Hi @Semih Öztürk​ ,

Check with your IT on delay or latency, don't think code level fixes are required.

Sure @Semih Öztürk​ 

Hi @ChanduMohammad S​ 

Thanks for the reply. I think so too, something might be about the system.

ill ask my manager,

Hi @Semih Öztürk​ ,

Does the above issue happen for the particular mailbox or all the mailbox? If the issue happens for the particular might you have to check/repair the MS Office products in the machine. Also, please check any major windows updates are pending on the machine

Hi @Tamil Arasu​ 

Thanks for the reply

particular mailbox for one company. But if it needs come cleaning and stuff, wouldnt it do delaying in all send:mail actions?

for example, yesterday it did delaying when sending mail, but today it worked on time perfectly, i didnt do any cleaning

what should i check in the ms office? is there anything specific, or just need to repair from control panel?
