Slow Outlook – Add a KB explaining the compacting reason

Slow Outlook – Add a KB explaining the compacting reason

Outlook gets really slow when your mailbox hits certain sizes eg. 1.9GB (for 2007 ANSI) or 19GB (for 2007 Unicode) or 48GB (for 2010 Unicode)

Outlook gets really slow when your mailbox gets near its maximum… it kicks in a whole lot of CPU processing

The performance problems happen because the OST/PST silently takes it upon itself to compact much more aggressively than it would in a situation in which it’s got “room to spare”.

    The specifics are:

  • Outlook 2007 is 1.9GB (for ANSI OST/PST)
    The 1.9GB limit is a hard limit (it relates to a fundamental limitation in the on-disk format) and, therefore, there is no work around (short of moving some of the data to another store or deleting it and allowing compaction to run its course).
  • Outlook 2007 is 19GB (for Unicode OST/PST)
    This is not a hard limit, the file format is capable of growing larger and so there is a work-around that can be found at http://support.microsoft.com/kb/832925.
  • Outlook 2010 is 48GB (for Unicode OST/PST)
    The new defaults in 2010 are 50GB for max file size and 47.5GB (95% of 50GB) for the warn file size in Unicode OSTs/PSTs.

Note: It’s also worth looking over the information in http://support.microsoft.com/kb/940226, which covers some of the more common root causes of Outlook performance issues. In particular, the table about SSDs can be useful for setting expectations (and keep in mind that the Vista WinSAT tool is fundamentally different than the Win7 WinSAT tool and you should download the Vista one and run it on your win7 machine if you want to compare your numbers to the numbers in the chart).

Syncing Offline Address Book – need more info so we don’t think it is a corrupt ‘offline address book template file’

  • This is a weird thing… what is it doing when it gets to this point?
  • If you google, many results incorrectly seem to be talking about a corrupt ‘offline address book template file’. Am I correct in assuming that they just were not patient enough?
  • Why does it take so long?

(feels like an eternity… actually, you think it is hung… but it does complete)

Figure: Takes so long you need more information

Cater for Subscribed Newsletters (aka SPAM Level 2)

We all know what SPAM is… and Outlook seems to catch most of that fine.

But there is a 2nd level of SPAM, and that is newsletters you subscribe to, but rarely get to read… but you will ‘one day’

I would love another mailbox called ‘Junk Newsletters’ and it picked up my newsletters.

Figure: We need another folder "Junk Newsletters" and button "Not a Subscribed Newsletter"

Outlook 2010 – Help me fix this annoying behaviour of “Check Names” (aka Control + K)

If I type “Brian”

Figure: Then click "Check Names"

Figure: Then click “Check Names”

It will change to “Brian Norton”
Instead of giving me a choice of “Brian Norton” and “Brian Noyes”

Figure: The reason is it only looks in the "Global Address List"

Figure: The reason is it only looks in the “Global Address List”

Figure: I want it to also look in the "Contacts" Address Book too.

Figure: I want it to also look in the “Contacts” Address Book too.

PS: My iPhone uses the same data, but works as I expect.

Summary points

  • It should work out of the box (BTW it shows both “Brian’s” out of the box, for my iPhone).
  • This option, should be more discoverable.

Suggestion for the Outlook Team

Figure: Change the "Check Names" button to this style

Figure: Change the “Check Names” button to this style

Figure: Make the order more discoverable by adding Change Order under Check Names button that would take you to
Address book
