One of my first blog posts (https://customerfx.com/article/reregister-xbar-dll-files/) dealt with how to reregister the slxotl32.dll file, which could sometimes get Xbar to show up in Outlook when it has disappeared. The commands were:
regsvr32 /u c:\users\USERNAME\AppData\Local\Infor\slxotl32.dll
See the link for the full description.
Xbar is an Outlook addin that connects Microsoft Outlook to Infor CRM software. If Xbar is consistently disappearing from Outlook, you can add values to the Windows registry to stop if from becoming disabled. The first step is to add Xbar to the resiliency list. Infor has used a few different names for Xbar in the registry, so the best way to make sure you get the right one is to make registry values for each of the three names they have used. Open regedit and navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\##.#\Outlook\Resiliency\DoNotDisableAddinList . Right click to choose New, and create a new Dword value with the name InforCRMXbar and give it a value of 1. Now create Dwords with the names Saleslogix.Outlook.Connector and SaleslogixSidebar, also both set to 1.
Now, still in regedit, navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins , and once again create Dword values for InforCRMXbar, Saleslogix.Outlook.Connector, and SaleslogixSidebar; this time setting them to 3. This insures Xbar is set to load when Outlook starts. Note that ##.# is not literal, but refers to the version of Outlook you are using (16.0 on my test system). If there are multiple versions present, it is usually the highest. These changes don’t always fix the issues of Xbar not loading, but they often do. Standard warnings to be extra careful whenever you are dealing with the registry apply.
