If you are having this issue, its a good idea to turn off the anti-virus for Outlook and see if the problem goes away.

Instead of dealing with Outlook crashes, crazy error messages, memory hogging or wasting time waiting for Outlook to load, why not follow my advice below to make Outlook fast and responsive.

All your emails, tasks, calendar items, business contacts, etc.

To reduce memory usage and make Outlook fast, that database needs to be small and optimized.

I would check the mailbox size and if its anything over 500 MB, you should turn on AutoArchive or delete any emails that are taking up a large amount of space.

Also, make sure to empty out the deleted items folder afterwards as that still takes up space.

Thats why its a good idea to turn on AutoArchive because it will take care of it automatically without any intervention.

A lot of programs love to install add-ons to Outlook automatically, such as Adobe, EverNote, Wunderlist, etc.

Even Microsoft adds a bunch of stuff that I normally disable like Skype, OneNote, SharePoint, etc.

To actually disable an add-in, you have to select COM Add-ins in the combo box at the bottom and click Go.

Another window will popup and you can uncheck the items you dont want.

If you dont use this, disable it so that it doesnt load every time Outlook starts.

It will also prevent your system from scanning your emails, etc.

Yes, Google Reader was great and now that it is gone, why not use Outlook to manage your feeds right Bad idea There are still many good online and offline RSS readers that you can use other than Outlook.

You can use Google Calendar for any Internet calendars you want to follow.

Empty them out Someone like me gets hundreds of spam emails a day Thats all stored in the Outlook database and slows it down.

Click on the Data Files tab and double-click on the data file you want to compact.

Sometimes this situation never comes up, so its good to do it manually once in awhile.

It may be a good idea to disable search indexing for Outlook until you need it or delete and rebuild the index in case.

In any case, you should reduce the size of your main data files to make the index smaller.

Click on the Change on Windows searches option to remove Outlook from the search index.

Now this is very useful if you are someone who is prone to clicking on malware links or being spoofed by fake emails.

Unfortunately, even the savviest of users sometimes get tricked, so the extra protection is helpful.
