We recently received a report that Customization policies were failing to save when new or updated. Upon investigation, we discovered that a recent change caused generic error to be displayed when you upload a branding logo larger than 400 x 400px.


If you run into this, you’ll see the following error:

Customization policy errorCustomization policy error

To work around this, reduce the file size of your logo.


In an upcoming release, we’ll remove the 400 x 400 px maximum requirement and only the 750KB maximum will remain.  Note, there is no end user impact.


Let us know if you have any additional questions on this topic by replying to this post or reaching out to @IntuneSuppTeam  on Twitter.
