We're not the only ones to have this issue so I wish Microsoft would come up with a proper solution. I think it's probably the former so this fix would no longer work. I don't know if it means the flags setting won't take effect after this or it just means the setting would be removed from the command line.

"However, this workaround will only work until the Google Chrome 94 update as the said command line flags will be removed after that." Unfortunately it also states further down that page: This is workable for myself and other admins but not suitable for end users. I tried this and it does seem to work with both Chrome and Edge. "Those who wish to disable the said SameSite flags can do so by adding –disable-features=SameSiteByDefaultCookies or –disable-features=CookieswithoutSameSitemustbesecure in the Target field of the Google Chrome or Microsoft Edge properties and restart the web browser." I would think that now that Edge is based on the Chrome engine, this is why it will have the same problem. As soon as I updated to 8.1 the invalid canary message appeared. When I was running 7.6 & 7.9 I could do what I needed to in OWA.

I downloaded a couple of older versions of Chrome (7.6 & 7.9) plus v8.1 This could end up being a major issue so I'm hoping there is a fix for this. But we can't get staff to do this as they know the mail server by external url. If I change the link in the browser for owa/ecp to the local 2010 servername we don't then get the error. I have also rebooted both servers with no success. I have checked the case of both the owa and ecp URLs and they are all now lowercase. The second comment on the above link is the same setup as us and no-one replied to the person's query.

Our 2016 is a fresh install so would have had these updates installed already. I have also found this link where someone says they have just started getting the issue after installing the recent 2021 Exchange security updates. I've seen references to this from years ago which say it's fixed in 2010 SP3, but we already have this installed. They are now getting the "Invalid Canary" message when trying to do this. Staff and IT use OWA to set out of office messages for themselves and other staff. Already posted a couple of questions regarding our Exchange 2010 -> 2016 migration and here's another.Įxchange 2010 SP3 with Rollup 32.
