Migrated MAPI Permissions?

Leud — Wed, 29 Apr 2009 09:30:02 -0800

Exchange - How does it handle Outlook MAPI permissions when migrating users from one domain to another? So the background is we've got two domains, Domain A and Domain B. Environments are all windows server 2003, Exchange 2003.

Currently users are on Domain A and have mailboxes there, we are migrating users to Domain B, disabling the Domain A account but leaving the mailboxes on Domain A. (This is not going to change for some time).

The accounts are moved over with sIDHistory maintained so NTFS permissions etc all work, the Domain A Mailbox permissions are set with the Domain B accounts as full access and associated external accounts.

My question is how do MAPI permissions work/carry over? If Bob Smith on Domain A has added Joe Bloggs using MAPI permissions to their outlook inbox, will this work once Joe Bloggs has been moved to Domain B?

The MAPI permissions are seperate from AD and I suspect don't check for sidhistory? Looking for confirmation on this.

Thanks,

Migrating from Exchange to Google Apps

Migrating from Exchange to Google Apps. Initially is it better to forward emails from Apps to Exchange, or the Exchange to Apps (before getting rid of Exchange altogether)? I'm more interested in the reliability of the migration so that users do not experience interruptions and technical issues are minimised. I'm sure performance and security is the same either way.

I've had a look at the following but no luck:
Mefi: Transfer-Gmail-to-Google-Apps-Gmail
Google: guide-for-migrating-to-google-apps

Any other migration tips will be handy, as I read emails and contacts migration to Gmail can be a huge task...

Many thanks MeFi!

What would migrating an Outlook Exchange email system with Google's business Gmail? Google's Gmail for business seems like it has some potential and I am in the process of possibly converting the company!

Any advice on what could be involved such as drawbacks or implementation process or method will be useful.

Thanks mefi.

User stats on Exchange 2000?

Microsoft Exchange 2000 : is there a built in function or any 3rd party utility that would allow me to export a list of all mailboxes and would include info like User Logon Name and mailbox size? The company I work for was purchased by a megacorp and we'll be migrating all of our users from our Exchange server to theirs. While we have a 150mb limit, they impose a 100mb restriction on mailbox size. There are, of course, 'special' users that have anywhere from 200 to 500mb or more; therefore management is looking for a spreadsheet with basic statistics of our Exchange server users.

I'd love to be able to export some kind of list into csv (or anything else that I could open in Excel and work with) that details usernames, mailbox size/limit, and any other info that might be useful for pre migration planning. If there's any Exchange built-in function or a third party utility that could do this for me, I'd love to know about it!
