Disable Adobe Collaboration Synchronizer - Adobe Acrobat Pro 2020 & Windows 11

[ryan_1826]

Before I start downloading tools or editing resgistry keys, is there a simple way to keep Adobe Collarboration Syncrhonizer from firing up? It is diabled on startup. In Acrobat Pro 2020 Pereferences>Adobe Online Services I have unchecked "sync preferences across devices and document services."

I only use Pro 2020 and do not use any Adobe cloud services/sharing. Windows 11.

Thanks!

Go to Edit > Preferences > General. Look for any options related to "Automatically check for updates" or "Background Updates" and ensure those are also unchecked. Sometimes, background processes related to updates can trigger other Adobe services.|

If this doesn't resolve it, the next simplest level of intervention would involve using the Task Manager to manually end the "Adobe Collaboration Synchronizer" process each time it appears. While not a permanent solution, it's a quick way to stop it without making system-level changes.

FWIW, if you're on a Mac, it's located with Preferences > Internet > Allow speculative downloading in the background.

Nice one Adobe.

I had high fan and the corresponding high CPU usage in task manager. I could see it was Adobe but the articles are confusing on this subject. As mentioned here I killed it over and over in task manager and that showed it was causing it. I then looked for a way to stop it. I have Adobe Acrobat Pro 2020 and it is up to date. I never use it online for anything I'm aware of at least. All my files are local and backed up on One Drive, I dont "collaborate". I simply renamed AdobeCollabSync.exe to AdobeCollabSync.exe.orig. That stopped it; and after a week, many reboots and uses of Adobe, I have no issues or errors thrown. I can't guarantee anything here but its easy to reverse with a rename. It worked so far but I have no idea if an update occurs, if that ever happens on a 2020 Adobe, if it will come back. Its not an original idea you'll see it in searches but until you try it who knows its the internet.

I did this today. I'll report back in a week. Thanks for the suggestion!

Three days later and the process hasn't restarted. Haven't had any functionality issues with my Abode Acrobat. Thanks!

Thank you for this simple solution. It's been working great for me, so far. Was so frustrating trying to work through all the possible solutions community suggested. Yours is the only solution that has hopefully permanently "fixed" this issue, until Adobe puts out a real fix.

I have done the same as of today and we'll see if high fan stays off. I do notice that I have Adobe on my Firefox as an extension, so I'll try this and if it continues I may have to remove the Adobe extension from Firefox so it's no longer interacting directly, though I imagine it may make opening .pdf's different instead of a direct function. Will update if something changes. Thanks for the help!
