Also, if you have multiple Processed Mail folders on the Exchange server, you may want to start using my All Mail Search Folder that I discuss in an older blog article so that you can view and scroll through mail on multiple folders as if they were in one folder.

There are lots of other benefits of using the All Mail Search Folder, so take a look at that article.

This table shows some of similarities and differences between OE Classic, Outlook Express, Windows Mail and Windows Live Mail.

The table is based on user comments and our technical research.

In the articles above Microsoft states that to maintain performance on Exchange 2007, you want to keep Contacts and Calendar folders under 5000 items each, and that for Exchange 2010 the limit for each is 10,000 items.

Apparently in Exchange 2003, those folders have the same limits as the mail folders (2500 to 5000 items).

The indexes behind the list views in Outlook just get overtaxed and start to slow down.

That Microsoft article also says that you may see the following messages appear as Outlook seems to take longer and longer to respond: “Requesting data from Microsoft Exchange Server” or “Outlook is retrieving data from the Microsoft Exchange Server” If you suspect you are having this issue, note that you can see the item count for your currently active folder by looking in the lower left-hand corner of the Outlook window; checking that and comparing to the numbers above will help you determine if you are over the limit.

Unfortunately it’s not displayed in the Outlook client and it’s not the same as your Outlook version number. What happens when you reach the item limit—how do you know you are exceeding it?The fix is simple: spread your mail across more folders or subfolders; or archive or delete your mail off the server. Note this is a problem only on older Exchange servers—Microsoft has mostly fixed this on the newest ones.But also note that even though you may have a newer version of Outlook, the Exchange Server version your company runs behind your Outlook is invisible to you, and it could be quite old and so still subject to this issue.October 5, 2012 Has your Exchange-based Outlook mail client performance gotten slower over time? Or do you often get a message saying something like “Requesting data from Microsoft Exchange Server” that is slow to clear before you see your mail update?If so, you may have a problem that most people are not aware of: you may have reached Exchange’s , not size, and that count is not that hard to reach well before you run out of mailbox storage space.
