If you find that Outlook is crashing after installing PoliteMail, the most common problem is a corrupt Outlook PST file.

While Outlook may run fine most of the time with a corrupt PST, because PoliteMail reads the Outlook PST often, the corruption results in more frequent crashes.

Follow these steps to repair your Outlook PST/OST file(s).

Microsoft provides a tool specifically to fix corrupt PST files, and once fixed, PoliteMail and Outlook typically cooperate without crashing.

Some of the other typical issues related to Outlook crashing:

  • Anti-virus software with email-scanning add-ins
    (suggestion: turn-off out-bound email scanning)
  • Out-of-date Outlook/Office Software
    (use Windows update or Office update to install the latest updates from Microsoft)
  • Out-of-date Windows software (or Windows component DLLs)
  • Damaged/Corrupted Outlook PST/OST files
  • Problems with your Outlook profile
  • Conflicting add-in software (multiple add-ins)
  • Registry Issues (damaged software installations – bad data with HKEY_CURRENT USER)
  • System specific problems (memory/hard-drive/system software)

Some of the methods to resolve these issues are:

  • If the crash occurs on a specific mail item (or calendar event), then remove/delete that item
  • Run Windows Update and Office Update
  • Scan and repair the damaged or corrupted Outlook PST/OST files
  • If you have a damaged profile, you can restart Outlook using the /cleanprofile switch
  • If you are running desktop security software (such as Norton, McAfee, AVG or others) that provide email anti-virus scanning, these may interfere with the PoliteMail processing (as they compete to use Outlook objects).  You will want to turn off any outbound email scanning (this prevents you from sending viruses, but you will still be covered from receiving any). You will also want to uninstall or disable any Outlook add-ins these tools have installed – they can still provide incoming email protection without being embedded into Outlook.  Once these changes are made, restart your system.To determine if the problem is your Outlook profile, create a new Outlook profile, then run Outlook when signed into this profile. If it doesn’t crash, then add your existing PST file(s) to the profile. If it still doesn’t crash. Modify the profile and use this as your primary Outlook login profile, then delete the old one. If however, Outlook crashes after you add the PST, then follow the directions to scan/repair your Outlook PST/OST files.
  • Add-in software may conflict with each-other trying to use the same Outlook resources.
    You might start the resolution by restarting Outlook using the /noextensions switch or /safe mode, and if that
    stops the crashing, then use Outlook Tools > Trust Center > Add-ins (on the left) > Manage COM Add-ins GO (at the bottom)
    and selectively turn on/off the add-ins you actually use, to determine which is causing the issue/conflict. Remove any unused add-ins.
  • If Outlook continues to crash after adding a new profile, then you might try creating a new Windows user profile. Then restart your computer and login using the new Windows profile, then start Outlook and login. If the problem is resolved, make this your primary Windows login profile and delete/remove the old profile.
  • Registry Issues may sometimes be resolved by uninstalling/reinstalling all related software (including Outlook/Office).
  • To determine if your issue is system specific, trying installing and running the software on another computer. If the problem doesn’t occur, then consider replacing faulty RAM, hard drives, performing a Windows clean boot, etc.
