Me: I need my OneDrive quota increased from 5 to 25 TB Support: Please reply with a screenshot of the problem, and any troubleshooting steps Each line is an action or an email: Me: fills out form explicitly stating that I have hit 90% and need quota increased from 5 TB to 25 TB I’ll spare you the back and forth email exchange, but a little snippet of the conversation went something like the following.

Increasing storage limit to 25 TBīefore you can set the limit any higher, you must first fill the OneDrive to 90% of its capacity, or 4.5 TB. If it’s set any higher, it won’t be saved. It should be noted that the maximum value that you can set as a default is 5120 (5TB). See Set the default storage space for OneDrive users for details. The default value for the tenant itself can be changed as well, so that this first step isn’t necessary for new users. The number 5,242,880 (5 TB) used for the storage quota must be precise. Set-SPOSite -Identity -StorageQuota 5242880 To increase a user’s OneDrive limit from the default of 1 TB to 5TB, it is a simple matter of running a PowerShell command, as documented in Change a specific user’s OneDrive storage space. It likely goes without saying, but all of the operations below require tenant admin permissions. I have just completed step 4, so that’s as far as this post will go.
OneDrive for Business offers “unlimited” storage. Note – – This article is still totally valid, but check the comment section below for an alternate method for getting your tenant enabled for > 5 TB storage.
