Outlook Is not responding, has stopped working, freezes or hangs

  1. Run Microsoft outlook in Safe Mode: without add-ins. To do this, open Run box from the WinX Menu, type outlook /safe and hit Enter. If Outlook does not give you any problems, it is possible that one of its add-ins is creating problems. Take a look at your installed Outlook add-ins and disable them selectively, in order to find the offender.
  2. At time, your Outlook may be busy carrying out some other processes, like synchronizing your mail, archiving old items, etc. At such times, Outlook may respond slowly. In such situations, its best to let Outlook complete its task
  3. If you have a huge Outlook data folder, then this can cause temporary freezes as Outlook takes time to open each mail or data folder.  These Outlook data files may be either personal folders (.pst) files or offline folder (.ost) files.
  4. There is one more thing you could do. Microsoft has provided Inbox Repair Tool as well as a Fix It, which lets you recover folders and items from corrupted Personal Folders or .pst files. It can even recover items from offline folder or .ost files. The OST Integrity Check Tool will help you fix corrupted .ost files. Use the Inbox Repair Tool or Scanpst.exe to repair & optimize your Outlook data.
