If you are using the Kerio Outlook Connector and Outlook hangs or freezes often, or takes a long time to start up, or often has messages stuck in the Outbox, this is a checklist of things to do.
This list is in order of most useful to least useful.
- First, delete your Outlook profile, and create a new one. Only add the Kerio Outlook Connector account. Do not add any other accounts including POP or IMAP. This is known to solve many strange Outlook problems including hangs.
- In Outlook, go to Tools-->Options-->Other-->Advanced Options. Click on Add-In Manager. Uncheck everything except for "Kerio Outlook Connector UI Extentions" then choose OK. Click on "COM Add-Ins" and be sure nothing is in there except perhaps the "Kerio Synchronization Add-In."
- Be absolutely certain that the "Kerio Outlook Connector Store" is the default delivery location in Outlook. If it is not, then it is not supported.
- Be sure you are not using the Google Desktop Search. This will work, but it can cause long hangs if there are large folders in Outlook.
- Do you have AVG antivirus installed? This is known to cause Outlook hangs. Disabling email scanning is adequate to stop this from happening.
- Do you have some other form of antivirus installed? Uninstall it on the most problematic workstations in your network (for most customers, there are only a few really problematic users in the network).
- Always repeat step 1 as necessary. When you make a lot of changes as in the other steps, sometimes it becomes necessary to create a new profile again.
