My clients Windows 7 PC with MS WLM 2012 suddenly stopped receiving email, her other devices checking mail were behaving normally. The unusual aspect to this being that clicking Send/Receive did not give the expected commentary items down in the application Status Bar (bottom right of the window), ‘Checking mail…’, ‘Authorizing…’, ‘No new mail messages’.

Suspecting a damaged installation and after doing a full message export for peace-of-mind I tried to repair the application from the control panel / Programs – the item is ‘Microsoft Essentials’ – select and then click repair. This made no difference. I had noticed that WLM had some other non-standard icon buttons in the interface which belong to BullGuard Anti-Virus. After further testing I found that disabling the BullGuard Spamfilter allowed the mail to start flowing – even after re-enabling the feature later. Application re-starting and/or PC re-booting might also be necessary after turning-off Spam protection.
