fripoll · 22 Jul 2022, 21:57

Hi, thanks for your time:
We use uvdesk community. It suddenly stopped fetch mails and when we run manually the script return this messages

1. Processing uvdesk mailbox configuration.

2. Opening imap stream...
21:15:51 WARNING   [php] Warning: imap_open(): Couldn't open stream {outlook.office365.com:993/imap/ssl}INBOX ["exception" => ErrorException { …}]

3. IMAP stream opened.

No more steps are executed and finsh in step 3.

Credentials are ok
Network connectios are ok
Clear cache done.
Nothing in the prod logs
We also change the connection params with {outlook.office365.com:993/imap/ssl/novalidate-cert} without success.
UVdesk | V -1.0.13
We dont find more tips to try.

Are there some logs where we can view in detail this exception? ["exception" => ErrorException { …}]

Thanks and sorry about my english!

@vipin @peopleinside Magically and suddenly, just like when it stopped working, it started receiving emails again last night. Maybe Azure had changed something.
Thanks a lot for your help.

@fripoll Hi and thank you for your message!
I hope your day is going well.

We can wait a developer or uvdesk staff reply, in the meantime, as we are also in the week end I want suggest this: if the email fetcher started to having issue is because of something that has changed in your server.

Have you tried to update password and configuration for all email configured in UVdesk even if password are correct? If you recently updated UVdesk this is a step that must be done.

You can also read this post: How to debug errors and email fetching errors

I hope you will be soon able to resolve that issue.

@peopleinside hi and thanks for your answer.
We made all this steps, I think its somethink related to microsoft account beacause we didn´t do any change in uvdesk, but the error description is poor and can´t get information about the possible reason. Maybe something about tls version but this changes were made some month ago and didn´t affect our uvdesk. I hope some developer can help us with some tips.
Thanks again.

@fripoll are you sure the issue is not related about the two steps?
If I'm not wrong also Microsoft email support the two steps and if this is active you may need a specific password for application.

Hi @peopleinside The security teams show me logs from azure AD where we can see corrects logins so i try to find something about php version or something else but nothing seems to have change. I found a way to get more info about the error, passing params "-vvv" and "-env dev" to refesh_mailbox command. These are the results.

with -vvv param

$ ./refresh_mailbox_uvdesk.sh

 2. Opening imap stream...

@fripoll sorry, I have no idea about this issue.
If you still never get a reply here you can open a ticket at https://support.uvdesk.com/en/customer/create-ticket/ mentioning this topic.

I will now tag also developers ( @vipin @Sanjeev ) as you are awaiting since 3 days or more. We had also the week end in the middle time.

Thank you for the patience.

fripoll · 25 Jul 2022, 16:43

Thanks @peopleinside I'll be waiting for @vipin or @Sanjeev and trying to solve by myself in the meantime

vipin · 26 Jul 2022, 09:17

@fripoll

which email service(outlook, gmail) are you using to fetch mails?
is your swift-mailer working fine?

@fripoll thank you for your feedback!
I'm glad to read you resolved!

Enjoy UVdesk and your day.

Microsoft blocks IMAP Port for basic authentication. im sure the problem will rise again. to avoid this just enable MFA on your office 365 email and create an app password.

microsoft tends to do so to push all people to use the modern authentication method. ive been in your shoes.
