If you’ve over used a trial install of Office you’ll find that it goes into a limited usage mode – basically making it so documents are read only and not editable.
If you haven’t yet got a licence or don’t have access to it – you can reset the trial period up to three times.
The steps below show how to reset the trial period for Office 2016. It is a similar process for Office 2013 and Office 365.
Nov 27, 2018 Manually running OSPPREARM.EXE seems to work fine, at least it gives the rearm successful. Here is a screen from the BDD.log of the error: Wednesday, November 28, 2018 7:38 PM.

Like in earlier Office versions, when installing Office 2019/2016 or Office 365, a user is offered to try the product for free during 30 days. In 30 days trial some of the Office features are blocked, and a user is prompted to purchase a license and activate the product (using a retail/MAK key or a KMS activation), or to uninstall Office completely. However, there is a little trick that allows you to extend your Microsoft Office free trial period up to 180 days.
The MS Office package (both the classic MSI package of Office 2016/2013/2010 and the Click2Run distribution of Office 2019/Office 365) includes a special tool, ospprearm.exe, which is located in the directory:
- On 64-bit Windows versions with 32-bit Office version installed —
%SystemDrive%Program Files (x86)Microsoft OfficeOffice16
- In other cases —
%SystemDrive%Program FilesMicrosoft OfficeOffice16
%SystemDrive%Program Files (x86)Common FilesMicrosoft sharedOfficeSoftwareProtectionPlatform
Or
%SystemDrive%Common FilesMicrosoft sharedOfficeSoftwareProtectionPlatform
In any case, you can try to find the location of the ospprearm.exe file manually.
Open the command prompt as an administrator, and run the following command to change the directory:
To extend your trial version of Office for 30 days, run this command:
cd %SystemDrive%Program Files (x86)Microsoft OfficeOffice16
To extend your trial version of Office for 30 days, run this command:
OSPPREARM.EXE
The following message will appear:
Please note that this license rearm method is only suitable for corporate versions of Office and Office 365 (Office 2016 vs Office 365: What’s the difference) licensed under the Volume Licensing (Standard, ProPlus and Enterprise editions). Accordingly, you won’t be able to reset the free trial time in retail editions (Home, Personal, University, etc.).
Thus, you rearm your Office 2016/365 copy and extend free trial to 30 days. You can run this command up to five (5) times on every 30 days of trial. Thus, you can extend the total time of using the Office 2016 trial version up to 180 days (6 * 30 days). You can check the current activation status and the number of days left for the grace period to end as follows.
cd %SystemDrive%Program Files (x86)Microsoft OfficeOffice16
cscript ospp.vbs /dstatus
In this example, you can see that you have installed a trial version of Microsoft Office 2016 and there are 4 days left before the trial period ends.
When running the ospprearm.exe command:
- The trial period counter for Office resets to 30 days. The activation timer is frozen until the first launch of any of the Office apps;
- The computer CMID is reset (the KMS server determines unique clients according to this CMID. You can check the current CMID of the computer using the vbs script – see the KMS activation FAQ).
Tip. This opportunity to extend the Office trial period is described on Microsoft website. However, it may be considered a violation of the license agreement. So you postpone the activation at your own risk. You can rearm your Office 2010/2013 trial in the same way.
Resetting a trial Office license using ospprearm.exe is useful if you are preparing a Windows reference image with Office preinstalled to deploy on a users’ computers via WDS, SCCM, or to manually install the image. Before capturing a reference Windows image, you need to reset the activation counter with the ospprearm command (and do not start Office apps until the image is captured). In this case, after deploying the Windows image on the user’s computer and after the first launch of any Office application, you can use Office without activation and restrictions for a full 30 days.
