# Edit Microsoft Office documents
# Check out to OneDrive
Use this function to check out a Microsoft Office document in ELO to Microsoft OneDrive for editing. The document is stored in your OneDrive folder until you check it back into ELO.
This function is only available if you have a Microsoft school or work account with Microsoft OneDrive for Business that has been activated for ELO by an administrator.
Please note
You can only use this function to edit documents with standard file formats such as DOCX. The document size is limited to 4 MB.
For documents with older file formats like DOC, use the Check out and edit function.

Please note
You cannot check the document back into ELO until all users who are editing the document have closed it.

Please note
You may not be able to check a document in if you are editing it in the Firefox browser and use the uBlock Origin ad blocker extension. In this case, disable the extension or switch it off for the relevant page.
