Hey John, we are running outlook 2007 with a exchange 2003 server, it is only the attachments and links that takes forever to open. There is no problem opening previews, there are also no add-ons installed except from the ones that are there to start with and Windows Search. Outlook hangs because other Outlook files or settings are damaged. Also, if somehow your Outlook settings are damaged (usually because of a 3rd party software or add-in), you should try to load Outlook in safe mode. To launch Outlook in safe mode, simply hold the CTRL key and double clicking on Outlook icon to run it. Start Outlook. Update information for Windows 7 and Windows Server 2008 R2 To resolve this problem for Windows 7 and Windows Server 2008 R2, take both of the following actions: Apply the Windows hotfix that is mentioned in this article. Apply either Outlook 2013 update 2878323 or Outlook 2010 update 2878254, depending on your configuration.

• Outlook Calendar Taking Long Time To Load

Hi Peter,

I’d like to confirm the following information:

1. What do you mean by saying “365 works fine”? Is the mailbox an Office 365 mailbox or you just use Outlook which includes in Office 365?
2. How many mailboxes did you configure in your Outlook client?
3. Is the Outlook data file very large? If it is very large, please try to repair Outlook data file by using ScanPST.

Based on my experience, please try the following steps to troubleshoot this issue:

1. Update Outlook to the latest version:

2. Open Outlook in safe mode by running “Outlook.exe /safe” by holding the Windows key and pressing R, then typing outlook.exe /safe in the open field and click OK. If it works, please try to all disable add-ins.

3. Create a new Outlook profile and only set up one mailbox in it, then check if it works. https://support.office.com/en-us/article/Create-an-Outlook-profile-F544C1BA-3352-4B3B-BE0B-8D42A540459D .

4. Repair your Office programs based on the Repair Office from the Control Panel part of this article: https://support.office.com/en-US/Article/Repair-an-Office-application-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b.

I am using Microsoft Outlook 2007 to access my official mails. Lately I have seen that Outlook takes a long time load, sometimes greater than 2 minutes. The outlook folder size is also not much (around 250 MB). Rest all applications, including Visual Studio 2010 load quickly and are behaving as they should. Why is Outlook slow?

OS - Windows 7 Ultimate Edition (x64),4 GB RAM,500 GB HDD

Some steps that are reported as helpful :

1. Turn off indexing on particular harddisk drive
2. Run Outlook as Administrator
3. Control Panel -> Mail, 'Data Files'button, 'Data Files' Tab, ensurethat your .pst is not mentioned.
4. With Outlook closed, renameC:Users<username>AppDataLocalMicrosoftOutlookextend.datto extend.old.

Microsoft says :

1. Reduce the size of the Exchange mailbox
2. Use an online mode profile instead of a cached mode profile
3. Split your large .pst file into several smaller .pst files
4. Use a filter to restrict the items that you synchronize from Exchange to your .ost file

More stuff from Microsoft Outlook 2007 Running Slow :

How many emails do you have, and do you use IMAP at all? Outlook has know issues with IMAP and can be slow if you have more than 5,000 emails.

I found that deleting the outlook connector addin for hotmail shortened my load time by 75%. It was taking over three minutes to load Outlook 2007. I have completely uninstalled Microsoft Live Essentials and my machine is running like it did prior to allowing the updates. Me thinks Live Essentials is a bad piece of work by Microsoft. But, what isn't.

Disable add-ins (especially the ones you never use), but start with all and then work backwards to see which slows down Outlook when enabled
