Caching too many Public Folders
Public Folder search is an incredible tool, especially for collaborative work. However, it can also create serious problems for Outlook and search too many public folders are added to favorites.
Public Folders tend to be on the larger side, so be very careful that the selected public folders cache are not very big. The data in these cached folders will be downloaded into an ost-file onto the local hard drive. If that file is exceedingly large, it may result in poor search performance and even connection problems to the Exchange Server. The key is to make sure to not to cache too many folders, and if only one Public Folder is cached, then make sure it is not huge.
If after setting it all up Outlook is running slower than usual or connection problems are occurring, then try limiting what type of files and content are being indexed.
