IE. Seems it worked for someone on MS support, but not for me.

  • I saw this a while ago.  Are you using MS Project to log into multiple tenants?

  • Hello,

    Got infos from MVP's distribution list, can you try this workaround while MS is working on a solution:

    1)      Say the Project Server instance I need is
    2)      Boot Project
    3)      File -> Info -> Manage Accounts -> Add -> name = My Computing, url =
    4)      Ok
    5)      OK
    6)      Close Project
    7)      Boot Project connected to that new account
    8)      Boot IE
    9)      Navigate to
    10)   Gear -> PWA Settings
    11)   Enterprise Calendars
    12)   Select a calendar
    13)   Click Edit
    14)   Microsoft Project is activated and shows the UI for editing the calendar

  • Hello,

    I am having the same issue.  I have my pwa URL set as my default account in MS Project 2016.  I also use my default pwa url when starting MS Project 2016.  My Project Web App Account in MS Project is linked to Project Online.  I log out and log back in.

    I then go into my PWA site, click tools, and Enterprise Calendars.

    Then select Standard and click edit.  I still get the same error "...Microsoft Project Professional 2016 installed and configured to connect to a profile for this Project Web App site...."

    I am using O365, Project Online 2013 and MS Project 2016.

    Any help would be greatly appreciated as I can't properly measure resource allocation if I don't know what days they are/are not working :).

  • I tried this today on a tenant where I could not edit the enterprise calendar.  I connected and opened MS Project and then initiated used Internet Explorer (not Edge) to initiate editing the calendar.  Using Chrome didn't work.

  • Thank you!  I am using IE Explorer, IE 11.  I am not using Edge (although it is installed on computer. I did read that security settings, even in IE Explorer may have an impact.  If this is true, I am not sure what settings need to be adjusted (I may have to ask for specific permissions to adjust to certain levels). 

    Any thoughts on this?

    Thank you!
