Hi all,

Could anyone help me with the following issue;

I've got some customers complaining ther are getting the following adreses: EX:adres@domain.com

Can anyone please help me out with this issue? How can it be resolved on Exchange? 

Regards,

K. Tupkovic

Hi,

By "they are getting the following adreses: EX:adres@domain.com", do you mean they received emails and the senders' address showed like 'EX:adres@domain.com'? If this is the case, does this issue happen to all senders or just certain ones?

Does this issue happen in Outlook? Please also check if the issue persists in OWA.

If this issue only happen in Outlook, please try recreate the OAB and then check if this issue continues. To do this, please follow:

1. Exit Outlook.

2. Navigate to the following path:

C:\Users\%username%\AppData\Local\Microsoft\Outlook

2. Rename .oab file to .old.

3. Restart Outlook and then Outlook will create a new one.

If this issue also exists in OWA, it's more likely a server side issue, I'd recommend you post a new question in the Exchange forum for further assistance:

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

Hi Steve,

Thank you for the response. I've heard this from certain customers. And this happens when they try to send TO someone who is already in the adreslist. Ill check the OWA before going further with this.
