May 12, 2016 Well I ended up just watching VMware's VCenter to monitor the CPU usage. I also have a VMWare alert set so if the CPU usage is high for a while I will know about it. Not the best answer but at least it gets me part of the way there. Jan 13, 2008 When running idle, it was consuming around 20-30% CPU. I know that Outlook is no small app but 20-30% CPU when idle, c'mon! Trying to figure out what was wrong, I made sure I downloaded all the performance patches and I applied Office SP1 but still experienced a high CPU usage.

- Jan 13, 2008 I was having some performance issues with Outlook 2007. When running idle, it was consuming around 20-30% CPU. I know that Outlook is no small app but 20-30% CPU when idle, c'mon! Trying to figure out what was wrong, I made sure I downloaded all the performance patches and I applied Office SP1 but still experienced a high CPU usage.

At the same time, Outlook 2011 will report high (40% and above) CPU usage.

Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.
Symptoms
After you upgrade to Microsoft Office 2013 or 2016, you experience one or more of the following symptoms:
- The computer uses more memory when you open multiple Microsoft Excel files, save Excel files, or make calculations in Excel workbooks.
- You can no longer open as many Excel workbooks in the same instance as you could before you upgraded to Excel.
- When you insert columns in an Excel workbook, you receive an error about available memory.
- When you are working with an Excel worksheet, you receive the following error message:
Cause
Although improvements in Office 2013/2016 did not significantly affect system requirements, Office 2013/2016 does use more available system resources than Office 2010 did. The limit of virtual address space for 32-bit editions of Windows-based applications is 2 gigabytes (GB). For Excel, this space is shared by the Excel application itself together with any add-ins that run in the same process. The size of the worksheet itself also affects the usage of virtual address space. Because Excel loads the worksheet into addressable memory, some worksheets that have a file size of less than 2 GB may still require Excel to use more than 2 GB of addressable memory. This situation results in the error message that is mentioned in the 'Symptoms' section.
Resolution
Excel expert users who work with complex Excel worksheets can benefit from using the 64-bit edition of Office 2013/2016. This is because the 64-bit edition of Office does not impose hard limits on file size. Instead, workbook size is limited only by available memory and system resources. On the other hand, the 32-bit edition of Office is limited to 2 GB of virtual address space, and this space is shared by Excel, the workbook, and add-ins that run in the same process. (Worksheets smaller than 2 GB on disk might still contain enough data to occupy 2 GB or more of addressable memory.)
The following options can help improve performance in Excel 2013/2016:
- Excel users who regularly work with large, complex Excel worksheets may benefit from using the 64-bit edition of Office 2013 because 64-bit editions of Windows-based applications can address up to 8 terabytes (TB) of memory. Learn more about 64-bit editions of Office 2013.
- The 2-GB limitation is per windows process instance of Excel. You can run multiple files in one instance. However, if the files are really large and have to be open, consider opening multiple instances for the other files. For information about limits that you may encounter, see You cannot paste any attributes into a workbook in another instance of Excel.
- If you are running Windows 7 or Windows 2008, we suggest that you install Platform update for Windows 7 SP1 and Windows Server 2008 R2 SP1.
- Test performance without COM add-ins. COM add-ins can use memory at the expense of the 2-GB limitation. For testing, disable COM add-ins, and then start Excel. If COM add-ins are causing the memory issue, contact your third-party vendor for an updated copy or a 64-bit version of the COM add-ins.
- Disable hardware graphics acceleration. This shuts off animations. To do this, on the File menu, click Options, click Advanced, click Display, and then select Disable hardware graphics acceleration.
- Change your workbook to streamline areas that use memory unnecessarily. For suggested changes, seeHow to clean up an Excel 2013 workbook so that it uses less memory.
