Testing O365 DLP Policy
Hi Suolon,
Not a problem - can understand the anxieties if you haven't done if before. They should not be blocked from sending out the emails unless you choose to block them.
You can find out more about the encryption here
https://docs.microsoft.com/en-us/office365/securitycompliance/email-encryption
And the recipient experience here
https://www.peters.com/office-365-message-encryption-ome/
Encryption is designed for automated encryption of sensitive data; for example school or patient PII data. Most organisation's I have worked with tend to block as they don't want this information going out over email and prefer a different sharing forum such as Microsoft Teams (I.e. guest access)
Best, Chris
Hi Suolon Hu
Please see here about DLP Policies and attachments
I would recommend that if the attachment is triggering the policy then it contains sensitive data which you would not likely want to transmit over email. If it is like an excel, word, pdf file then I would recommend the user sharing them with the recipient from OneDrive, over Microsoft Teams etc.
Best, Chris
Hi Chris,
So a few things about that.
We did not enabled External Sharing on our tenant, because we don't have a policy in place for that at the moment (that's a different journey altogether).
As for the files that are triggering the DLP, it's coming from our Professional Services department who regularly correspond with clients.... Which I'm thinking the better option in this case, and given the situation of external sharing being disabled, is probably to create a separate DLP Policy rule for them that will allow them to send attachments - probably but adding an exception on the file types being sent, and/or increase the min count? The problem is, we still want to be able to track those emails with the attachments, is there anyway to do that?
Also, another issue we're having are the GoToMeetings invites are triggering the DLP as well. The only content in those emails are the phone numbers which are triggering them - ie, false positives. In these cases, again, users are not given a prompt to override them and report them as false positives.
- It's not working for me in SCC. It's worked in AIP so I thought I will "move on" and migrate to SCC, how wrong I was. One test policy never worked, so I deleted it, now it's in "deletion state" for over two weeks - ok, not a problem, quick google search and there is a PS command but recently Microsoft removed -ForceDeletion switch (on purpose?) so I can't force delete the policy in Powershell and it clutters my dashboard which I hate btw. So I created two more test policies and the mail tips are not working, I tried everything without any success. The admin experience in O365 / Azure is very poor for me. And the whole configuration is not a single pane of glass at all. Azure here, old exchange admin there, new admin centre everywhere and the newest admin preview in between. Total mess, I'm sorry to say that...
