ExchangeImpersonation SOAP error

[m.novelli]

Hi guys, in the last two - three days about 5 customers hit this error during Office 365 backup on most of their mailboxes:

Processing mailbox xxx failed with error: Failed to get folder properties. An ExchangeImpersonation SOAP header must contain a user principal name, user SID, or primary SMTP address.

It's a know issue? I can open a support ticket if needed

Cheers,

Marco

Marco,

Yes, please open a support ticket and post the support ID + follow up after investigation here.

Any change that those users have changed their primary SMTP address?

Hi,

Same error for me.

Did you find why ?

Hello, my case id is 02192153

There was no changes on user configuration

I'll let you know about the solution, I suppose is some back-end change made by Microsoft on Office 365 backend

So far non really helpful the Support Ticket:

Thank you for the actual logs. I see the details of the issue: this error occurs on the Exchange level and is not related to Veeam directly.
Here's a couple of Microsoft articles that might be helpful in this case:

We also can open a Microsoft support case on your behalf and engage in a conference call with Microsoft support to help identify the issue and show that it is not Veeam-related. If you need such assistance, please provide me with your Microsoft ID (SAxxxxxx).

Please let me know if it helps.

Hi Marco,

I think you went to the next tier with support and are doing some more test before doing a joint call with Microsoft. Correct?

[m.novelli]

Yes, I'll let you know about progress!

After some tests seems to be some Office 365 / Microsoft issue with “ApplicationImpersonation” role assigned to user running backups (I was pretty sure about that)

Manually assigning the “ApplicationImpersonation” role / permission doesn't solve the issue

Actually I have about five Office 365 tenants with this issue, ranging from 1 to about 10 mailbox that fails to backup on each tenant

I have to contact Microsoft for further analysis but... I think will lease things as is

Cheers, Marco

Marco,

Sorry to hear that it didn't work out. Those users that you are using (from what I can see in the support case) are they actually having an email address? Any change they are unlicensed users or other type of users?

[m.novelli]

Yes, they have a mailbox and they were backupped successfully just a week ago

One of the mailbox on one tenant is my working account...

Ciao
