[SOLVED] Share will not create

[folioguru]

We have a user, galsync@domain.com, which we use for global lists and calendars.
There are 15 of 50 users for the domain. We added a new user and tried to create the share by
Right click Calendar

Select Share

enter user e-mail address

viewer

send standard e-mail
try to click OK - no response from Zimbra only cancel works. This occurs for two address books and calendar. Share is being done as galsync@domain.com
We can share another user's address book and calendar successfully.
Anyone have any ideas?
TIA, Mark

It appears there is an issue when GAL does not have Receive Mail checked off. By checking "Receive Mail" it allowed the share.
So interim solution is turn on/turn off
