I can't upload .zip file more than 100mb.

Good day,

ZXP plugin section allow to upload files upto 300mb but I can succesfully upload not more than 100mb files. When I trying to upload zip files more than 110mb - its starting upload process and stopped soon (1-2 minutes) without any notices or errors from Exchange.

I trying some browsers, shutdowning firewalls but it's not help.

Also I want to ask: Is it planned to increase file limit more than 300mb in future?
