Windows Outlook shows AntiVirus status invalid when Windows Defender is installed

I have a Parallel's Windows desktop running on a new MacBook Pro. I am running Bitdefender as the security solution on the Mac side and Windows Defender on the Windows side. Outlook in Windows keeps displaying a message that another program is trying to access email. After researching, this is due to the antivirus status in Outlook being invalid (Options...trust center...trust center settings....programmatic access...antivirus status). Windows security shows the antivirus status as active and fully up to date. Has anybody seen anything like this? I have run through all the troubleshooting steps in Windows and there is no logical reason the antivirus in Outlook should show as invalid per Microsoft documentation. Any help would be appreciated. Thanks in advance.

 

Hi , I have the same problem in my M1 Macbook running WIN11 ARM : Outlook behavior is unfortunately the same ...

 

I have the exact same problem. It makes no sense, and it's quite annoying. Help!

 

Same problem here! Please fix

 

I have the same issue.

 

Same issue on MBP M1Max. But no issue on my other MBP running Intel.

 

Hello, kindly update to Parallels Desktop 17.1.4 and let us know still the issue persist.

 

Everything was updated yesterday before I posted this and it still occurs.

 

Microsoft® Outlook® for Microsoft 365 MSO (Version 2205 Build 16.0.15225.20172) 64-bit
Running latest version of Windows 11 Pro ARM64 insider preview Eval Copy 25131.rs_prerelease 220527-1351

 

I'm having the exact same issue, outlook doesn't see AntiVirus on ARM M1 Windows 11

 

Same issue here... MacBook Pro (M1 Pro), Parallels Version 17.1.4 (51567), Windows 11 Pro Version 22H2 (OS Build 22621.105) with Windows Defender fully enabled and active, Outlook for Microsoft 365.
I feel like maybe this issue started when I upgraded to 22H2, but I'm not certain. Regardless, it's a nuisance.

 

Same here...MBP (M1 Pro), MacOS 12.4, Parallels 17.1.4, Windows 11 Enterprise 22H2 (OS Build 22598.1) ARM, running CrowdStrike Falcon Sensor service. Windows 11 acknowledges virus protection is active, however Outlook's Trust Center does not acknowledge any active AV software running.

 

Heyooooo! Looks like this issue has been fixed after installing 2022-06 Cumulative Update for Windows 11 Version 22H2 for arm64-based Systems (KB5014958). Outlook now shows my antivirus status as VALID and I'm no longer getting the annoying Accept/Deny prompts for every email.

 

Same here after running the available Windows ARM updates this evening...as well as 'giggling the handle" a bit

FWIW- after running the Windows installs and restarting Windows, Outlook was still not seeing the AV as valid in Trust Center even though Windows acknowledged my CrowdStrike AV as installed and running (same as before the Windows updates). I had to turn on periodic Windows Defender updates, however that did not do the trick, so I then attempted to turn on Windows Defender AV to run in parallel to CrowdStrike however it would not allow it...the slider would just keep bouncing back to Off position even when trying to activate with Admin privs. After going through several gyrations and multiple Outlook restarts (i.e. giggling the handle), I went back into Outlook's Trust Center and the AV now shows as valid and the alerts have gone away.

 

Method 1: Uninstall Third-party Antivirus Software
Method 2: Restart the Security Center Service
Method 3: Run an SFC Scan
Method 4: Install the Latest Update
Method 5: Change Your Group Policy
Method 6: Modify Windows Registry
Method 7: Perform a Clean Boot

This May Help,
Peter
