Cannot Add Attachments Using the SmarterMail Web Interface

Sometimes end users may be unable to attach files to emails they send through the webmail interface. This can be resolved in a few short steps. 

Applies to SmarterMail 8.x - 15.x

First, verify that the permissions on the MailProcessing folder are set correctly. To verify the permissions, do the following:

1. Log in to SmarterMail as the system administrator.
2. Click the Settings icon.
3. Expand the Activation folder.
4. Click SmarterMail Self Diagnostic.
5. A new window will open and display folder permissions. It will also indicate if they passed or failed.

If any of the permission tests fail, you can fix it by doing the following:

1. Using the Windows Explorer, right-click the default folder C:\Program Files\SmarterTools\SmarterMail\MRS\Mailprocessing directory.
2. Select Properties and then click the Security tab.
3. Select Network Service and make sure that Modify is checked and then click Apply and OK.
4. Repeat the process for the Config directory.
5. Log in to SmarterMail as the system administrator.
6. Click the Settings icon.
7. Expand the Activation folder.
8. Click SmarterMail Self Diagnostic.
9. A new window will open and display folder permissions. It will also indicate if they passed or failed.

Another possible cause for this problem is that disk quotas have enabled on the Network Services Account and it has reached its limit. If so, disable disk quotas on this account and then once this is done rerun the SmarterMail Self Diagnostic to check if the permissions test passes.
