I'm trying to troubleshoot a user who is using Outlook 2010 on a brand new system which is a 2.67Ghz i5 system with 4GB RAM, so the hardware performance is a non-issue. We're running Exchange 2010 SP1 at the backend.

The problem is that this particular user has a huge amount of people she is delegate for and looks after a number of calendars for various people. On her previous Outlook 2007 machine, everything was nice and fast, after migrating to 2010 however, it's just slow to use Outlook in general, not massively slow, just a couple of seconds delay switching between folders whereas 2007 was instantaneous. Wouldn't be a big problem for most people but for such a high user who is used to Outlook being able to instantly accept input, she's finding herself wasting a lot of time.


We've tried deleting her OST, recreating her profile, checked all the PSTs were error-free and in 2007 format, ran a compress on them (she has 2 PSTs approx 3GB each).


I've seen various mentions of Outlook 2010 just being "slow" around the net, but I've not been able to find any suggestions as to why this is the case, or ideas to fix it.


The next thing we're contemplating trying is deleting & recreating her exchange account in case there's some odd setting in there somewhere, but who knows what sort of of problems this might cause.        

There's no other apps of any merit running in the background, even when it's "thinking" the CPU load rarely exceeds 30% and that's just Outlook, when idle it's always sub 10%. That said, it looks like Outlook is a singlethreaded app which seems a bit poor. 

Any suggestions would be greatly appreciated, she's getting very frustrated with Outlook, and I'm getting very frustrated with her constant calls about new little niggles she's found.

Does she have any add-in's installed for outlook? Also is the 'Used cached Exchange mode' ticked in her Outlook under her Account settings?




Do whatever you want to do man.

No addins, and cached mode is enabled. Tried disabling it, but didn't help.

Are you running Service Pack 1 yet?

Tried running Defrag on that drive?

Use CrystalDiskInfo to see if the drive is reporting any errors too.

I should've mentioned that it's an SSD drive as well, which should further reduce chances of the hardware being the issue.

We've not rolled out Office 2010 SP1 as yet - still awaiting word from the global team. The underlying OS is Windows 7 SP1. I can't see that SP1 provides any performance fixes to Outlook specifically, but it may be something that we could look into. I note that it _does_ list fixes to a couple of other minor issues we've identified though.

It is. Everything else on the system is fast, it's only Outlook that seems to have performance issues.

Hi, I also have noted a couple of clients who have complained of slow outlook 2010, again new or near new i5 HP laptops everything else flies. In the end with one she complained so much I rolled it back to 2003 problem fixed and the client felt more at home with the old interface, so much for progress.

I'd more than happily roll it back to 2007, but they're not so keen given that upgrading everyone to 2010 seems to have fixed some of the calendar appointment inconsistancies (which I suspect are caused by the mobile devices that they're remotely accessing their exchange account with).

I recall dealing with similar issues in earlier versions of outlook which were traceable to authentication failures of one kind or another, in that outlook had to wait for the first method to time out before querying the next method. There is a windows resource kit tool that checks workstation/domain network authentication is 100% complete - the basic place to start. Taking the machine out of the domain and rejoining after a restart usually fixes that sort of thing. Share authentication and allowable NTLM authentication modes are the next level up to examine. Hope that helps.

Are you use Outlook over HTTP or MAPI? Try Changing the connection type

Also Reduce the size of the mailboxes by archiving, Exchange 2010 Server archiving is nice new feature. Also with Outlook 2010 each mailbox opened will be cached, so Outlook can spend lots of effort check each mailbox and folder is up to datr, and also larger PST's run slower

Typically if we have decent exchange server and PC is always on the LAN we leave Outlook Cached mode unchecked

You are not alone, I can reproduce the same issue at work on every computer (and every computer is running 2010)

As you add more shared calendars to your calendar view the slower moving around it gets.

As of yet I am to find someone who has fixed the problem.  We have had our senior engineers look into it and no luck.

This is a list of things we have tried:
- Re-install Windows - no change
- Create brand new user/mailbox - no change
- Updated exchange 2010 to most recent updates/patches - no change
- Rolled Exchange 2010 back to RC - no change
- Tried Windows XP - no difference
- Built fresh Windows 7, Vista, XP Virtual machines - no change

I have read articles about Exchange 2007 also having the issues with Outlook 2010.

Hi, we also have noticed this issue. We logged a case with Microsoft (not sure we got anywhere)
My engineer tells me the problem *may* have been resolved with the installation of Exchange 2010 SP2

Please try that and post back if it helped you.

Unfortunately upgrading the exchange server is above my pay-grade, plus theres ~900 users involved so it's fairly non-trivial.

Mailbox size is restricted to 200MB, anything beyond is archived to PSTs.

We do use HTTP, I'll see if switching to MAPI makes any difference.

Outlook 2010 here on Core i3's and Core 2 Duos with multiple mailboxes, many of which contain 10,000+ messages per folder.

Performance is good on our very old exchange server, but we are upgrading to latest version of Exchange next week.

Have you noticed any issues with the new version of Exchange?

Updating the system to Office 2010 SP1 helped the speed issue a bit and resolved a couple of quirks, but it still seems to be signficantly more sluggish than Outlook 2007 was with essentially the same usage.

Plus it does a lot of "odd" inconsistant things which only the _really_ heavy user(s) notice so I'm rarely able to replicate them in my own testing.
