Schedule an Online Meeting on behalf of someone else


It is possible to give someone the permission to schedule an Online Meeting on behalf of someone else?


Yes Smile


Let’s have a look

Step 1. Setting the scene

In my demo environment I have two mailbox-enabled user, one is my own test account Ilse, and the other one belongs to my colleague Annelies Bulkens. I have configured both Full Mailbox Access, and Send-As permission on Annelies her mailbox for me:



Thanks to the changed Autodiscover feature in Exchange 2010 Sp1 and Outlook 2010, when opening up my mailbox, I automatically get Annelies her mailbox and archive added!


More information about this can be found here:

I’m able to send mails as Annelies Bulkens, and I am able to schedule meetings as Annelies!


But when trying to schedule an Online Meeting, or when trying to change an existing one to an online meeting, I get the following error message: “Please contact the owner of the account to get delegate permissions in Lync”:


Step 2. Getting delegate permissions in Lync

In order to get delegate permissions in Lync, Annelies has to log into Lync, and add me as a delegate. Just go to Tools, check Call Forwarding Settings:


Click on Edit my delegate members:


And add on the following screen Ilse Van Criekinge as a delegate:



Click OK, and that’s it.

I will get a notification in Lync that I have been added as a delegate for Annelies:


And from that moment onwards, I’m able to schedule an online meeting on behalf of Annelies Smile


Step 3. Dealing with Non-Enterprise Voice enabled users?
The above steps can only be used to set delegates once a user is enabled for Enterprise Voice! But if you disable that user for Enterprise Voice, the delegate settings will remain!
No need to temporarily enable and then disable Enterprise Voice again using a client policy. I've already talked about Client Policies in one of my previous posts available here (, and you need to use the following attribute EnableExchangeDelegateSync!
Copy-Paste from the TechNet article:



When set to True, delegates a user that has configured in Microsoft Exchange will be allowed to schedule meetings for that user.

Just adding a calendar delegate with the permission to schedule meetings on your behalf, and Online Meetings can be scheduled as well 🙂

  1. Ilse, wouldn't it be simpler by doing so with Set-CsClientPolicy -identity "Global" -EnableExchangeDelegateSync $true

  2. Kate Robertson says:

    Followed your instructions in step 3 but still getting the "You do not have permissions…" error message. Have verified that EnableDelegation in the CsVoicePolicy is also set to $true. We are able to bypass the error by toggling the Enterprise Voice setting but this isn't ideal.

  3. Keith Newton says:

    besides EnableDelegation in CsVoicePolicy, EnableExchangeDelegateSync in CdClientPolicy and 'Full Mailbox Access' / 'Send on behalf of' permissions in Exchange, is there anywhere else to check?

    I'm still getting the permissions error when delegates try to schedule online for their managers 🙁

    should this feature work if the manager is using Lync/Outlook 2011 for Mac and the delegate is using Lync/Outlook 2010?

    all suggestions appreciated.

  4. Wayne Millet says:

    Seems that delegation sync has been broken by most recent client security update as I can no longer get delegates to sync. Process was working well last week and now will not update.  Any known issues with the June 2012 security updates?

  5. Hayden Hancock says:

    We do not use the enterprise voice option and had to follow Step 3; however, it still doesn't work. We receive the same error when trying to setup Lync meetings.

  6. For Non-Enterprise Voice says:

    I have tested all scenarios on all Lync clients and now on Skype for Business clients.

    For 98% of the cases this works great, but there are some users where this doesn’t work at all no matter the combination of rights I try on both.

    Is there any update on how to force this right to a user?

  7. Still an Issue says:

    This issue remains. I can find nothing on any forum about why synchronization breaks for some and not all when delegation sync is enabled.

  8. Resolved with SEFAUtil.exe says:

    Use this tool from the ResKit to save the day.
