Incoming emails with attachments arrive hours late

I have Microsoft Exchange email, but I like the Thunderbird more than Outlook. Within the last several months, I've noticed that incoming emails with attachments show up in Thunderbird 3 to 12 hours later than in the Exchange web app.

It looks like the affected emails are only those from within my organization. They briefly appear in Thunderbird but then disappear after the Exchange ATP scan completes, showing up again hours later.

The use for e-mail programs with an Atp Scan.


Contributing factors are factors that can delay delivery. Assessment is that the delay varies from one minute to three or four depending on the time of day. For normal use.

Usually it is about two minutes. Incoming messages with attachments should be checked.

The number of user accounts must be counted before using the level of protection that must be allowed if this an option in the configuration if there is one. This scan only scans mails with attachments.

On both sides try the sender or receiver to edit the exclaimer to bypass attachment scanning.

It is a product that has had little or no development before it. And not administratively friendly.

According to the maker, the answer should be that you have to look outside the product for transport rules and configuration.

Try to find out how this infects Thunderbird It sounds like there is something not compatible with your internal system at the moment on the work floor with Thunderbird. It might be a clue or a simple thing.

Thanks for the reply. Since I'm not an administrator, I'm not able to bypass the attachment scanning.

The reason I think it's a Thunderbird issue is that the delay doesn't occur with the Exchange web app.

I will have to get my IT department involved, but they're so backed up at the moment that I hesitate to clog their queue. Was hoping to solve it on my own.

Hi Lisa, There are three ways I know of to connect Thunderbird to MS Exchange. One involves some specific settings in the MS Exchange setup, which your IT is unlikely to have implemented unless the whole organization is using TB. The other two I know of are OWL ad Exquilla add-ons (both paid, but worth it). You may get some more pointers with your issue if you ask on the add-on page for theone you are using, or look at beonex webpages (both add-ons are from the same company.) If you have one and want to try the other there is a free month trial.

Thanks Agnes. I just tried OWL but can't set up the account in TB because it already exists. I'm not the only TB user in my organization, though we are the minority. Everything works fine in TB without OWL except the delayed emails with attachments.

Here's an update: When an incoming email with attachment is delayed, I can force it to be delivered by closing and reopening Thunderbird.

So what does TB do when it starts up that it doesn't do when it checks for messages?

Hello there lisa14850 We have read your message. We try to help you.

For example

Thunderbird collects your email domain and other technical data to set-up and configure your email account. Other information, like your name, your email messages, and your account's address book are stored locally on your computer and never sent to us

I think it was probably about the same when it starts up it collects as described above. With a data collection when Thunderbird just adds a message or has it checked, so executes an order, much less activities are involved than with an entire registration before starting it, in this case Thunderbird Software.


A start up is more powerful than a single activity. A startup can work, but an activity can't work after that.

But it is not good for your computer to just start up continuously. It reduces hardware life.


Greetings Firefox volunteer.

Thanks. To clarify, I don't need to reboot the computer, just close and restart TB.
