I am starting the planning for migrating our on-prem Exchange 2010 server to a hosted solution. I have been leaning toward Office 365 for some time, as we have been using the pro plus subscription for the client side of things for a couple of years and have heard mostly good things about it for the Exchange hosting side of things. If other people have service providers that they think are way better for hosted Exchange, please chime in.
I also wanted to build a check list of things that need to be considered when migrating and running Exchange as a hosted service.
- I am currently using Azure AD Connect (was using dirsync) to sync AD user accounts and passwords for Office 365.
- What should I use for backup of the databases?
- Service provider to perform the migration?
- Do I need additional spam filtering/ AV?
Any other tips or suggestions that I should consider or plan for are greatly appreciated.
I thought if you buy O365 from NTG they will migrate you as part of that purchase, but then again maybe I was hi that day?
FYI - This only applies if you pay for it. If you're a non-profit O365 is free and NTG doesn't receive any money for it. Just in case anyone is interested that is a non-profit.

@Dashrender Hmm. So far, from some brief googling, the ability to recover/restore seems underwhelming.
It's dependent on what you pay for. You could have the ligitation hold option enabled, which means the account is held and unchanged until a time that you turn the feature off.
Or you pay for other recovery levels, there are several great options there.

@DustinB3403 Are you referring to the equivalent of the Enterprise User CALs?

have you found any examples of someone who has lost data by Microsoft and not had it restored?

I've discussed this so many times with you, I actually said this in my head when I saw that post, LOL.

@scottalanmiller No, I have not. But I know I will get asked this- what if someone intentionally deletes messages past the deleted items retention period?
Also, what would someone use this for if everything is baked in (specifically the Exchange part)

https://blogs.technet.microsoft.com/uspartner_ts2team/2015/12/31/microsoft-partner-azure-iur-skykick-cloud-backup-offer/To me this looks like someone who is trying to sell RHEL - it's completely unnecessary. Sure you can do, but why would you? Unless you're just one of those who absolutely has to be in control of every piece.

I think the Admin has access to everything that is deleted for a period of time.

How do you answer this for locally hosted?
Do you have an appliance that saves every email flowing through your system now? It's possible someone could get a message, and delete it before you backup the system.. then a month later the boss wants that recovered - is there an option? (I guess depending on your backup situation - Exchange probably has a way for you to restore the delete items items.. then go back and find it.. but I've never don that).

@Dashrender Email archiving software/appliances.

-
@scottalanmiller So you would basically add a 3rd party archiving service?

You can, but I thought Dustin linked to something that MS offered in this same vein.

Yes, just like you do in you are doing an on premises email system. MS doesn't provide that, but you can add whatever service you like.

@Dashrender Litigation hold is usually for certain users at a time and not retroactive if something has already been removed. Kind of like half-way archiving.

Hold can't be retroactive by definition

Thanks to everyone for participating. Anything else that should be considered?

Based on your mentioned query, I would recommend you to follow Exchange server deployment assistant that is available from Microsoft team and covers all required aspects by checking the necessary prerequisites : https://technet.microsoft.com/en-us/office/dn756393.aspx
Here is another informative technet article which provides step-wise details to accomplish this task in flawless manner.

@scottalanmiller What I have seen is people losing data for a day or two but not everything. Office 365 recovery or restore for Exchange or Sharepoint is an all or nothing approach. The restore cannot be granular and that's why I enable Recycle bin on Sharepoint.
