Mail server setup
Be aware that some mail servers have limits on the number of emails that can be sent at the same time or within a time interval. This can primarily be a challenge for mass updates.
Error messages
Below you can read about some of the error messages you may encounter when sending e-mail from Uniconta. All the messages originate from the email setup you have and are often an error from the provider of the email you have created in Uniconta.
If you get any of these errors, or others not listed below, search the web for the error you are getting.
Microsoft Graph (Application is over its IncomingBytes limit.)
A maximum of 150 MB (the size of all email attachments) can be uploaded per 5 minutes.

If you get the error below, contact your Office 365 administrator.
"The smtp server requires a secure connection or the client was not authenticated 5.7.57"
"Client was not authenticated to send anonymous mail during mail from"
It is about setting up authentication for others to send on behalf of the set up email.

5.7.1
The server response was: 5.7.1 unable to relay
Check "Default SMTP Virtual Server"
Use IIS7 to deploy your web site, Open IIS6 Manager to configure SMTP server (why?).
Configure SMTP server as follows:
- Open IIS6 Manager using Control Panel --> Administrative Tools.
- Open SMTP Virtual Server properties.
- On General tab, Set IP address of the Web server instead of "All Unassigned".
- In Access tab, click on Relay button, this will open Relay Restrictions dialog.
- In relay computers list, add the loopback IP address i.e 127.0.0.0.1 and IP address of the Web server, so that they can pass/relay emails through the SMTP server.
535: 5.7.139
The most common reason that you are receiving this error is that the application or device trying to send the email is using SMTP basic authentication. As of October 1st 2022, Microsoft automatically disabled SMTP based authentication in Exchange Online. This means that any existing uses of SMTP will stop working. Luckily for some, you can re-enable SMTP based authentication, but until the end of December, however it is deemed very insecure and you should look to remove it in your environment asap.
How to fix this
Remove the need for SMTP email submission
Re-enable SMTP email submission while you work on removing the need for it
