Project Online: software boundaries and limits

Project Online: software boundaries and limits

< More Project help

There are some important limitations that you should know if you are using Project Online. These limitations apply regardless of whether you are using Project Online by itself, or with other Office 365 plans.

Tip: Want more info about Project Online and Office 365 plans?    Take a look at the service descriptions for Project Online and Office 365.

Limits in Project Online

To keep Project Online performing at its best, there are some limits to how much data you can realistically store:

For reporting, there are also limits to how many single-value custom fields, of each type, get stored in the reporting schema.

Project custom fields

Timesheet custom fields

Task and Resource custom fields, combined

450 text fields

450 text fields

450 text fields

450 lookup tables

450 lookup tables

450 lookup tables

450 of all other custom field types (cost, date, duration, number, flag)

450 of all other custom field types (cost, date, duration, number, flag)

450 of all other custom field types (cost, date, duration, number, flag)

Note: While you can create more custom fields than these limits, only this many custom fields will be included in the OData feed. You are not able to choose which of the fields are included.

Also for reporting, if an individual report's source Excel file is larger than 10MB, it cannot be refreshed in Excel Online. Instead, you can:

  • Refresh the report using Excel 2013.

  • Purchase Power BI for Office 365 to extend that 10MB limit and refresh the report in Excel Online.

Other considerations

Beyond the data and custom field limits, there are a couple of other variables to consider.

Changing domains is not supported

If you want to use your own domain, like contoso.com, instead of the default domain, like contoso.onmicrosoft.com, you need to set up your domain before adding users to Project Online. Changing domains after you've added users is not supported.

It takes more time to load more projects

Because it takes more time to load more projects, someone who has access to a lot of projects may find it takes longer to do some things, like opening the Project Center or changing views in the Resource Center. Consider setting up filters to cut down on the load time for those users who have access to a large amount of information.

It takes more time to calculate multiple calendars

When a project, task, or resource has its own custom calendar, Project Online takes a little longer to calculate the dates for the work going on in your organization. Consider whether it makes sense to make some of the calendar changes on a broader scale, across your entire organization.

Your connection speed matters

If your connection to Project Online is running slowly, it can take a little longer to do things like load reports with a lot of data, or open, save, and publish a project through the Project Online Desktop Client.
