All versions of eWay-CRM
Check whether the MS Outlook profile is set as Cached mode or Exchange online: Control Panel > Mail > Show Profiles... There you can choose MS Outlook profile where the error appears. Usually there is only one profile called "Outlook".
Now click the Properties button and then the Data Files... button. Select the used profile and open its Settings.
Go to the Advanced tab and check whether the Cached Exchange Mode Settings is enabled. If the Use Cached Exchange Mode check box is not marked, mark it.
This setting should be consulted with IT department of your company. If the MS Outlook runs on the computer terminal where the Exchange server is too, the setting should be inactive. Problem will be somewhere else.
