That is PRECISELY what happened to me. I tried every "fix" that has been posted here and elsewhere and could solve the problem until I opened the document with German words in it. I routinely use documents with German words in them AND I still really need a Custom Dictionary for English. There was never any problem with this using Office 2004, and I would dearly love to just go back to it. I have tried to do that, but then a problem with Entourage surfaces, and I cannot get the 2004 version to use or import all my addresses, emails, and calendar from the 2008 version (also having tried multiple things posted by others). I am at a total loss am hoping for guidance with either fixing the "Custom Dictionary Bug" in Office 2008 or being able to successfully go back to Office 2004 without losing everything from Entourage. Yes, I know where all the Entourage files are, and I even have them backed up, but I still cannot get the 2004 version to recognize or use the 2008 Main Identity. Pardon me if this has gotten long, but this problem has been going on for a long time, and I cannot seem to get any answers that work. Thank you!
Option 1: Call tech support. You get two free calls to tech support with your legal retail purchase of Office 2008. They should be able to help you figure out what's going on with your custom dictionary issue. You'll just need your Product ID when you call, which you can get from any Office app in its About box.
Option 2: If you do decide to go back to Office 2004, you're going to need to do some work to get your Entourage 2008 data back into Entourage 2004. We did a lot of work on the database in Entourage 2008 to improve performance and reliability, so an Entourage 2008 database can't be read by Entourage 2004. So you'll need to export stuff.
* For your mail folders, drag them from the Entourage 2008 folder list to somewhere in your Finder. This creates .mbox files, which can be read by Entourage 2004. If you have subfolders, you'll have to drag those out separately -- the .mbox format doesn't support subfolders.
* For your address book, you have two options: enable Sync Services in Entourage 2008, and then let your Entourage contacts be read by Address Book. Then, in Entourage 2004, make sure you update to 11.2 or later (current version is 11.5.4, if I recall correctly), and enable Sync Services in there. Entourage 2004 will see the contacts in your Address Book, and will download them automatically. Alternately, if you don't want to go through Sync Services, you can drag your contacts from Entourage to somewhere in your Finder. This creates .vcf files, which can be read by Entourage 2004.
* For your calendar, you can do the Sync Services thing. Or you can drag all of your calendar events to somewhere in your Finder, which creates .ics files that can be read by Entourage 2004.
* For your tasks and notes, drag them to your Finder.
* For things like rules, the mailing list manager, and Projects, I'm not sure off the top of my head how to get those from Entourage 2008 and into Entourage 2004. If you're using those, I can try to figure out if it's possible or not.
