Outlook generates MAPI_E_TIMEOUT error during certain operations
Issue encountered
You receive one of the following errors:
0x80041204:er_network_timeout 0x80040401: MAPI_E_TIMEOUT 0x80048002: 'This task was cancelled before it was completed.'
Solution
One common cause of these problems is the Exchange Extension property pages Add-In of Outlook. This should be disabled.
Go to Outlook’s Options > Other tab > "Advanced Options" > "Add-In Manager" and disable 'Exchange Extension property pages'.
Restart Outlook after making these changes. If you continue to experience problems, please report them to Kerio Support.
