When trying to install Veeam Backup for Microsoft Office 365

Cannot proceed with he installation. Port required for product operation is occupied. I had to stop IIS for it to continue

Hi David,

First: Welcome to the forums!

The only ports that I am aware off is 9191 which is used for Veeam Explorer for Exchange and 80,443 to create a connection to Exchange Online but I am not sure why it stopped the installation. Are you running something specific on that IIS server?

Just to add, I found this post due to the same error when upgrading from Veeam for O365 1.5.0.11-something to 1.5.0.1309

When the error popped up, I opened a command prompt, ran "iisreset /stop" (waited for IIS to stop) then went back to the stuck upgrade, clicked 'retry' (upgrade finished successfully), then back to my command prompt and "iisreset /start". All working fine now.

Regarding

Are you running something specific on that IIS server?

I have two websites, binding are...

Default Web Site = 80
VeeamBackup = 9080 (http) & 9443 (https)

running netstat shows...

Proto____Local Address_____Foreign Address_____State
TCP_____0.0.0.0:9191______0.0.0.0:0___________LISTENING

Michael,

Thanks for this. Do you still have the logs. I would appreciate it if you could create a support case (non-urgent one) so we might (hopefully) find what this is.

Thanks
