If you are receiving irregular issues of the ComException type during work with eWay-CRM, e.g., during synchronization or during opening and saving, it is possible that this issue is connected with the damaged MS Outlook profile.
All versions of eWay-CRM
Option 1: Try to repair the data file
In the installation folder of Microsoft Office, there is the SCANPST.EXE file that enables you to scan and repair issues in the data file that is related with the email address. In some cases, this tool can solve the problem.
Option 2: Creating a new profile
The most effective way is the resolution recommended by Microsoft. It is the recreating of the proflle and remapping of email addresses to the new profile.
After email mapping, MS Outlook will synchronize all data. Microsoft Exchange, Kerio and other similar services will download all data - emails, tasks, calendars, etc. If you are using IMAP or POP3, these services synchronize only emails, because they don't enable more. Your tasks, calendars and others will remain in old profile.
To create a new profile, go to Windows Control Panel and select Mail, then click the Show Profiles... button. In the new window, click Add... and follow the guide.
Option 3: Deactivate other add-ins
