This issue can be caused by a few issues, the following are:
Printer Queue on the Access UK Ltd. PDF Printer having an Error or being Stuck
A Recent Windows Update has affected this part of the system
The Users Email is not set up correctly
There is an issue with the SMTP Queue which your IT will need to look into and make sure it is okay (They should know how to check this as it is outside Supports Remit to look into the SMTP Server)
To fix the issue with the Printer Queue on the Access UK Ltd. PDF Printer.
Search for Printers and Scanners (windows 10) in the Windows Start Menu
Click Open Queue on the Access UK Ltd. PDF Printer
If this is full Scroll to the Bottom of the Queue and see if there is a Document with an error
If there is no Error please look into the other possible causes of this issue.
If there is an Error with this queue click Printer at the top of the Queue pop out and click Cancel all Documents. This should clear them. If this does not Clear the queue then proceed with the next steps:
Go to Start, Control Panel and Administrative Tools.
Double-click the Services icon.
Scroll down to the Print Spooler service and right-click on it and select Stop. In order to do this, you need to be logged in as Administrator.
Note: If you cannot do the above due to Administrator Rights, please pass this onto your IT.
At this point, no one will be able to print anything on any of the printers that are being hosted on this server.Next you need to go to the following directory: C:\WINDOWS\System32\spool\PRINTERS. You can also type %windir%\System32\spool\PRINTERS into the address bar in Explorer if the C drive is not the default Windows partition. Delete all the files in this folder.
Now you can go back to the Services console and right-click and choose Start for the Print Spooler service.
To resolve a Windows Update causing issues:
The best way to fix this is to Uninstall the latest Windows Update and see if this fixes the issue.
It is often an issue where a Windows Update comes out and it causes issues with Printing/Emailing Remittances. This is an unavoidable issue as we cannot always build around new updates. It is best to just revert back until a newer update comes out.
The Users Email is not set up correct, using MAPI:
In Dimensions, click System
Click into User Records
Select the affected User
Click Edit from the Ribbon
Click E-Mail from the Ribbon
Fill in the Profile Name, Password and E-mail
The Users Email is not set up correct, not using MAPI:
In User Records
Click Options from the Ribbon
Click Edit
Click the box located under E-mail Setup:
Change this to SMTP
If this does not work, ask all users to log out then reboot the Remote Desktop. If there are any further issues with email it would be best to speak with your IT first to ensure there is nothing wrong with any SMTP Servers if you are using these.
