Veeam stopped emailing alerts via smtp.office365.com after VM hardware change ??

Hi all....

 

Veeam stopped emailing alerts via smtp.office365.com after VM hardware change ??

 

 

I changed network card type on its VM. It worked all through the night then stopped mid morning today - probably not the hardware change then.

 

 

Is anyone else getting this ?

Server and auth details are definitely correct. Veeam support cant find anything wrong either.

 

Is it O365 ? Everything else is working with it though.

 

 

 

Cheers in advance :)

Could it be that the office365 smtp server/s have tagged it as spam?

 

I know this happens in Google with their smtp servers? currently having a similar issue with Veeam myself?

@bossman ... Don't think so. Its was working fine until about 11.00 this morning. Then just stopped. When I ran a test it gave the error above. I'm stumped.

Its gotta be a Veeam fault. For comparison, my Papercut server is sending mail via O365 without error.

Having issues with Veeam myself, started off great, full backups taking a couple of hours instead of days with BE but then it has gradually started slowing down to virtually a standstill, have an open ticket and uploaded log files.

 

We have a unique setup with our Hyper-V coupled with our Synology cluster and standalone Synology backup unit so I feel this needs tweaking, as for the notifications I have started receiving them again yesterday from the Synology units but not Veeam will look into it further when I have the time, if you find out anything let me know please and vice versa, have a good day :)

If you apply all software updates and firmware updates it might improve speed. I got a 2 netgear nas units and I upgraded to the latest firmware and speed has improved so had applying windows update to the cluster. I am using veeam free version.

OK I've solved it.

 

The network adapter was changed from E1000 to vmxnet3 which worked initially.

 

The machine was networking happily but I noticed that the antivirus updates wouldn't update either.

No relevant ports were blocked and no firewalling was occurring.

 

I removed the network adapter within the VM, uninstalled VMWare tools, reinstalled everything and bingo!

 

 

 

Cheers for the comments guys. Sorted now. :)
