Open-Xchange PRO Review — Ingrain Jan 27, 2022 — The only issue I have when using Open-Xchange, has something to do with the file names in Open-Xchange. When the document is saved in Open-Xchange, its name usually does not end with the same name as the document file. For example, if you are saving a document in Open-Xchange, and you save that document as “A2A2A.pdf”, you would end up with the file name “A2A2A.pdf.psd”. Not exactly the best, but still... Cons: Some PDF documents open in IE, but that's no big deal.
