3rd Party App Support

As a courtesy, provides information about how to set up certain third-party products, but we do not endorse or directly support any third-party products and we are not responsible for the functions or reliability of such products. can only provide support for the mail delivery up through the EDN provided Webmail Client, as that is all processed within the EDN Network. Use of Third Party Product (for example Outlook, Thunderbird, ect) is reliant on a number of external factors which are not controlled by EDN, and outside of the score of support. Mail delivery to Third Part Products is dependent on, but not limited to:

Local Processes
  • Amount of RAM
  • CPU Speed
  • Number of Processes running on computer
    • Browser Tabs open
    • Other Applications open
    • Types of applications open
    • Processes running in the background
  • Anti-virus applications running
  • Hard Drive Speed
  • Fragmentation of Hard Drive
  • Fragmentation of .ost file
  • Size of .ost file
  • Corruption within Applications
  • Corruption within System files
  • Processing order of operations
  • Maleware on computer
  • Virus on computer
  • Security Settings
  • Conflicting 3rd Party Add-ons
  • Number of devices connecting at the same time
  • Number of user in the case of a shared mailbox
  • Speed of Internet
  • Type of connection (Wired will be faster than WiFi)
  • Wifi strength
  • Distance from Router
  • Other Applications running
  • Number of people connecting to access point
  • Speed of firewall
  • ISP speed of DNS queries
  • Downstream ISP carrier speed/congestion
  • Possible Data Rate Limits
  • Time of Day (data speeds for an ISP will be much lower during peak usage times versus the middle of the night)
  • Distance to server (a connection from California will be much faster than say New York as the data has less distance and fewer carriers to pass through
  • Number of connections being made
  • Amount of data being processed
  • Number of messages queued

It is highly recommended to follow Best Practices for Data Usage. An email account/client is not meant to be used as a file repository. The more data in an account, the longer it is going to take to process.

By design, the IMAP protocol will do a periodic sync to the mail servers from the Email Client. This is to make sure the mail in the 3rd party client matches that which is on the mail server, every message received through IMAP has a unique identifier in the message which the email client uses to sync with the server.

This means that every time your email client performs a sync, it will process and sync *EVERY SINGLE* message. Each individual message is going to take some time, the more data there is, the longer it is going to take.

For example, if it takes 1/100th of a second for the data to go from your email client, to the server. It needs to do that for every single message when it is doing a sync.

Additionally, as the size of a message grows so does the time to process. It is recommended you do not store messages with large attachments (10Mb+) in your mail account as this will affect performance. It is recommended to save the attachment locally to a folder on your machine, or alternatively utilize a cloud storage solution. If your EDN account package includes One_Storage in the webmail, larger files can be stored there, depending on the amount of One_Storage you have. As the size of the data increases, so will the times it takes to process, as well as the likelihood of receiving sync errors. If the process takes too long, the email client will time out and the sync will fail.
