2 hours waiting for a message trace in 0365, criteria was 1 recipient 1 day earlier this month. This is almost as frustrating as waiting for mysterious un-configurable SharePoint online services to run once every 24 hours to see if a change you made upstream fixed a problem...

it is, if you’re unlucky you get to wait even longer. I did a few extended message traces a couple months back when they broke OME message routing, an MS engineer was working with us while those traces ran, they clearly took ages. He really didn’t like waiting 5-10 hours, swearing up and down it used to be much less. I don’t remember such a time but he said he’d take it up with the product group or whatever they’re called now because potentially waiting an entire workday is insane. So yea this is still what is,

I'm hoping you guys might be able to help me with an issue a client of ours ran into the other day.

My client has an Exchange 2013 environment with about 60 mailboxes. The other day they managed to incorrectly implement a retention policy against all mailboxes which removed ALL mail prior to 9/1/17. I've spent about 4 hours troubleshooting this and I've removed the bad retention policy. I"m now trying to figure out if the old emails can be restored to each mailbox. I've found that the New-MailboxSearch command is able to see the older emails which is the good news.

My problem is that I don't know how best to scale this "fix". The New-MailboxSearch command requires you to copy everything over from the target inbox over to another inbox, you cannot specify the same inbox to restore to. This means I have to copy everything over to a temp mailbox and again back to the user mailbox. Additionally, it appears that the maximum concurrent searches is capped at 2 and there's no way to queue that up. Furthermore, this approach still requires users to drag all of the emails out of a recovery folder in their inbox and move them to whatever folder structure they had set up previously after the search and copy operation finishes.

Is there any easier way to go about this?

Are the messages not recoverable from Outlook? You could have the customers recover their own data if they want it or an admin can be given full mailbox access and recover for them. It'll take several hours but it will likely be faster than trying a programmatic approach with just 60 mailboxes.

If you're intent on some scripted solution you could do it through the ews api using a service account with full access to the mailboxes. Unless you're familiar with the api though it'll likely take a couple days to develop and test.

It appears that these messages have some sort of hidden attribute applied to them. Even their main administrator who has full inbox permissions cannot see the missing emails in his local inbox.

I spoke to a exchange guru and got some sagely advice to help me with my problem.

In case anyone else is curious, the answer I got was to do a point in time restore to a temporary recovery database and then use PowerShell to copy from the recovery database into the current exchange database. The way I was doing it technically works, but it's time consuming and it won't retain the proper folder information for each email (everything would have to go under inbox).

Hoping someone can point me in the right direction here:

The program I support has an integrated e-mail client, Mailsender. One customer has Office 365. When they send an e-mail inside their domain, either from Outlook or Mailsender, all of the images in their signatures look fine. When they send from Outlook outside their domain, everything is fine. When they send from Mailsender outside their domain, the images show as attachments to the e-mail and the body of the message shows a broken image placeholder.

If I look at the source of an e-mail sent outside the domain using Outlook, the image tags look like what I would expect:

<img src="cid:image001.png@12345678.87654321">

The e-mails from Mailsender look like

<img src="cid:A73523B896F32342357ACD@CANPRD01.PROD.OUTLOOK.COM">

I'm at a loss as to why this is happening and if it's a bug in our program or something on their server they need to adjust. I can't really send it to the developers until I figure that out, and our organization doesn't have any o365 accounts to test with. Google turns up a lot of people asking how to embed images in their signatures, but the closest to this issue I can find is this and there's no real answer on it (the images are all being sent with the correct mime type).

Any thoughts?

What does the MIME structure of the outgoing mails look like? Especially any Content-Disposition headers for the image parts.
Also does Mailsender use SMTP or some Exchange-specific service to inject the messages?

I'm trying to get the guy I'm working with at the client to send a message directly to Gmail, because I'm not sure how to check that in Outlook. But the e-mails he sent to my Exchange that I then forwarded to Gmail have this:

code:
Content-Type: image/png; name="image001.png"
Content-Description: image001.png
Content-Disposition: attachment; filename="image001.png"; size=8172; creation-date="Wed, 17 Jan 2018 15:01:55 GMT"; modification-date="Wed, 17 Jan 2018 15:01:56 GMT"
Content-ID: <0C7E268912A77547B2CAE21524EA02B9@myworkdomain.com>
Content-Transfer-Encoding: base64
Mailsender uses MAPI to basically use Outlook to send things. Sorry if I'm not stating this correctly, that's my understanding of how MAPI works.

In Outlook 2016 you can see the entire email with headers, etc. if you open the email into its own window, then go to File, Info, Properties.

And then paste the headers into https://testconnectivity.microsoft.com for a more easily parsed view of the data.

When I do that, all I get are the headers, none of the content. I can paste that here, but I'd rather not paste the whole thing since I'd have to redact a lot of stuff.

e. I found 3 other customers using o365 who have the same problem. That was enough for me to fob it off on development, so i'm happy now.

I've been automapped to the root of a mailbox that I don't want to have access to (it's a room calendar, I'll just set the default permissions on the calendar folder to reviewer). But the permission seems to have been granted to a security group that I'm a member of, so I can't just remove myself from the account ACLs and have it detach from my Outlook, since I'm not explicitly granted permissions.

How do I remove this from my Outlook? I am an Exchange tenant admin so I'll have permissions to do whatever the solution ends up looking like. Not keen on revoking permissions for the entire group since that's going to affect other people.

Edit: Should have Googled harder. Explicitly adding access to the mailbox but setting automapping to false cleared it out after a short delay (cached Exchange). Then I just removed that explicit ACL.

One more month and our remaining exchange 2010 servers will be gone. Remaining on-prem exchange infrastructure will be two Exchange 2016 servers in HA for internal SMTP relay outbound to Proofpoint/O365 and ECP for user maintenance of attributes to sync to O365.

you found it out already but groups should never automap (until this silently becomes a ‘feature’ one day)

Quick dumb question - with a local Exchange 2016 server, if I create a junk mail rule in Outlook 2016, is that stored server side or client side?

server side, you can edit them server side as an admin too

Does anyone know if there's an easy way to migrate PST files out of Microsoft Cloud? I'm half expecting there to be a powershell commandlet like Migrate-PSTFilesFromCloud.

I could have sworn I've heard people talking about it before, I can't remember if there was an easy way or if people just said "some 3rd party tool will do it for $5 per mailbox."

turn on litigation hold indefinitely so nothing gets deleted ever, use ediscovery search to stick the entire thing into a separate box the user can't reach if you need to give auditors access
