User cannot access the side panel for 'Salesforce for Outlook' due to continuous refresh

To resolve this issue
 

1. First, exit 'Salesforce for Outlook' by clicking on the SFO icon from the System tray and then click on Exit.
2. Next, close Outlook.
3. Now, click on Start and type in Outlook.exe and you should see the icon show up on the list of programs, simply add the /cleanreminders switch at the end.

You can also try to copy paste this: outlook.exe /cleanreminders

Note: In some cases, you may need to type in the full path for the Outlook.exe file. Usually it is in the Program Files folder

Path to Outlook.exe file:
C:\Program Files\Microsoft Office\  
OR  
C:\Program Files (x86)\Microsoft Office\

There should be an OfficeXX (xx is a number indicating the version of Office - Office15 folder is for Office 2013, Office14 for Office 2010, and Office12 for Office 2007).

For example, if you have Office 2013 installed then your path should be something like this:
C:\Program Files\Microsoft Office\Office15\OUTLOOK.EXE

4. Once Outlook opens, try to reproduce the issue. The issue should be resolved. You can also try to run Outlook using the /resetfolders switch first, then exit Outlook, and then run it using the  /cleanreminders switch.
