I want to create a new site collection with url /sites/PMO/, but I am getting this error:

The site collection already exists. Please enter a different address.

Permanently delete the site collection from the recycle bin and continue.

As follow:

But I checked our recycle bin and it does not have any site. Also I checked the modern site collection and none of them have this url /sites/pmo/.

So not sure why I am getting this error? and which recycle bin it is refereeing to Permanently delete the site collection from the recycle bin and continue. as our recycle bin is empty, as follow:

    how long you wait before create new site collection? i mean after deleting from recyclebin, it should be quick but just wondering. what you get when you browse the URL, file not found?

  • @WaqasSarwarMVP i think 9 months ago i created a site with the same url sites/pmo/ but i have removed it from from recycle bin at that time.. maybe Microsoft keeps this site somewhere for longer time? that why i am getting a checkbox to permanently delete this site from recycle bin? for example we have an active site "/sites/hr" and when i intentionally tried to create a new site collection with the same url, i will get a message that the site already exists,

    I agree, i did the quick test with couple of combinations and every one works as expected. two things you can try, 1st run the powershell get-spodeletedsites and see if it return PMO or try to logout from the tenant and clear browser cache...login back and try agin....lastly you can check that box (permanently)

    Yup that was the other thought i have...may be its time frame ( depending upon your datacenter region, may be Who know), other that you can open the support ticket with MSFT.

I think, it is timing issue. Some time it will delete the site collection from recycbin quickly or take upto 24 hours. It is depending upon the resource utilization on your tenant / DataCenter. May be MSFT doing the throttling so thats why it take upto 24 hours (typically after 24 hours it clear the throttling limit).

Couple of things, we can try.

  • logout from tenant, clear the cache and try again.
  • RUN get-spodeletedsites and make sure it is not returning the site
  • when creating the new site collection then check the box (permanent delete site collection).
  • if issue still there after 24 hours then contact the support.
  • for the 24 hours are you talking about the time to delete old site collection? or for creating a new one?

    When you delete the site collection (PMO) from recycle bin in new sharepoint admin center? Do you have any information right or retention policy on that site collection

  • i removed the site collection from the recycle bin just after creating the site in couple of weeks.. so at-least the site collection was removed from recycle bin 5 months ago !!
