MailCOPA has been tested in a variety of situations, but there will inevitably be software and/or hardware environments which might cause problems. In this event, Intervations will endeavour to resolve the situation. See the page on Technical Support.
The Database.
The database has been used and rigorously tested by Intervations in other applications, and has proved reliable and stable, as it has in this implementation. It is capable of holding huge quantities of messages, and accessing them quickly. There are a couple of possible issues.
Unseen Count
The count of unseen messsages against each folder might occasionally be wrong - the running count maintained may become corrupted. In the event that this happens, using the menu option Utilities 
Recount Unseen Messages will quickly rectify the problem - it will scan the database and recalculate the running count for each folder.
Reindex
In the event that you appear to have database-related problems, please contact MailCOPA support who will advise you. The specific keys and the order in which they should be reindexed varies depending upon the problem presented.
Windows Vista
Vista increased emphasis on security sets new challenges for programmers. We have been able to manage many of these but the following remain:
Default Mailer - Unlike previous Windows operating systems, it is not possible to programmatically set the default mailer (so that for example mail links in web pages will use MailCOPA rather than, say, Outlook Express. The settings here will be disabled under Vista.
To set MailCOPA as the default email application:
Go to the Windows Start Button at the bottom left of your screen.
Select Default Programs
Click Set your default programs
Select MailCOPA in the list of Programs
Click Set this program as the default
Click the OK button.
Messages with unusual formats.
These have been seen occasionally, and some of the problems cannot be resolved. They are due either to non-standard formats in the messages themselves, or the viewer's handling of them. You always have the option of selecting View message in browser from the viewer context menu (right-click to display this).
Occasionally, an errant message may lock up MailCOPA when being loaded into the viewer. If you have the autoviewer open MailCOPA will always lock up when this message is selected (or the folder is selected that contains this message). The solution is to close the autoviewer (Configure Preferences General). You can then examine the message source and decide what to do with it - often this will be deletion because many such non-standard messages are spam.
Some mailers and mail lists (and many spam messages) use a non-standard format for the date and time. Such messages may not be immediately visible in the message list because the non-standard time gets interpreted as 00:00, thus placing the message at the top (or bottom) of the message list if it is sorted by date. Clicking the Unseen tab and scrolling to the top or bottom of the list should find them
Browser Links
When a link is displayed in a message in the viewer, it will be highlighted just as in a Web page, and clicking on it will start the default browser (most often this is Internet Explorer) and fetch the page linked.
However, one or two instances have been seen where the page was not fetched correctly. This is because the link in the message is faulty, and we have no control over this unfortunately.
Large Fonts
If these are in use (Control Panel Display Settings Advanced General), then the labels for the folders and the columns in the Message List may be too big, or misplaced. This version of MailCOPA does not allow changing the fonts or font-sizes for these (although those for the viewers can be).
It is anticipated that more flexible handling of these fonts will be introduced in a later version of MailCOPA.
Use with Norton Anti Virus
This problem may exist with other anti-virus products, but see also the page on Use with AVG Anti-Virus.
Later versions (2002 onwards) intercept outgoing mail at driver level to check for viruses. If MailCOPA is configured to hang up the DialUp Connection when finished, it may hang up before Norton has finished checking the message, and it cannot then be sent.
The only known way around this problem (which is presented by other mail software too) is to uncheck the option to hang up when mail has been sent (Configure Preferences Disconnect when done).
Also, the use of the Send Now button will hang up the line immediately after the message has been 'sent' (whatever the setting above), which leads to the same problem. We do not recommend the use of Send Now with Dial-Up Networking.
Toolbar or Window Problems
You may find that the arrangement of one or more of the toolbars is not as you want it, but you are unable to unravel the problem. The menu option View Toolbars Restore Default Layout will return them to their original arrangement, when MailCOPA was first installed.
Similarly with the windows - View Windows Restore Default Layout will restore them to the arrangement when MailCOPA was first installed.
The Temp folder becomes full
This is rare, but may happen. You may well get a warning message from MailCOPA if this is the case, and a particular operation depends on access to this folder. If this should happen, the operation will be ended gracefully without loss of data.
You are advised to consult your Windows documentation for help on this area, but the following may be useful:
The solution is to reduce the number of files in the Temp folder - be wary about deleting files that were last modified today, they might be in use by running applications, and any files with the extension ._sm as these are used by MailCOPA.
The location varies between different versions of Windows, and can be found by entering %temp% into the address box of Internet Explorer.
