"I do not know what happened to my wife’s Outlook. It runs so slowly; right from launching the program to using it. We hope it’s not a virus! Please, I need a good tutorial for repairing issues that can cause Outlook slowing down."
Is your Microsoft Outlook running (or should I say “crawling”) slowly? The slow speed is most likely caused by Microsoft’s tons of features. It should not take so much time to load one profile. Hopefully, Microsoft optimizes its application. We, however, have some tricks and fixes for resolving the problem of Outlook slowing down.
Please read this guide to the end to discover the easy ways to make your MS Outlook run fast.
Step 1: Launch Outlook, but press and hold the CTRL key while doing it.
Step 2: Doing that makes Outlook open in Safe Mode. If the program is slow while running in Safe Mode, then it means that an add-in might be the cause of Outlook slow.
Step 3: Click the “File” menu.
Step 4: Hit “Options”.
Step 5: Select “Add-Ins”.
Step 6: Find the “Manage” button down the list.
Step 7: Click “Go”. A screen will be shown. Uncheck it.
Step 8: Disable add-ins.
Step 9: Finally, close Outlook and start it normally to test if it is resolved. If solved, then start to enable the add-ins one-by-one. If it fails, mark the add-in that you added last and uninstall or reinstall it.
A corrupted PST file is one of the most common causes of Outlook being slow, because these files get damaged easily. Outlook is great, as it has a utility for fixing PST files.
To locate this tool, check one of the following locations:
- Disk drive:\Program Files\"Office version"\root\"Office version“
- Disk drive:\Program Files (x86)\Microsoft Office\"Office version"
- Disk drive:\Program Files\Microsoft Office\"Office version"
- Disk drive:\Program Files (x86)\"Office version"\root\"Office version"
When you see the tool, run it and browse for the PST file. To search for it, navigate to “Data File Properties” and hit “Advanced”.
You really do not need them, except one or two. To disable all the add-ins, run Outlook with elevated privileges (as administrator). Follow the steps below:
Step 1. Navigate to C:\Programs\Microsoft Office\OfficeXX, and locate Outlook.exe. Right-click it and click “Run as Administrator”.
Step 2. Allow Outlook to load. Next, click “Tools” on the menu bar and hit “Trust Center”. From the left-hand menu, select “Add-ins”. For new Outlook versions, you can find “Add-ins” by clicking “File”, and click “Options”.
Step 3. At the bottom of the “Manage” dialog box, click the “Go” button to reveal a list of all the add-ins.
Step 4. Select all the add-ins, except for “Windows Indexing”.
Step 5. From the dropdown, choose “Exchange Client Extensions” but leave Exchange add-ins enabled if connected to a corporate network.
Microsoft added useful features to the more recent versions of Outlook. These Outlook versions come with built-in tools for shrinking the main PSPT file, as well as cleaning it up. To access Mailbox Tools, follow the mini guide below:
Step 1. On the Outlook window, click “File” and select “Tools”.
Step 2. There, you will see the following options: Mailbox Cleanup, Empty Deleted Items Folder, and Clean Up Old Items. Select “Mailbox Cleanup”.
Step 3. In Mailbox Cleanup, you will find tools for archiving emails, clearing the deleted items folder, etc.
