Attach documents to email OWA 2013 from a Shared network folder

Posted on 2014-10-28
Last Modified: 2014-10-30

I'm trying to figure out a way to increase the speed of uploading documents as an attachment from a shared folder to an email produced in OWA 2013.  At the moment I'm able to upload files that are smaller that 2MB's, but anything higher than that it takes forever to upload.

The file server and OWA 2013 are being used on the same network.  Does anyone have a direction I can take to increase performance?  The other option to use is to create a link to the file instead of uploading the documents as an attachment in the email.  The only problem with that suggestion is what if the users need to upload the file to an external source.  It would work great internally.

Are you accessing OWA remotely (not in the office on the same network as OWA)?  How do you access the file share?  Are you on a VPN?  Lots of questions, I know, but understanding how you're connected is key to being able to help with this question.  The fact that Exchange and the File Server may be on the same network, in this case, is irrelevant - it's what network that you're on that matters.

I'm wondering if you might be remote.  When you use OWA you're just on a website, be it one that's on your intranet or on the internet.    If you're attaching a file via OWA, that file first has to download to your machine and then upload to the Exchange server.  So, if you're on a slow link to the file server and/or the Exchange server, it'll be, well, slow.  

Hope this gives you a nudge in the right direction. I'll be watching for your reply.

Hello Thank you for responding.

OWA is being used remotely from different sites.  OWA is published using Citrix XenApp.  Users are trying to attach documents that are on a shared drive and attaching it to an email via OWA.  I'm trying to find a better solution to speed up the process.

Alright, so (while I don't know much about XenApp) with OWA being at a different site, I'm betting the speed problem is caused by the file needing to be uploaded from the users' computers to the owa server.

Things to consider / test:
1) The speed of the OWA server and network speed (download speed).
2) The speed of the network at each location - upload speed. is a pretty good estimate.
3) See if sending a file to a service like dropbox (using the web application, not the desktop application) is also slow.

Thanks again for the response.  I will test the speed, but I think its a mute point because its definitely uploading the docs from the server to OWA and it takes a long time to complete.  Since everyone is on the same network I was looking at just using a hyperlink to the file on the server to email, but I was informed that they will sometimes need to send the PDF documents to an external source.  I'm still looking for a better alternative.

Not really a moot point.  If speed of the network is good and the download speed of the owa server (I don't know if you're an admin, but if you are, test), then it's something else.  If it's a slow network, there's not much you can do other than compressing the files first.
