Opening emails in SharePoint

February 22, 2014 Leave a comment

As part of a recent project we used SharePoint to store emails, both via incoming emails and one of the 3rd party drag and drop tools.


Most users were happy with the solution once we had updated the MIME types to allow emails to be opened rather then downloaded, but some still mentioned they would rather that email opened directly from SharePoint rather than seeing the yellow download bar that Internet Explorer puts up.


A bit of digging around on the internet came up with the solution from this Microsoft KB article

To enable emails to be opened directly from SharePoint the trick is to disable the Internet Explorer download bar for email file types, to do this add the following registry key to your local machine.


then run the assoc command below to get your .msg file extension type (mine is for Office 2013)


Now add that file type as a zero length binary value to the key created above.


Emails will open directly from SharePoint.


Found an issue [WITH FIX] with SP2010 April 2012 CU : incoming emails not going to SharePoint

Issue :

Incoming emails to SharePoint are all configured properly and emails are being received in the server’s SMTP Drop folder but they stay there and are not picked up by SharePoint.

Troubleshooting :

Looking at ULS Logs the following error is showing :

E-mail cannot be delivered because site is over quota or locked for editing. Site URL: http://xxxx.

Researching :

A quick Google and it seem that CU April 2012 has raised this issue:

SharePoint incoming email Fix :

Following the steps fixes the issue except for Nintex:

-> SharePoint Central Administration > Application Management > Configure quotas and locks > on the Site Quota Information section >  set a limit (i.e: 5000 MB) on this setting:  “Limit site storage to a maximum of:”  > and then press “OK”.

Nintex issue :

I now work a lot with Nintex workflow and one of the greatest feature in the product is the ability to approve a task via email response called “Lazy Approval”.

The issue with the above is that Nintex drops the Lazy Approval emails in to a HIDDEN library under the Central Administration, therefore we need to set a quota to the Central Admin site as well but as you will experience there no way to select the Central Administration Web app when setting Quota.

Nintex Lazy Approval Fix :

I found the fix on the Nintex connect forum here.

1) get the storagemaximumlevel for Central Administration using PowerShell :

$ca = get-spsite -identity http://sharepointserver:portnumber

Result should be 00000 since no quota is usually set for Central Admin site.

2) set a maximum quota



No IISRESET is required and email will leave SMTP DROP Folder to be treated by Nintex Lazy Approval in a few seconds once Timer Job restarts.

Conclusion :

Seems that either not many environment use Incoming Emails to Sharepoint libraries or not many have upgraded to April 2010 CU since there isn’t much articles about this, hopefully the next CU will fix this issue otherwise make sure you include this workaround in your Sharepoint and Nintex configuration.


[Update] April 2012 CU was removed and re-releaed however it still does not fix the incoming email, making this look like a definite move to disable it by default.
