General instructions for recovery of Mail to Fax function
As a result of failed experiments with various types of email attachments you may encounter situations when the e-mails are no longer accepted by Fax Voip T.38 Modem and the Mail to Fax function does not work (it is assumed that all POP3 / IMAP Settings are correct). When this happens, an increased CPU usage may be displayed.
Examine the Mail to Fax log - Microsoft Fax
1. Follow the instructions in the To view Mail to Fax log - Microsoft Fax chapter to enable logging.
2. In the Fax Voip T.38 Modem Control Panel, click <STOP> and then <START> to restart Mail to Fax subsystem (Fax Voip T.38 Modem MsFax Mail service).
3. Wait at least 5 minutes. The internal timeout of FaxDocument.ConnectedSubmit and FaxDocument.ConnectedSubmit2 methods (Fax Service API) is 5 minutes and this can not be easily fixed in our application. 'The wait operation timed out' may be returned after 5 minutes of waiting, during which the Mail to Fax subsystem hangs. This will be reflected in the log file and you will be able to fix the problem by blocking the bad file extension which caused an error, see in the E-mail attachments (Microsoft Fax) chapter of this user manual.
4. Click Options in TreeView, then click E-mail Logs. To view the log, click <View> button near the Enable Mail to Fax and Outgoing Routing Methods debug logging - Microsoft Fax checkbox.
5. Examine the log file and try to fix the problem. You can also send the log file to our support team by e-mail.
