Outlook upgrade on server

Created: 17 Apr 2013 • Updated: 05 May 2013 | 4 comments
This issue has been solved. See solution.

Currently running EV 9.0 SP1 on a 2008 R2 Server with Outlook 2003 installed. Exchange is 2007 SP3 RU10.

Are there any reasons for/against upgrading Outlook to 2007 ?

Hello Paul,

No, no reason. You only need Outlook 2007 if you plan to archive Exchange 2010/2013

I do advise to apply SP3 on Outlook, plus a hotfix to accomodate mails with >2048 recipients/attachments.

Outlook 2003 is faster with archiving from Journal Mailboxes btw.

Just keep in mind Microsoft's product support lifecycle:

So Outlook 2003 will be supported until April 2014. Then you will *have to* upgrad to get security updates.

Thanks for the relpies.

Michelz that was the thinking behind upgrading really. I figured we shouldnt really be using an Outlook client thats 10 years old :-)

Having said that GertjanA makes the point about slower archiving from Journal mailboxes. I wonder how much slower and will this cause us any issues ?

Hello Paul,

It all depends on the numbers...

Check this:

How many items are you journaling, any idea? I am not sure anymore, but I thought archiving slows down a little due to a difference in mapi in OL2007, and also the way messages in the journalmailbox are 'grouped'.

You do need OL2007SP3 with hotfix (or perhaps there is already an SP4, don't know)
