Delegate cannot create Skype meetings

Arūnas Malūkas

Hi Everyone,


I have a strange situation in my company, that a delegete cannot create meetings on behalf of the delegator. 


There are permisisons set to Editor under Outlook -> Account Settings -> Delegate Access.

Also Delegated access set under Skype for business -> Tools -> Options -> Call forwarding -> Edit my delegate members


Skype client policy under the user exists has a setting "EnableExchangeDelegateSync = True"


Delegator has signed out from Skype and signed back in to confirm the access, but when the delegate tries to create a meeting on Delegator calendar gets a message, that permissions are denied.




Do you have any ideas what else can be missing? I have a lot of other users setup the same way and they are working as expected, except the one that I am describing here. 

Any tips and tricks what else can be done are highly welcome!

what do you get when you run this in powershell on your exchange server?

Get-MailboxFolderPermission -Identity\Calendar -User

-User is the delegated users identity 

We resolved this for users at my company in two ways, both had to do with something weird happening during the exchange migration.

User 1: her msexchrecipienttypedetails ad attribute was set to 3, we compared it to other delegates and found that it should be 1. After making the change, removing and re-adding her from the delegator's skype, and restarting her Skype client, she was able to schedul Skype meetings.

2nd user: her msexch attributes were fine, so we had the skype admin clear her delegate permisssions on the server, then had the delegator re-add her. After restarting the Skype client she was able to schedule Skype meetings again.

In our environment, we normally clear all the delegation permission first between the manager and delegatee to avoid any hanging process/permissions:


1. Remove the delegation from Outlook and wait for an hour to two before adding it back again.


2. Via powershell: 

Remove-MailboxFolderPermission -Identity\Training -User

and wait for an hour to two before adding it back with

Add-MailboxFolderPermission -Identity\Marketing -User -AccessRights Owner




This is what I get when run PS command.


FolderName    User            AccessRights
----------         ----             ------------
Calendar         user             {Editor}

Did you manage to resolve it by removing the permission and add it back couple hours later?

Today I got an answer from the user that it started to work after I applied your proposed PS commands! In addition I also used SefaUtil.exe to remove delegate and re-add it again.
Thank you for your help :)

Today received a message, that the problem appeared again. Any ideas why the delegate keeps loosing the permissions? When I check the settings - everything is setup as it should be, this issue occurred like 3-4 times already...

In addition to resetting delegate rights I always remove the respective Outlook personal contacts for each user.  If a user's email / sip address changes in the global address book but they forget to update their personal Outlook contacts, Skype / Outlook seem to continue to use the addresses from the old contacts.  This just about always clears up any delegate issues.

We also have reports of the delegates losing access every month and it seems to coincide with our pool failover process during patch weekends. Any chance you have a patching process that moves the user or fails the pool temporarily?

Delegate sync has always been flaky for me in both organizations I've worked for as a Skype and Excchange administrator.  I don't think it's just me because I see plenty of others with the same issue.  I don't know if it's a timing thing, a bug with UCWA or something else, but just when you think you've got the combinatin of steps and timing down, you get a call from a user with a problem.  I hope eventually this gets permanently fixed so it's not so quirky.

I am having the same problem. How did you fix it?

We did not find the solution why user is losing delegated access, but we at least managed to fix it to be working again and it's going fine since then.


The major thing that I did not pay attention previously was that both delegate and the delegator must to be online at the same time, when setting delegation.


To try to solve this delete all delegation settings that you currently have.

Exit SfB clients and delete cache from %localappdata%\microsoft\office\15.0 (or 16.0)\Lync\
Start SfB clients again, setup delegation.

Restart delegator's Skype client.


Hope that this will work for you, otherwise I suggest contacting MS support to identify issues specific to your environment.

It seems that timing is part of the equation.  Sometimes you have to wait a couple hours before it works. 

thank you
