OLKeeper reliably prevents users from closing their Outlook window and thus possibly missing reminders or e-mails.


By default, Outlook 2007 doesn't send categories with your e-mails. That is, you can still categorize the item, but the receiver doesn't see that.

With an entry to the Registry you can get the old behaviour back:

For Outlook 2007:

[HKEY_CURRENT_USER/SoftwarePolicies/Microsoft/Office/12.0/Outlook/Preferences] 'SendPersonalCategories'=dword:00000001

For Outlook 2010:

[HKEY_CURRENT_USER/SoftwarePolicies/Microsoft/Office/14.0/Outlook/Preferences] 'SendPersonalCategories'=dword:00000001

For Outlook 2013:

[HKEY_CURRENT_USER/SoftwarePolicies/Microsoft/Office/15.0/Outlook/Preferences] 'SendPersonalCategories'=dword:00000001

For Outlook 2016:

[HKEY_CURRENT_USER/SoftwarePolicies/Microsoft/Office/16.0/Outlook/Preferences] 'SendPersonalCategories'=dword:00000001

Determine the "identity" of your emails. Set with SAM the sender and the folder folder for sent items with the help of rules.

Download Reg File

You might download a *.reg file. Save the file to your computer, unzip it, then double-click on the reg file. That will add the entry automatically to your Registry.
