Holy poo poo, after deleting a bunch of corrupted messages out of tha tusers mailbox, the O365 sync finally completed and it's ready to run every 24 hours. Boss is dragging his feet approving the certificate for ADFS but at least I've got some progress!

Ok, just a quick question... So we have multiple email domains like domain2.com, domain3.com, and domain4.com. Is there anything preventing me from doing a cutover on those MX/SPF records first before I cutover our main domain domain1.com (which is also our internal domain name, I didn't set it up!)? All domains are set up as federated. This would be great for me because I can bring our smaller companies onto office 365 first, reconfigure their blackberries, iphones, and outlook, and then move over our main company. Will this effect our daily sync that goes on from O365 to my on premises server?

Briantist posted:I don't know enough about the O365 process to say whether it would affect its intricacies (especially the daily sync and all that), but in general you shouldn't have a problem cutting over one of the domains, as long as the 365 side is ready to receive e-mails from the outside world. I've done that type of cutover moving between many different types of mail systems, but never exchange to hosted exchange (and never a system where the two were "aware" of each other like this). They're not really aware of each other besides O365 pulls nonsynced email from our onsite Exchange 2010 server, as far as I know, this isn't bidirectional. O365 is ready to receive emails for these accounts, I licensed them up and they have some downtime next week so I'm going to do it for them and see how it goes (only 2 users). They both have blackberries which will need to be wiped and then reactivated, which is probably going to be a bigger pain in the rear end than doing the actual cutover, but hey, here we go. I set the TTL for their MX records to an hour so when the cutover happens it should be pretty quick.

Does anyone here have a link to the proper way to create new users once you cutover to O365? I've been reading even more about the cutover process and once I get everything over to O365 w/SSO and DirSync, you have to convert your users to Mail Enabled Users (otherwise, once you decommission onpremesis exchange, you run into problems). From what I can tell, the only way to do this is to use the attribute editor in AD or I believe you can also use powershell? It's not the biggest of deals but it would be nice if there was a way to create a "New -> MEU" right out of the GUI. Is this possible?

It's really loving aggravating how Microsoft is treating Public Folders WRT O365. Should I just create a new shared Mailbox called Public Folders? Or do I need to create a new Room Mailbox for each room calendar? And that means everyone will have to manually add it to their outlook since I don't want to grant full access. Or can I grant full access and then granularly control permissions through outlook? Please don't say sharepoint  Thanks Microsoft.

So after a bunch of back and forth, my boss decided O365 wasn't going to work and we're going to implement a 2 server DAG for our E2010 setup. The problem is, the email server is 2008 R2 Standard and we need it to be enterprise. How hosed am I? I guess we'll have to install the server in the DR facility, migrate the email to it, point everyone at it, and then rebuild the server her with R2 Ent and add it to the DAG? Or has anyone here done an in place upgrade of Windows with Exchange installed?

Briantist posted:LmaoTheKid, what were the problems you had migrating to o365? Were they more related to your environment or the process in general? A little bit of both, combined with how hosed up the documentation is for implementing things. It just got really loving annoying plodding through tons of links to find outdated information and BPAs WRT Azure and Active Directory and creating new accounts and blah blah blah. It honestly just seems easier to go with expanding our in house server to a DAG with our DR facility.

Can anyone point me to how ActiveSync handles multiple Exchange servers? I'm going to be migrating our Ex2010 to another Ex2010 (different server name) box in our offsite hosting. Both will have all roles installed. If I point incoming mail to the new box and then slowly migrate mailboxes over to the new one, create the proper send connectors, how would activesync handle the mailboxes moved to the new box if they're pointed towards the old server? Would I need to point the devices to the new server?

I'm at the point with my mimecast transition where they're pushing me pretty hard to enable journaling. I'm in the process of eventually moving all of our email to our DR facility where there's a much beefier server and more disk space. I'm right in thinking journaling on the old machine at this point is a no go, right?

