He encontrado una guía muy interesante de troubleshooting para MS Office Outlook. Aquí la dejo:
There is an Office update 933493 to improve the general responsiveness of Outlook 2007 during common operations. Please check if you have installed this update (via Microsoft Update or manually download/install it.)
You can download the update directly from the Microsoft Download Center at:
Update for Outlook 2007 (KB933493)
http://www.microsoft.com/downloads/details.aspx?FamilyID=c262bcfd-1e09-49b6-9003-c4c47539df66&DisplayLang=en
After installing this update, check if Outlook is working fine now. If not, let's come into Outlook safe mode to see if it workaround this issue.
Step 1: Outlook safe mode
=======================
1. Quit Outlook. Click Start menu, and click Run.
2. In the Open box, type: "Outlook /safe" (without the quotation marks).
Notes: There is a space character between Outlook and the forward slash (/).
3. Click OK. Is Outlook working fine under Outlook safe mode?
If the problem doesn't occur under Outlook safe mode, please restart Outlook in normal mode and remove Add-Ins
----------
1. On the Tools menu, click Trust Center Settings, and then click Add-ins.
2. In the Manage box, click the Com Add-ins, and then click Go.
3. In the "Add-Ins available" list, click to clear the check box for any add-ins that are installed.
4. Click OK.
Does the issue still persist? If so, let's go ahead and perform the next step.
Step 2: Rename the Cache Files
===========================
Search for the following four files and rename them by changing the file extension from ".dat" to ".old". These four files are temporary cache files that Outlook 2003 loads on startup. (Be sure to check the "Search hidden files and folders" box under "More advanced options")
outcmd.dat
extend.dat
frmcache.dat
views.dat
Generally the files can be located in the folder C:\Documents and Settings\<LogName>\Local Settings\Application Data\Microsoft\Outlook\. Some of them may not exist, please ignore it.
Note: The folder is hidden by default. Please use the following method to show it:
1. From the Start menu, go to Settings-->Control Panel-->Folder Options.
2. Go to View tab and select "Show hidden files and folders". The hidden folder will be shown then.
3. Start Outlook to see if the problem is resolved.
If the problem is still there, try step 3.
Step 3: Create a new profile
========================
1. Click Start menu > Control Panel
2. Double-click the Mail icon
3. In the Mail Setup dialog box, click Show Profiles. Click the General tab, click "Prompt for a profile to be used".
4. Click Add.
5. In the New Profile dialog box, under Profile Name, type a descriptive name for the new profile, and then click OK.
6. In the E-mail Accounts dialog box, select "Add a new e-mail account" in the e-mail options, and then follow the wizard to configure your email account.
7. Start Outlook with the new profile and perform a test. For detail information, please refer to the following KB article:
