Email Archive Configuration Mail Server Connection Failed

asked on September 22, 2020

User is trying to configure Laserfiche Email Archive but is unable to connect to the email server in the profile configuration.  The Test Connection button in the Mail Server section displays, “Connection Failed.”  The ports have been checked.  Wireshark indicates the Exchange server is refusing the connection.  The firewall is off on the Exchange server.  Both servers are on the same VLAN.  Tried both SMTP and IMAP configuration.

Exchange Server: Windows 2008 R2, Microsoft Exchange 2010

Exchange Server 2: Windows 2012 R2, Microsoft Exchange 2013

Laserfiche Server: Windows 2019 Standard, Laserfiche 10.4

Anyone have any suggestions of what to look at to allow the Laserfiche Email Archive to communicate to the Exchange server?

I noticed the config specifies the IMAP SSL port of 993 without having "Use SSL" checked. The non-SSL IMAP port is 143. It's possible you're getting a TLS handshake failure. Try checking "Use SSL" in Email Archive or changing the port to 143.

Also trying running these two PowerShell commands from the server Email Archive is on if you haven't already:

New-Object System.Net.Sockets.TcpClient 'ExchangeServerHost', 143

New-Object System.Net.Sockets.TcpClient 'ExchangeServerHost', 993

Replace 'ExchangeServerHost' with the actual hostname.