If I'm moving my mailboxes to a new server with a different name, do both servers need to be on the same rollup level? Or can I go with the newest one on the new server? I think I'm on 4 on the current one.

Yeah, that's true, and the new server is in Philly so it would be a bit of a pain to have to get down there if something locks up during the move (though Accela Express gets me there in 40 mins from NYC so its not that big of a deal)

So, I have my second Exchange 2010 server installed. Different host name, in my DR site. I've read that I don't need send connectors because E2010 is site based so they should pass email back and forth. So now I'm just a bit overwhelmed as to wha tI need to do. I guess my first order of buisiness should be to get a new cert with SAN of the new machine name, the Activesync/webmail address, AND the old host name? And I can run that alongside the current one, correct? If anyone has a link to a good guide, i'd GREATLY appreciate it, and any help/pointers/caveats to look out for.

So, after months from putting down the migration from one 2010 box in our home office to another 2010 box in our DR site, I'm getting back into it and I just realized I never set up a CAS array. Good job, me. How hosed am I creating this after the fact? I have about 50 users, so its really not the biggest of deals to go around and point them at the new CAS array.

Gyshall posted:What do they point at now? Just create a new array, with something like mail2.yourcompany.com, test it, and if it works, change the main DNS record for mail.yourcompany.com or whatever it is pointing at to look at the new CAS, if that makes sense. Right now the CAS is just the server name. I for some stupid reason didn't create a CAS for a single server when I did the initial install/migration from 2003.

Odd, everything I'm seeing says that the CAS array shouldn't be advertised outside of the network. Anyway, I'm way behind on Exchange updates anyway so my first order of business is to get both servers on SP3 and the latest rollup before doing anything.

So for about 50 mailboxes/300 gigs or so of email on 2010 SP1, about how long can I expect for downtime? My boss is traveling in Japan right now and getting kind of bitchy about this downtime but the next few months are pretty much booked solid so it would be good to have an estimate. Obviously CPU and other things factor into this, but can anyone give me an estimate, I'm seeing 30 mins to 2 hours on various sites but I have no idea what their install conditions are.

Anyone have a good cross site redirection tutorial? I'm finding a few but they leave a lot to be desired. My last step here is getting that working so I can start moving mailboxes without disrupting OWA/ActiveSync. The new server is not external facing yet, just accessible via VPN in all offices and until we're ready to cut over to it as the new server, I'd kind of like to keep it that way.

Holy loving gently caress. I got everything working. Servers have a new re-keyed cert with both internal and the external host names on it. OWA and ActiveSync Proxying works. Email flows back and forth through both servers and externally. Goddamn, can I really start moving mailboxes in a week or so? When you guys say I have to "touch" all the clients afte rI move their mailboxes, what exactly do you mean by that? And does the offline cache need to rebuild or will I be ok there?

Gyshall posted:Really depends on how they are set up now. I'd pick a guinnea pig user and see how they react to being moved (after telling them of course.) I can use myself as a guinea pig, I don't care. Unfortunately the way I originally set up was for everyone to point to hostname.domain.com and never created a 1 server CAS array (which I asked about earlier). According to various articles I've seen, if I had set up a 1 server CAS array all I'd have to do is add the new server to the array and when I do the mailbox move it just automatically flips over (which I guess is what you said). Since I have split DNS I should probably set up a CAS array for our external domain internally and then point everyone to that, and then add the new server to the array?

The Electronaut posted:New public folder set as the default on your mail DB(s)? Special mailboxes migrated? Not sure of your architecture so those are two that jump off my head at first glance. I assume you have a CAS array and your Outlook users are using a VIP for connectivity instead of a single CAS. All clients are cut over to the new server. Public folders are happily replicated. Special mailboxes are moved. SMTP send and recieve are rehomed. Firewall is set. Public and private DNS are changed to the new proper internal and external IPs. I can't really think of anything else. I'll shut it down on Monday and see how it goes.
