Exchange 2010 and SendAs problems

[darrenmcginnis]

Hi All

We setup our own Exchange Server as part of a complete server refresh a few months ago, and now it is hit and miss whether the SendAs works or not.

I have a Helpdesk mailbox that I SendAs when I need to send anything out, if you add the email address in to my Outlook and go to send a email, it comes back with "You can't send a message on behalf of this user unless you have permission to do so. Please make sure you're sending on behalf of the correct sender, or request the necessary permission. If the problem continues, please contact your helpdesk."

I have tried removing the rights, I have tried leaving it 24 hours, It sometimes works if I remove the email address from my Outlook "From" field and retype it.


It has been working for about a week, but when I tried to sort out someone elses SendAs for the accounts it stopped mine (presumably when I restarted the Information Store service). I have noticed that I am currently running native SP2 and not any additional RollUps. Could this affect it?

Many thanks

Can you try using a group and give that send as permission and put the users in that group and test/monitor.

Standard AD Group?

Assign Full Access to the User
And SendAs to the group?

[sukh]

yes, std sec group

[darrenmcginnis]

yes, std sec group

Done that

Added my user into a New Sec Group
And assigned the Sec Group SendAs perms to the Helpdesk user

Will try tomorrow when it takes effect

We had exact same issue, and only way we could get it to work was to enable the send as permission and the send of behalf of permission as well.

This didn't work

It was in both before, but it was really hit and miss. The only way I could get it to work was to remove the email address in the "From" section of Microsoft Outlook 2010 and re-add the email address.

I have left the SendAs Permission as the Security Group "HelpdeskOperators" and then went into the Properties of the Mailbox, then "Mail Flow Settings" then "Delivery Options" and added my User into the "Send on behalf" "Grant this permission to:" section.

I also have the "Forwarding address" to forward the email to my email address and the "Deliver message to both forwarding address and mailbox" ticked as well.

The reason I said use a group was Exch will cache this so as soon as you add a user to the group they will have send-as permisson rather than waiting for IS cache refresh or restarting the IS.

Are you saying the permisison is being lost or is still retained but end users can't use send-as?

That makes a good idea, thanks for the info.

The settings are being retained, so when you go back in they are still there. But it just doesn't let you SendAs, it comes back with a email from Exchange saying:

Subject: Undeliverable: printing
To: My Full Name

Delivery has failed to these recipients or groups:

Full Name of User
You can't send a message on behalf of this user unless you have permission to do so. Please make sure you're sending on behalf of the correct sender, or request the necessary permission. If the problem continues, please contact your helpdesk.

** UPDATE **

I have tried this with a user, when they have Full Access and their name added to the "Send on behalf of" in the Mailbox properties, they can reply to emails BUT they cannot SendAs the user - i.e. a new email. When they reply to the email, it says Joe Bloggs on behalf of Helpdesk for example.

But I need to be able to:

Send emails from the Helpdesk mailbox to all the staff
Receive emails into the Helpdesk Mailbox and to my personal user
When I reply to a email that is sent to the helpdesk email and delivered to my Mailbox, to have the words "Me on behalf of Helpdesk".


Is this at all possible?

Currently, I can reply to any emails that is sent to the Helpdesk mailbox FROM the Helpdesk mailbox, and I can reply to a email that is automatically forwarded to me when it has been sent to the Helpdesk. If I click the Helpdesk email when I compose a new email, a error report comes back saying I do not have the permission. BUT if I remove the email and type it in again after selecting "Other email address" it works.

Is there something else set elsewhere that could be stopping it? Perhaps to do with the Address List?

Pick a user and delete their OST file and put them in online mode and monitor.

Can you easily repro the issue or is it randon?

I have removed all my files in the C:\Users\USERNAME\AppData\Local\Microsoft\Outlook and went into Control Panel and them Mail and then Accounts and remove the Tick in "Use Cached Mode". Then opened Outlook

It is easily reproduced as I went into a generic mailbox SendAs wizard and added the username of the person that needed to send emails as that user.

If this doesnt work, then I will apply the Rollup 4 over the weekend.

I created a new email, selected it to come from the helpdesk email address, typed in for a different email address and when I clicked send a dialogue box pops up now saying "You do not have permission to send on behalf of the user"

[sukh]

Is that for the user who is in online mode and has the send-as permissions?

How many DC's do you have?
