Hi, We have received an undeliverable notification via email to an email address that has been sent to in the past. 

 

The email address exists and is correct. 

 

What do you suggest?

Correct answer Meenakshi Negi

Can confirm now here it's fixed too. 


Hi andrey_0108 and Synergist5EB8,

 

Thank you for confirming the fix. This behavior was caused by a backend issue, which was resolved on the same day you mentioned.

Please don't hesitate to let us know if we can help.

 

Thanks,

Meenakshi

We're also experiencing the same problem as of yesterday 29/04/25. The messages are not in our spam folder in Outlook and if I look in Recent Notifications within the Adobe Acrobat Sign interface it shows all the failed events and they show as "bounced and could not be delivered". If I send a test email to our address from gmail it arrives without problem.

Adobe - have you changed the way you send notification emails or the format thats resulting in them being rejected by users of Microsoft365 email?

We have the same problem. A few days earlier it was ok, any idea?

Hi Meenakshi,

 

It doesnt seem to affect all recipinets that we send documents to for signature. In fact it's only affected one yesterday and when we re-tried the same address 30 mins later it was received fine. The problem we are having is us receiving notifications of sent and signed agreements. We can send a test agreement to ourselves and it comes through fine, but the notifications to the same address are not being received. I'll private message you with the address concerned.


Hi Meenaksi,

Have you managed to make any progress on this? We're still not receivng notifications and we havent made any changes to either our Abobe Sign account or our email system config (Microsoft365). They are still showing as 'bounced and could not be delivered' in 'Events and Alterts' even though all other emails that we have tried are getting through to that address? I private messaged you the address concerned yesterday but haven't heard anything.

We're having the same issue: It is undeliverable via email all of a sudden although no new emails are being used (has worked before), the receiver gets a notification in the adobe app though.

Hi Workbooks25999171c38p,

 

Sorry about the delayed response.

 

This seems to be weird behavior. Please confirm if the issue was resolved after whitelisting the email at the recipient's end.

If the issue still occurs, let us know.

 

Thanks,

Meenakshi

A number of us at my company are having this issue. It isn't linked to whitelist.

 

There seems to be an error within Adobe that is causing this. Some notifications get through, some just don't. It's annoying and random because you know the person's email is valid and earlier in the day they may well have received and signed documents. And then for another batch, they don't get the notifications and Adobe says it's undeliverable.

Have the receiver "white list" adobesign@adobesign.com.
